Perth + Elizabeth Quays Brookfield Development

  1. 1. perth+ May 5, 2017 MRA ‘IN PRINCIPLE’ DEVELOPMENT APPLICATION REPORT
  2. 2. Project Vision The Metropolitan Redevelopment Authority’s vision for the Elizabeth Quay Project is to: “Transform the relationship between the city and the river and enhance the identity of central Perth. Elizabeth Quay will be a highly interactive civic space, accessible to the whole region and within walking distance of all major facilities within central Perth.” Brookfield Property Partners’ design objective is to achieve a landmark, mixed-use development set within the new world-class location of Elizabeth Quay. The development will establish a new commercial, residential, and hotel address in the Perth CBD and a clear identity for the Quay. The development will represent Brookfield’s ethos of ‘Best in Class’ when benchmarked against competitive product, and will be a reflection of Brookfield’s commitment to design excellence. Design Response: PERTH+ Anchoring the axis linking Elizabeth Quay, the CBD, the Cultural Centre, and Northbridge, PERTH+ is a beacon, a land-mark between water and city, a signature that celebrates Perth’s future as a world-class destination and global city. In their simple elegance, the two towers of PERTH+ engage their urban surroundings as a modern and confident center point, and complement the desire to have a mix of uses, including retail, offices, hotel, and residences. Less than midway up the taller tower beats a glowing heart, the ‘Plus.’ Perceptible from the ground and at a distance, its cantilevers present a positively disruptive dynamism in the Perth business district. Aligned with the Plus’ longest arm, the smaller tower strengthens the pair’s urban scale, its façade and proportions in perfect harmony with its neighbor. Together, the PERTH+ towers embrace the Quay with new, communal open spaces in the form of a large, civic plaza that extends The Landing and a shared landscaped pedestrian way, both lined with retail, restaurants, and café terraces. Residents of PERTH+ enjoy magnificent views of the city and the Swan River from their sheltered balconies. Restaurants, bars, gym, private dining room for large gatherings, and entertainment room are available to them without leaving the building, at the push of a high-speed lift’s button. Equally favored, hotel guests benefit from the same grand panorama and views onto the beautiful Plus’ landscaped rooftop, as well as first class amenities. Office workers are immersed in the city with views onto Elizabeth Quay’s lively activities, closest to the retail and restaurant venues, and with quick and dedicated access to their floors or the amenities in the Plus. All are directly serviced by ferry, bus, and train. Beyond its architectural and urban value to the city, PERTH+ is designed to adjust its land use with market fluctuations, both during design and over the building’s life. The office floorplates are ideally dimensioned, column free, and easily divisible; the hotel follows guidelines of a high-end brand; the residences are coordinated to maximize sales via flexibility of unit size; and the amenities, in the Plus, combine into a hive of activities and benefits used by the public. Retail and food & beverage on the two lowest floors of both buildings energize the street edges and—in combination with civic-scaled sun shading and wind protection in the public space—spill activity out toward the Quay. In land use, form, and aesthetic, PERTH+ is an opportunity—and an invitation to visit, to linger, to shop, to work, and to live—in an environment worthy of its magnificent setting.

