The 20K houses are simple but refined. The cedar-sided Pattern Book House is a stylish variation on the traditional box with a pitched roof.
The most dramatic of the 20K designs, the Bridge House, is an angular, shedlike structure supported by two big steel trusses and cantilevered over a ravine.
The tall, skinny Loft House has a traditional gabled profile. The Roundwood House recalls a funnel, with a roof that slopes downward from front to rear.
