MASTER CRAFTSMAN ROBERT LAPORTE and architect Paula Baker-Laporte moved the headquarters of the EcoNest Company, their design/build firm, to Ashland, Oregon in 2010. Last year they completed a new nest of their own. Featuring a timber frame, clay/straw walls and extensive use of natural and local materials, the two-bedroom home measures 1,510 square feet, and includes the EcoNest business offices.
Laporte adapted his wall system from traditional timber framing and wattle and daub.“It’s a versatile material,” he says. “The clay/straw mixture combines the insulating properties of straw-bale and the heat-storing properties of cob in one wall system.” Builders can adjust the proportions according to the solar opportunity; for instance, the south-facing wall contains more clay, increasing its capacity as a thermal mass. Larsen trusses minimize thermal bridging in the 12”-thick walls.