  14. 14. 1,481 m² 1,498 m² The objectives for Lots 5 & 6 seem at odds: a building pair that must be an urban landmark, but must meet the rigor of speculative development and the MRA Design Guidelines, and be adjustable to market fluctuations during refinement. The proposed concept generates value from this very dichotomy. Starting from the MRA Reference Scheme, which permits a maximum of 1,498 m2 and 1,481 m2 for the Lot 5 and Lot 6 tower footprints respectively,… 1

  19. 19. To accommodate the client’s floor areas with minimal overshadowing of The Landing and surrounding public spaces—and to create a focal point for the Elizabeth Quay site—the Lot 5 tower is stretched up while Lot 6’s building is lowered. 6
  20. 20. A clear design direction and aesthetic coherence that nonetheless allows programmatic modulation is achieved by composing the two towers from four discrete elements: three large, efficient, flexible land use ‘blocks’ and one relatively small, highly unique ‘Plus’ of amenities. The land use blocks are maximized to meet the most desirable commercial dimensions. The lower, office blocks have 2,050 m2 floors, 4 m floor-to-floor heights, and a façade grid / planning module of 1.5 m. The upper block contains the hotel and residences, both with 1,530 m2 floors, 3.4 m floor-to-floor heights, and a façade grid / planning module of 1.4 m. Residential Hotel Amenity Office Retail Service / MEP 7 1,530 m² 2,050 m²
  21. 21. By keeping the hotel and residences conjoined and distinct from the office blocks, the ratio of hotel to residential floors can easily fluctuate within the upper block. Residential Hotel Amenity Office Retail Service / MEP 8
  22. 22. The building asserts its landmark stature in two ways. First, within the nine lots of Elizabeth Quay, all but Lot 4—yet to be sold—have similar uses to Lots 5 & 6, including their podium functions. To establish Lot 5’s individuality beyond its superior height, and offer a community asset within the Quay, the hotel, residential, and some office amenities are consolidated into the Plus, a dynamic insert cantilevered from the tower’s core between the lots’ upper and lower blocks. The Plus becomes a beacon visible from around the city. Residential Hotel Amenity Office Retail Service / MEP 9 !!!
  23. 23. Most of the amenities contained in the Plus—such as restaurant, bar, ballroom, gym, and meeting facilities—are open to the public. While roof terraces are likely not possible due to wind loads, the Plus—itself an interior, public amenity—offers spectacular elevated views over the Swan River and Perth’s CBD. In addition to generating a vibrant public magnet, aggregating amenities from the hotel, residential, and office components in the Plus is not only cost-effective by eliminating redundancies, it creates critical mass that affords more impressive facilities. For example, the gym—required by the brief for all three main building uses—can attain a size reasonably leased by a third-party operator. This aggregation also results in providing additional and easily accessible amenities to the offices and residences, which can use the hotel’s ballroom, restaurant, bar, and meeting rooms. Residential Hotel Amenity Office Retail Service / MEP 10 !!! !!! !!! !!!
  24. 24. Clusters of building use are grouped in each of the Plus’ four arms: restaurant / bar; gym / pool / spa; meeting / private dining / game room; and function / pre-function, which also includes the hotel lobby. Each cluster has its own architectural expression, revealed at night to increase its power as an attractor and as a signature feature. By keeping them independent, the architectural character of each cluster can be easily redefined during design, and— by using lightweight, sustainable construction materials—can be adaptively changed over the building’s life. Residential Hotel Amenity Office Retail Service / MEP 11
  25. 25. The second means by which PERTH+ asserts its landmark quality is in its confident simplicity. Amidst the constellation of highly articulated architectural pieces surrounding Elizabeth Quay and the design of the Quay itself, the tower’s pure form—like the tower on Lot 2—stands out. The tall, simple edifices of Lots 2 and 5 create a compositional counterpoint, with Lot 5’s height maintaining the primacy of the Quay’s heart. Its composition—keeping office and hotel / residential separate—gives prevalence to the efficiency and functionality of each use while producing a compelling, elegant, and distinct form. A visual twin to its neighbor on Lot 5, the office block of Lot 6 similarly offers floor plates of 2,050 m2 with a generous clearance from core to perimeter on its southern, river-facing side. By matching the height of Lot 6 to the top of Lot 5’s Plus, Lot 6 compositionally complements the landmark tower, but its subsequent staging does not detract from the latter. 12
  26. 26. The two PERTH+ towers are joined by an open-air pedestrian laneway, a ‘Main Street’ of sorts that avoids the ‘superblock’ effect detrimental to human scale, and retail and urban activation. Lifting hotel and partial office amenities off of grade (many of which—such as function / pre-function spaces and meeting facilities—rarely activate the edges) eliminates the need for an oversized podium while still providing more retail. This enlarged retail is supported by the 3,118 m2 of added pedestrian area around the towers afforded by the removal of the podium, infusing the perimeters of Lots 5 & 6 with light, air, and views. The enlarged pedestrian zone around the base of the towers has three sub-zones. On the north, the towers’ 5 m setback provides a more gracious pedestrian circulation and entries to the offices (prominently located on the northwest corner of Lot 5 and northeast corner of Lot 6) and hotel. Placing the office entries on the outer corners maintains the formal character of The Esplanade. Residential Hotel Amenity Office Retail Service / MEP 13
