Combined concrete and timber frame structure

Description

Open Source Wood Competition submission by Johanna Byrne. As a follow up to my submission to The City above the City Competition, my Open Source wood competition submission is the developed combined concrete and timber frame extension accessed via an atrium from my 1897 terraced Edwardian apartment in South London UK. Composed of circa 35% concrete and 65% timber, additional materials include steel, silicone, rocks or recycled building demolition debris, foil backed plaster walls and timber floors. With insulation infill to triple leaf walls and double leaf roof finished with felt battens and slate. Ecological values include sustainability through the use of sustainable timber and recycled building demolition debris. Mass produced components with all timbers being 50mm x 50mm sections. Walls being 300mm thick and roof 200mm. Upper limit economical span 47600mm long and 36600mm wide. Prefabricated components in storage available for fast track building needs from residential to war and natural disaster zones. Adaptable to a variety of building types. High thermal and critical mass increased fire resistance with a reduction in energy consumption and CO2 emissions. Helping to combat climate change with the first floor providing shelter in the event of flooding with the potential for a metznizene level pending statutory consent compliance and approval. Earthworks foundations and concrete gable walls the only on site building works which include steel bars within concrete foundations connected to steel bar framework to support pre fabricated Gideon’s rock /debris and silicone filled to provide expansion tolerance horizontally and laterally to enhance earthquake resilience, with pre cast concrete panel and timber frame walls also having shock absorbsion and flexibility qualities. The development of this extension would also render the historic building wheel chair accessible. With the double height atrium link generating heat through solar gain in winter and cooling in summer through opening vents. All opes glazed with all doors being fire doors composed of Pyrex heat resistant glass encased in and hung on a steel frame. External concrete panels and foundation Gideon’s cast in Perspex lined formwork for a polished finished. Potential for solar panels in variant locations for the production of energy.

    • Combining different structural materials is good idea and can offer the best project specific results. Adding wood the structure will also improve the sustainability of the building thus allowing to build with net zero carbon foot print housing.
