Adding onto an existing home is more complex than new construction — the new must integrate perfectly with the old. We start with a structural assessment of your existing home, then engineer the addition to tie in seamlessly. Matching rooflines, siding, and finishes so the addition looks like it was always there.
Structural assessment of existing home before design — identify load paths, foundation capacity, and framing connections
Roofline matching and exterior finish integration so the addition looks original, not bolted on
Phased construction minimizes disruption — you stay in your home through most of the project
Foundation engineering matched to existing conditions — pier, slab, or stem wall as appropriate
Double your living space without expanding your footprint. Structural reinforcement of existing walls and foundation to support the new level.
Expand outward — add square footage to existing rooms or create entirely new spaces. Kitchen expansions, family rooms, and primary bedroom extensions.
Smaller-scale expansion that adds 50–200 sqft to a specific room. Perfect for expanding a kitchen, adding a breakfast nook, or creating a home office.
Convert outdoor space to conditioned living area. Glass walls, skylights, and climate control create a room that brings the outdoors in year-round.
We evaluate your existing home's structural capacity — foundation type, framing system, roof structure, and load paths. This determines what's possible.
Architectural plans that integrate with your existing home. Structural engineering for tie-in connections, new foundation, and any required reinforcement.
Full plan submission including structural calculations showing integration with existing structure. We manage corrections and city approvals.
Foundation work, shoring of existing structure if needed, and preparation of connection points. The critical phase that ensures structural integrity.
Framing, roofline integration, MEP extensions, and finish work. The addition is built to match your existing home in every detail.
Inspection, punch list, and handover. The addition should look and feel like it was always part of the original home.
Additions require a builder who understands existing structures. We've engineered second stories onto 1960s slab-on-grade homes, extended kitchens through load-bearing walls, and added rooms to homes on hillsides. The structural complexity is what we do best.
