2. Architectural consideration straw load-bearing and straw
wood construction buildings in points:
• Design, floor plan, modular system
• Foundation options
• Wall thickness
• Finishing plaster
• Buck design
• Material interior/exterior

3. Similarities to conventional house design
• passive solar design
• roof design to accommodate solar/ photovoltaic system
• convenient architectural forms (civic, minimalism, functionalism)
• structures are very sensitive to even load
on the perimeter walls, accordingly the
shape of the roof should be symmetrical

4. Natural house design
• connected with natural way of life
• using natural materials from surrounding environment
• historical local contexts

5. Design, floor plan, modular system
• bales stacked in running bond
• limited surface area of ​​the windows in proportion to walls
• impossibility of mounting interior equipment on walls without pre-treatment
Load-bearing structures
• structures are very sensitive to even load
on the perimeter walls, accordingly the
shape of the roof should be symmetrical

6. Design, floor plan, modular system
• straw bale floor plan in modular grid
• straw performs only the function of thermal
insulation
• structure is a system of posts and beams
Light wooden frames

7. Design, floor plan, modular system
• straw bales are just infill material and their location is
variable
• construction and interior columns remain visible,
alternatively columns remain visible to the exterior
• unlimited openings dimension
Heavy wooden frames

8. Foundation
• ventilated layer under straw bales
• Terrain modifications or pretty high first floor
with specific exterior view
Pier foundation
Chistopher Day

9. Foundation
• concrete slab on foam glass/ insulated piers
• ventilated wooden frame layer on concrete slab

10. Wall thickness
• jumbo straw bales thick more than 1 meter
• depending on position of windowses is sill
emphasized from interior or exterior

11. Plaster finish
• even surface due aplication of diagonal bracing or plywood
boards
• several layers of earth plaster from rough to fine
Invisible straw material

12. Plaster finish
• plaster is applied directly on straw bales
• convenient features for interaction in straw structures in terms of statics and physics
• more plastic and light reflection from the wall is irregular
Noticeable straw material

13. Buck design
• depends on construction system of straw wall
• buck create the kind of window and door opening
• full-width bucks result in squared conventional shape
but narrow bucks allow significant rounding or carving
around windows and doors

14. Materials
• exposed wooden construction
create unique interiors
