WAG (The Working Architecture Group) have been granted planning permission for a new build two bedroom, near-zero carbon house in Homerton, East London. The project, one of three that WAG currently have on display at the Building Centre’s ‘Sustainable London’ exhibition, should be completed on site by the end of summer 2007. This new near-zero carbon home will be constructed using a prefabricated structural timber panel system from Germany. This solid timber system not only saves around 25 cubic meters of CO2 ,which would have been pumped into the atmosphere had a more energy intensive material been used such as concrete or steel, but the wood itself also takes 23 cubic meters of CO2 out of the atmosphere, storing it in the house. The prefab system also has practical benefits as well as being the most sustainable solution. The site, which is currently occupied by two garages adjacent to a Victorian terrace, is very tight, with no space for storage of materials, site offices etc, making a traditional construction process difficult and costly. However, by using this system, once the existing garages are demolished and the basement excavated, the main body of the house can be craned into position and built in a matter of days.
