This house looks normal. Lovely, even. But get up close and you'll realise that it's far from conventional -- because it's made from rubbish. Real, actual rubbish.
We're not talking nicely recycled plastics or reclaimed woods, here. No: the foundations are constructed from blast-furnace slag; disused carpet tiles clad its walls; and the whole thing is insulated with waste, from floppy discs to toothbrushes.
In fact, 20,000 toothbrushes, 4000 DVD cases, 2000 floppy discs and two tonnes of denim offcuts have been used as insulation across the building. In fact, you can peek through the walls in places to see what's keeping the place warm (see below).
The house, designed by East Sussex studio BBM as a research facility and design workshop for the University of Brighton's Faculty of Arts, sits within the grounds of the University of Brighton. Duncan Baker-Brown, one of the architects, explained to Dezeen:
"It's about proving that you can build something with other people's stuff, and that you can make a permanent building out of rubbish. There have been a lot of other projects where people have built sheds or temporary things out of rubbish, but to get full building regulations and planning approval is a first."
The building will be used by students from the university's Sustainable Design course to help them learn and research how to build houses and other products with minimal environmental impact. It will also serve as community centre, which is pretty neat. [Dezeen]
