The waste  house was built from industrial or domestic waste 

 
   
 
 
 
   
         

The Brighton Waste House was an ambitious project to point out the amount of waste we produce at home and in the construction industry. It challenges our ideas of what waste is and what it could be. Architects Duncan Baker Browne and waste 'guru' Cat Fletcher teamed up to find a wide range of materials which could act structurally, as insulation or finishes, both inside and out. Waste chalk from a local building site was an obvious resource for a rammed chalk wall

Once the design was agreed and the materials assembled construction could begin with a group of industry apprentices and architecture students set to work.

The first part of the building were cassettes made from 'waste' plywood, damaged in transit but perfectly usable. The suppliers would otherwise have chipped the whole pallet of boards thereby incurring cost. The cassettes were made by apprentices off site and assembled on site. With  basic structure in place the formwork for the chalk wall could be started.

Both apprentices and architecture students were involved in the assembling of formwork, the mixing of material and all the other aspects of the build. Chalk was brought on site from a local construction site, this part of Sussex produces a lot of chalk spoil which is mainly used for roadside landscaping. However they are even running out of spaces to do this in the county

which will make disposing of 'waste' chalk pretty expensive.

The wall itself is very simple, one and a half storeys high, a straight line with no services or other complications. The formwork was a commercial system easy to handle and assemble.

The chalk had to have water added by hand and then carried in buckets first to the ground floor and then by rope hoist to the first floor level. Ramming was with a pneumatic tool and everyone had a go.
