Additions & Conversions

More space, without moving

Growing family, home office, or rental income. Adding livable space is one of the best investments a SoCal homeowner can make, and we build it from planning through final inspection.

Home Additions

Extra bedrooms and expanded living space that blend with your home.

Garage Conversions

Turn unused garage space into a bedroom, office, or rental.

ADUs

Accessory dwelling units from planning through final inspection.

Backed by real construction experience

Additions and ADUs are structural projects: foundations, framing, roofing, utilities. Our team builds ground-up homes too, so we bring real general-contracting experience to projects many remodelers can't take on.

  • Feasibility and budget guidance before you commit
  • Permits and city approvals handled for you
  • Built to current California code
  • ADU experience with state and local rules
