Craftsman Addition & ADU

Project Overview

This comprehensive residential project added much-needed space through both a main house addition and a detached accessory dwelling unit (ADU), thoughtfully designed to match the home's original 1920s Craftsman architecture. The 800-square-foot addition to the main house includes a new master bedroom suite with spa bathroom and walk-in closet, plus a home office with built-in cabinetry. We carefully matched existing materials and details, including tapered porch columns, knee braces, window trim profiles, and original siding profile milled to match. The foundation was designed to tie into the existing structure, and rooflines were integrated to appear original to the home. The detached 600-square-foot ADU serves as a guest house and rental income opportunity. The compact but complete living space includes an open kitchen and living area, bedroom, full bathroom, and laundry closet. Large windows and 10-foot ceilings make the small space feel open and bright. Matching exterior finishes ensure the ADU complements the main house while maintaining its own identity. Both projects required careful site planning to maintain backyard functionality and privacy. Updated electrical service, new high-efficiency mini-split HVAC systems, and spray foam insulation ensure modern performance. The additions provide flexible living space while enhancing the property value and maintaining the home's historic character.
