We visit south London, to explore a timber frame home that is nothing like the Victorian-terraced homes surrounding it. The house is a rework of an old woodworking shop on a site that no one imagined. Then we tour a home in a Boston suburb made from the scraps and leftovers from the old interstate freeway. Next in the Hollywood hills, a couple built a fabulous home on a 9-thousand-square-foot piece of land. The design is bold, beautiful and boasts some of the earliest uses of non-toxic materials.
