DESIGN IN THE DETAILS
Every surface is intentional. White oak invites touch with its quiet warmth, stone floors ground each step in permanence, and organic pine-tar siding ages gracefully without chemicals. Locally milled larch and hand-cast cement tiles speak to craft at its most authentic—textures that are not just seen but felt. These details transform the home into a tactile experience, where design is lived through the richness of natural materials.