  27. 27. Residential Hotel Amenity Office Retail Service / MEP Separating the two structures’ bases creates a pedestrian Main Street that can draw people from The Esplanade onto Geoffrey Bolton Avenue and the Quay’s activities. This new artery is lined by retail and restaurants. The removal of the Podium also sets back the towers of PERTH+ from the property line by 14 m, creating a civic plaza 19 m deep without The Landing and 72 m deep including The Landing. Since the development of Elizabeth Quay, Perth has grown accustomed to using Lots 4 through 7 for civic functions. As Elizabeth Quay is completed, these functions will be orphaned. PERTH+ thereby provides an extension of The Landing and area for hosting large civic events By lifting the hotel amenities and some of the office amenities, and combining them with the residential amenities, opportunity is provided to include more retail space at the towers’ bases. The two stories of food & beverage / retail beckon visitors, providing a lively promenade with beautiful views out to the Quay and the Swan River, and from the Quay in to the warmth of cafes, restaurants, and stores. Facing the Quay, sun shade and wind protection canopies define an outdoor public space where food & beverage / retail can spill, art / performance events can be held, or seasonal kiosks can further fulfill the MRA’s plans for Elizabeth Quay. With the public amenities—such as the restaurant / bar—inside the Plus, and the ground plane’s plazas and Main Street, PERTH+ is a landmark destination for urban life and a landmark building on the Perth skyline. 14
  28. 28. Architectural Expression The facade is comprised of a unitized aluminum curtainwall that takes advantage of structural silicone to achieve flush glazing on the exterior, expressed behind an overlay of structural vertical mullions. The structural vertical mullions have been relocated outboard of the facade to create a smaller frame on the building’s interior (increasing usable area and improving aesthetics), to perform as a fin assisting in shading, and to enhance the building’s external beauty. The glass is a typical insulated glass unit with an ultra-neutral, high- performance low-E coating. The typical office floor units are 1.5 m x 4 m, and 1.4 m x 3.4 m for the hotel and residential floors. These sizes allow for competitive bidding, a wide range of procurement options, and straightforward installation of the curtainwall. The facade panels are unitized in the factory into a four-sided frame and hung from the buildings’ floor slabs like a conventional curtainwall. The aluminum fins are connected to one side of the curtainwall unit and the other side is braced by the adjacent panel. This allows the facade to accommodate building movements while also maintaining narrow profiles to maximize sight lines. The residences’ wintergarden balconies, integrated into the facade, protect residents from Perths’ winds while enjoying the outdoors, and provide significant shading that reduces heat gain. Operable panels allow the wintergardens to open to the exerior or close to become an extension of the interior living space.

  32. 32. Building Layout and Orientation Not only does the PERTH+ configuration fulfill commercial viability for the developer, but it increases workers’, residents’, and visitors’ well-being, and addresses the CBD’s urban fabric. The taller tower’s two blocks and its smaller twin add office, hotel, and residential uses to Elizabeth Quay. The office floorplates are maximized at 2,050 m2 with a minimum 12 m core-to-glass dimension, 1.5 m façade grid / planning module, and 4 m floor-to-floor heights. The hotel and residential floorplates are reduced for maximum efficiency to 1,530 m2 , with a façade grid / planning module of 1.4 m and 3.4 m floor-to-floor heights. Occupants on the lower blocks of both towers get maximum daylight thanks to the 22.3 m space between the two structures. Residents and hotel guests above benefit from unobstructed views, thus privacy; natural ventilation through operable windows is also an amenity for all the residential units. The building façade’s fins and the residence’s interior balconies provide shading and shelter from the wind. The façade system is also designed to reduce solar heat gain meeting an environmental criteria of 5 Star Green Star rating. The commercial maximization of PERTH+ does not take away from the towers’ urban contributions. The Plus, with its cantilevers of different sizes, provides visual interest on each of its sides. The towers’ setbacks maintain the view corridors set in the Design Guidelines, even adding a new view corridor between them, key to increasing the connection between the CBD and the Quay. Further, the lack of a massive podium allows for the finer-grained, human-scale landscape and small architectural interventions so essential in the activation of the public realm.

