THE URBAN ASSEMBLY KIT Land use : The most useage in the area is residential then the utilities . And very little commercial or mix use to serve the area . Building The study area can be divide into three conditions : condition: 1- Old building 2- Modern building ( less than 5 years old ) . 3- New building ( less than 1 year or under construction ) Old Building Old building Modern building New building Land use percentage 2% 17% 9% 5% 67% Modern Building Residential Mixed use Mosques Services Warehouses Building Most of building in the area is made of concrete and Building heights: materialsbuildings have there are few of :The majority of the buildings are 2 levels .

Preparing The Master PlanOpportunities and Constraints : Opportunities Constraints Visual link to Old Irgah Built buildings Physical Link to the surrounding Hnifa Land prices valley Rise the commercial use in the area Hot weather of Riyadh city Suitable area for recreational use The possibility of reducing the privacy of the residential areas Physical Link to the current residential area B- Using zero emission transportation : Gathering the governmental uses The transportation for the developed area should not be producing CO2 . The area users will using electrical buses , moving walkway , bikes , Creating new character to the areaUrban design principles and consideration :1- sustainability : A- Using Solar power to generate electricity : all buildings will be covered with solar panels & using the new transparent solar technology in windows which directed to the sun 2- safety : Using a safe movement system which solve the issues of the pedestrian , handy caps , bikers and vehicles interaction . By separated lanes . Speed reduction , cross lines elements , etc. 3- Social: A- Maintain privacy B – linked communityB- Water treatment & reuse : All the buildings will have water treatment systems Development of project program :which will filter & reuse the gray water in toilets or in plantation then send the black usage Cultural Public Commercial Hotel Office Hosing Theme park Square Parking lots Roads Green Water Etc.water to the city water treatment 9.4 5.2 7.5 9 1 12.3 5.5 4.2 5 18.5 19.6 6.2 1.6 % plant.
