An exercise in sustainability and compact living, the Peckham House was recently featured on UK television series Grand Designs.
The house was constructed in London on a tight budget. The site was an "unuseable" brownfield before the project was completed. The design is full of great space-saving ideas, like a spa tub located under a sliding bed and a sink basin in a drawer that slides out of the way when not in use.
