Project Information

This ancillary dwelling unit is designed as a practical and welcoming home above a new or existing garage. The gable roof, finished with standing seam metal, gives the structure a simple, timeless profile, while warm wood siding softens the exterior. Large sliding glass doors open onto a generous terrace, creating an easy flow between indoors and outdoors. Glass and metal railings maintain an open feel, and wood stairs provide a natural, inviting entry. Inside, the living room is filled with natural light through expansive glazing, offering a bright, efficient living space ideal for a single resident or couple.