  34. 34. Podium and Tower PERTH+ favors opening the city to the Quay via a landscaped Main Street that runs between the two buildings instead of a large podium—tying the two buildings—whose presence would obstruct views and cordon off access. Removing the podium also reduces bulk and results in 40% more public realm (on Lots 5 and 6) for active uses, including terraces and landscapes visible and accessible to all. In the communal open space freed by the separated towers, strategically placed trees and landforms will serve to ameliorate the wind conditions. By eliminating the podium, The Landing is extended to the buildings’ bases. This improves the Quay’s viability to host the large public events the city has held on the vacant Lots 4 through 7. The towers’ separation also increases the visual and physical permeability of the CBD to the Quay. The main building’s presence within Perth’s skyline is undisputedly important. The towers competing for preeminence with Lot 5 are Central Park Tower (250 m), Brookfield Place (235 m), and 108 St. Georges Terrace (214 m). PERTH+ Lot 5 is a 220 m tall building that asserts itself on the horizon, and even more so within Elizabeth Quay. The tall tower stands as an icon in the city and on the Quay, an elegant, lean volume interrupted by the dynamic Plus, itself a beacon visible from afar as a symbol of the lively activity down on the Quay day and night. The lack of clear differentiation between the three uses inside the towers conveys a unified simplicity and humility that is heightened by the contrasting, bold geometry of the Plus’ cantilevers and their internal, visible animation. The Plus also serves to articulate the tower’s 220 m height, as it sits on top the office block, separating it from the more private hotel and residential uses above. Massing and the long fins of the façade emphasize verticality. Although seemingly simple, the tower’s two upper uses can fluctuate in size through construction without affecting the overall aesthetics.

  40. 40. Envelope Comparison In order to compare PERTH+ with the intent of the Design Guidelines, it was considered important to reference a built form outcome from the Design Guidelines. Thus, two design references have been used, an MRA Reference scheme and an MRA Variant scheme, as defined below. The MRA Reference scheme is the massing shown in the Site Specific Design Guidelines for Lot 5 and Lot 6. The MRA Variant scheme is a massing of similarly proportioned floorplates based on the maximum allowable footprint (60% of the area within the 5 m setbacks of the property line) and in compliance with the Design Guidelines in terms of podium height and setbacks.

  44. 44. View Corridors The four view corridors defined in the Design Guidelines are maintained. From Howard Street looking south, a thin edge of PERTH+ frames unobstructed views to the water. The lower size of Lot 6 opens up skies and views all the way to the Quay looking south on Sherwood Court. From The Esplanade looking west, the corridor is activated by one of the short cantilevers of the Plus recessed and high enough to maintain an open view through. Looking east on The Esplanade, the clean edges of both towers line up with the street edge, and placing the small cantilevered volume in ‘height dialogue’ with the buildings across the street. The building base disappears on Geoffrey Bolton Avenue looking east and west, while the Plus' southern cantilever stakes its iconic claim in the lower sky. And of course, looking south in between the two buildings opens everyone to views of the Quay, the water, and The Bridge.

  54. 54. Communal Space The area between Lot 5 and Lot 6 and the areas in front of both buildings facing the Quay provide the perfect grounds for communal space. Protected from winds and sun by landscape features, both the Main Street and the civic plaza can host café terraces, kiosks, water elements, public art, and various public seating, and can also be taken over for the large events the Quay has been hosting on Lots 4 through 7. In addition, the Plus houses public restaurant, bar, ballroom, gym, and meeting facilities, with views over the Swan River and Perth’s CBD. These public amenities can be accessed via dedicated express elevators so as to not disrupt the office functions and to maintain privacy for the hotel guests and PERTH+ residents. While rooftop terraces are likely not possible due to wind loads, the Plus—itself an interior, public amenity—meets the MRA’s desire for elevated communal space.

