The Sonoma County home of Lars Richardson and Laila Carlsen is the result of a long-running collaboration with architect Casper Mork-Ulnes. A 713-square-foot indoor-outdoor Shotcrete dining pavilion dubbed the Amoeba provides a loose counterpoint to the more rigid barn structure behind it.
Tucked beneath a grassy roof covered by nearly 200 species of plants and grasses, the structure is virtually invisible from the nearby street. In fact, the 1,400-square-foot house is so well hidden in the earth that it doesn’t seem to register on the radar of local wildlife either. Birds, butterflies, bees, dragonflies, hawks, snakes, lizards, and frogs all treat the house like just another grassy knoll.
