Project Details:
The Shelburne ADU is a thoughtfully designed 400-square-foot accessory dwelling unit created to support future on-site caregiving while providing a comfortable, independent living space. Built as a standalone structure with its own electrical panel, plumbing, and mechanical systems, this project reflects how small-footprint design can meet real family needs with flexibility, efficiency, and beauty.
The design began with an online concept the clients were drawn to, which was then carefully customized to suit their property, goals, and long-term plans. The result is a high-performance ADU that feels both practical and personal — designed to fit seamlessly into the site while offering a warm, modern interior and durable exterior.
Sustainability was a key part of the build. The exterior is wrapped with TimberHP wood fiber insulation, a bio-based material made in Maine that serves as a natural alternative to foam board. Combined with cellulose insulation, local siding and lumber, local hardwood cherry trim, fir ceilings and cabinets, and Sierra Pacific windows, the project brings together natural materials, regional sourcing, and energy-efficient construction in one compact, highly functional building.