  56. 56. Solar Access The purpose of this exercise is to evaluate solar access resulting from three architectural massings—PERTH+, the MRA Reference scheme, and an MRA Variant scheme. While it is noted that the Design Guidelines’ acceptable development criteria may have been formulated based on a one-tower scheme, this assessment is appropriately based on a two-tower scheme. The analysis considers two zones in particular—Zone A, the zone of The Landing as defined in the Design Guidelines, and Zone B, any zone per scheme of at-grade open space on Lot 5 and Lot 6. The analysis is divided into two broad approaches. The first approach evaluates the percentage of solar access to Zone A as allowed by the massings. The second approach evaluates the total area in square meters of solar access, calculated as a combination of Zones A and B. The necessity of the report derives from the Design Guidelines for Solar Access. The team’s interpretation of this criteria is that a zone which is fully sunlit and without impeded solar access would equate to 100%. Conversely, a zone which is fully shaded and thus fully lacking in solar access would equate to 0%. Because the context buildings can be considered an empirical constant, the percentages in this report only include blocked solar access as a result of the three massings in question as a way to isolate the impact from each respective massing to generate a basis of comparison. In addition, the team assessed the three variations with respect to a broader range of annual performance. The analysis was conducted during typical annual benchmarks of the summer and winter solstices and the spring and fall equinoxes, from sunrise to sunset for each day. The morning, midday, and afternoon periods for each day were determined by dividing the daylight hours into thirds, as the times of sunrise and sunset vary per day. A comparison of the PERTH+, the MRA Reference, and the MRA Variant at one point in time being 12 noon on 1 September indicates that none of the massings can achieve the acceptable development criteria. We would question whether in fact a two tower proposition in any configuration can achieve the acceptable development criteria. The assessment of solar access at one point in time (12 noon on 1 September) is not consistent with expectations regarding solar access and therefore the evaluation considered the solar average over the morning (first third of the day), midday (middle third of the day, approx. 11am to 2pm), and afternoon (last third of the day) during the typical annual benchmarks. Key observations from the evaluation of PERTH+ include: • Annually, PERTH+ will achieve 75.8% solar access to The Landing • Solar access to The Landing on 1 September over the morning and midday periods reflects 53% and 50% respectively • During the equinoxes, solar access to The Landing over the morning and midday periods reflects 68% and 54% respectively • Other than a minor reduction in mid winter, solar access to The Landing in the afternoon period is 100%, which provides solar access to The landing after work and prior to evening events • As expected, there is minimal impact on solar access during the summer months Therefore, when considering the amount of solar access to The Landing, PERTH+ provides an annual average of 75.8% annual average and a good level of solar access during the morning and afternoon periods throughout the year. In addition, PERTH+ includes significant public spaces at ground level, which—when taken into account with The Landing—provides additional areas of the public realm with solar access.

  60. 60. Wind Assessment Wind conditions at pedestrian level around the proposed buildings are highly dependent on the construction of the neighboring large buildings. If they are constructed, wind conditions around the proposed development in its current form would be expected to be acceptable for a transient space and pass the distress criterion. If the development is isolated, then the wind conditions would generally be significantly worse and a strategy would need to be developed to make the space acceptable from a safety perspective. Stationary outdoor activities around the site will be difficult to achieve without temporary or permanent local amelioration, such as canopies or dense landscaping. The appropriate amelioration measures for the intended use of the space will be developed after the initial wind-tunnel test results are conducted. The rooftops of the mid-height discontinuity are expected to be exceptionally windy and are therefore not recommended for occupation.

