Home Additions
Expand your living space with thoughtful additions that blend with your home.
Seamless Integration
Additions That Feel Original
We start with your home's existing architecture and your family's needs. Then we design additions that blend seamlessly while providing the space you need. Every detail is thoughtfully considered from matching rooflines and materials to integrating systems and finishes. The result is an addition that feels like it was always part of your home.

FAQs
Do you design and build additions?
Yes. We offer design‑build with structural engineering and permit coordination, or we can build from your plans.
How do you ensure a seamless exterior match?
Careful tie‑ins, matched rooflines and overhangs, compatible siding/trim profiles, and thoughtful details.
What timelines are typical for additions?
Design/permits: 4–10 weeks. Build: 8–16+ weeks depending on size, complexity, and season.
Can I live at home during construction?
Often yes. We isolate work areas, manage dust, and maintain temporary access as feasible.
Will the addition affect my HVAC or electrical?
We evaluate system capacity and design appropriate upgrades or zoning; all work by licensed trades.
