The Cothard

 A Single-Story Post & Beam Barn Designed for Everyday Living

 

The Cothard ADU delivers smart, single-level living with timeless post and beam character. Exposed rough-sawn timber and a 10’ enclosed lean-to create a warm, inviting exterior, while the open-concept interior has an impressive 18‘ free-span which offers exceptional flexibility. Inside, two first-floor bedrooms feature vaulted ceilings, complemented by a functional L-shaped kitchen, adjacent dining area, and an impressive 12’x18’ living space. As our most affordable ADU option, The Cothard proves that thoughtful design and classic craftsmanship can be both beautiful and attainable.