ELIZABETH QUAY DESIGN GUIDELINES REFERENCE OBJECTIVE ACCEPTABLE DEVELOPMENT PERTH+ SCHEME COMPLIANCE Active Edges Developments are to activate the street and lane frontages to create vibrant, diverse, interactive and safe urban environment. − 80% activation to the south. − 50% street level activation to the north, east and west. − Multiple at grade access points. − Variety of uses. − Visually transparent at ground level. − Subject to detailed design. Subject to detailed design. Urban Grain Buildings will provide a high level of permeability by incorporating pedestrian connections across development sites. These lanes, passages and arcades will ensure excellent pedestrian access to the main public spaces within the Elizabeth Quay Project. − High quality pedestrian experience. − Well lit, open to passive and natural ventilation and protected from the weather. − Multiple defined entrances. − Respond to existing connections. − Encourage a fine grain of permeability. − A public space as central pedestrian ‘Main Street’ is offered between Lot 5 and Lot 6. − Multiple defined entrances are provided around both bases of the buidlings. − The pedestrian ‘Main Street’ provides clear visual relationship and pedestrian connection from The Esplanade to The Landing. − The lack of podium also opens up the streets and sidewalks for greater permeability and access to the waterfront and back to the city. Complies with ADC. Podiums All development are to exhibit a ’fine grain’ and ‘human scale’ character at the podium and street level to ensure a quality street edge and reduce building bulk and massing. − Human scale in height. − Consider the alignment and proportion of neighbouring buildings and fit appropriately into the broader city context. − Introduce fine-grain elements and assist in wind amelioration. − Continuous pedestrian awnings to all primary streets and to activated secondary streets. − Active uses including communal terraces and gardens shall be incorporated into podium roofs. − Podium roofs shall be designed to limit potential overlooking of residential areas. − Building bulk is reduced by eliminating the traditional podium and offering 40% more space to pedestrians. − Landscape will be designed within the open public space to provide wind and sun protection. Variation Towers All developments will demonstrate exemplary contemporary design and innovation through the exploration of the tower typology. Towers will be appropriately proportioned and separated to integrate with the existing Perth skyline whilst maintaining important view corridors and minimising any overshadowing of neighboring buildings and the public realm. − Maintain view corridors. − Maximize visual permeability through the site. − Maximize solar access to the public realm and assist in wind amelioration. − Articulate tower at different intervals to break up building mass and maximise views. − Emphasize verticality of tower element(s). − Towers that ‘come to ground’ or occupy portions of the setback areas may be supported if it can be demonstrated that other design criteria have been met. − The four view corridors defined in the Design Guidelines along The Esplanade, Howard St/ Enchantress Way and Sherwood St/Duchess Way are maintained. − The massing ‘blocks’ of Lot 5 articulate a new building typology that breaks bulk. − Lot 6 is kept at lower height to maximize solar access of The Landing and Eastern Promenade. − Massing and facade fins emphasize verticality of towers. − Retail is integrated in lower levels of towers maintaining a clean and modern aesthetic to the ground. Complies with ADC. Solar Access Developments are to be designed to minimise their impact on the Site amenity of the public realm and neighbouring developments. − Maintain minimum levels of solar access- 80% to Landing, 80% to east promenade and 100% to the island. − Consider the cumulative impact of shadow from all development to achieve minimum levels. − Ensure that buildings and open spaces have access to sunlight and outlook. − Orientate new buildings to optimise sunlight and outlook and to minimise overshadowing. − PERTH+ allows 28% solar access to The Landing on Sept. 1 at noon and 48% sollar access to the lower Landing on Sept. 1 at noon. The tower on Lot 6 is kept at lower height to maximize solar access to 100% at the East Promenade. The Island receives 100% sun exposure as well. − Both towers have outlooks to all four sides. Variation Wind Developments are to be designed to provide acceptable environmental wind conditions in the public realm in accordance with the pedestrian comfort criteria for activity. − Report prepared by a qualified wind consultant required with DA. − Short term criteria (does not exceed 13 ms-1) to the south of the site. − Walking criteria (does not exceed 16 ms-1) to the north, east and west of the site. − Subject to detailed design.

