The homes are constructed with quick-growing Western Red Cedar and engineered wood for the framing and beams. The exterior can be finished with Hardiplank fiber cement siding or pre-stained (with low VOCs, of course) cedar siding. Lindal’s local dealers, most of whom are NAHB Certified Green Professionals, make sure to orient each home properly according to the site and optimum solar conditions. The dealer also helps each home owner pick out and source interior finishes according to their own taste, budget and desire for eco-friendly materials. The pitched roofs can easily accommodate a solar electric or hot water system and a rainwater catchment system.
