The RPA T-100 design is a traditional pattern home based on the American craftsman, shingle, and stick styles. The design emphasizes comfort, beauty, craftsmanship, detailing, livability, and function over size and gratuitous architectural features. It is a modern open plan with the kitchen, dining, and living space located in a large connected but separated main space. The master bedroom suite is located on the first floor in a separate wing, which forms a private outdoor courtyard. The second floor has 3 bedrooms, a bath, and an office with exterior patio overlooking the private outdoor courtyard. Materials include stained cedar shingle siding, wood windows, metal roofing, brick and bluestone exterior patios, and a brick double sided fireplace.