  65. 65. ELIZABETH QUAY DESIGN GUIDELINES REFERENCE OBJECTIVE ACCEPTABLE DEVELOPMENT PERTH+ SCHEME COMPLIANCE Architectural Expression Buildings within Elizabeth Quay are to demonstrate exemplary design quality of an international standard, generating interesting, innovative and creativearchitectural expression whilst remaining respectful to the Perth context. − All buildings must be designed by registered architects. − Demonstrate innovative design by incorporating contemporary construction techniques and architectural excellence. − Respond to adjacent buildings, streetscape design and city identity when developing a design solution.− Buildings on corner lots are to provide a legible and memorable experience. − Signage and graphics should be an integral component of the design of buildings and facades, to avoid ‘cluttering’ the public domain and to compliment the architectural expression of the building. − REX Architecture PC is led by registered architect in the US and will work with locally registered Architect of Record. − Building shape, organization, and sequencing of construction sets a new building typology. − The scheme continues Perth historical block structure and complements the existing urban massing of high-rises in the CBD, while at the same time creating a landmark through its iconic cantilevered Plus and the building height of the Lot 5 tower. − The fin facade of the tower is brought to the ground to unify the appearance of the ground floor yet allow integration of signage and graphics without ‘cluttering’ the public realm. Complies with ADC. Materials Developments should incorporate the use of high quality locally sourced materials to create innovative and exemplary design outcomes whilst recognising the cultural significance of the site. − Materials should be of an extremely high quality to reflect the significance and the cultural heritage of the site. − Materials should be locally sourced to minimise embodied energy levels and create a unique sense of place. − The material selection should be appropriate for the Perth climate and reflect the broader West Australian landscape. − Materials should be employed and detailed in ways that are innovative and non- conventional. − Subject to detailed design. − Subject to detailed design. Building Layout and Orientation To enhance the amenity of residents and workers all buildings are to be designed to provide usable functional spacesthat accommodate desired uses in a manner that maximises solar access and passive ventilation whilst minimising overshadowing and overlooking of adjacent buildings. − Maintain view corridors.− Provide at least 20 meters spacing between towers to secure outlook, daylight access and privacy for residents. − Provide appropriate shading to windows to minimise solar heat gain, considering orientation, glare, etc. − Towers are to be designed to ensure that all sides of the building provide visual interest. − View corridors defined in Design Guidelines along William St, Howard St/Enchantress Way, Sherwood St/Duchess Way and Barrack St are maintained. − Residences are above tower of Lot 6 and have outlook, daylight access, operable windows, and privacy on all four sites exceeding 20 m. − Reduction of solar heat gain has been considered in facade system to meet environmental criteria of 5 Star Green Star rating. − Asymmetrical composition of building massing provides different visual appearance from every side. Complies with ADC. Communal Open Space Podiums and tower roof spaces will be designed as accessible and functional areas for communal use by residents and or visitors. This is not applicable as the objective relates to communal open space for residents and or visitors. − Programmable public areas are shown at building base and at amenity levels. − By removing the podium, the additional open space at the towers’ bases can be used as an extension of the landing for hosting large civic events. − The amenities within the Plus provide additional areas for communal gathering for not only the residents, hotel guests, and office workers, but also the public. Complies with ADC. ELIZABETH QUAY DESIGN GUIDELINES REFERENCE ACCEPTABLE DEVELOPMENT CRITERIA (ADC) PERTH+ SCHEME COMPLIANCE STATEMENT Design Intent Towers should not present as a ‘wall’ of development to the north of the Inlet and the extent of area between Howard Street and Sherwood Court occupied by a single tower should be minimised through an appropriate design response such as: − Orientating the tower off a direct axis with the street grid; − Incorporating secondary setbacks at upper levels; or − An innovative design solution with different sized floor plates oriented to different views. − Two separate towers are proposed. − A central view axis as a pedestrian ‘Main street’ in between them creates pedetrian and massing permeability while continuing the urban grid. − The office blocks at the base of Lot 5 and Lot 6 are discretely larger than the upper block of Lot 5 occupied by residential and hotel uses. This uniformity interrupted by the Plus gives the PERTH+ its elegance and dynamism. Complies with ADC. Preferred Land Use − Ground Floor: shops, restaurant/café, tavern, small bar. − Upper Podium: shops, restaurant/café, office, residential, serviced apartments and hotel. − Tower: office, residential, serviced apartments and hotel. − Both buildings provide retail and restaurant spaces IN their lower two floors. − Lot 5 uses consist of office, hotel, and residential. − Lot 6 houses offices.
