Whittled down from a forest, 50 acres of redwood planks from company-grown trees dry in the air yard of Georgia-Pacific Cor poration in Fort Bragg (below). Attractive and rot-resistant, red wood often ends up as siding for houses. In the planned community of The Sea Ranch, environmental architect David Wright designed his redwood house (left) for "pas sive" solar heat. Wright uses insu lated shades to regulate the amount of sunlight passing through steeply angled windows. Concrete walls and brick floor store the heat, which radiates back through the house to warm living space. A wood stove is the only "active" heater.
