Additions — Overview

Seamless additions
done right

Room additions and home extensions are among the most complex projects in residential construction — we have the experience to get them right.

Tying a new addition to an existing structure requires precision at every step — matching rooflines, integrating existing mechanicals, and ensuring the new space is thermally and structurally continuous with what's already there. Rushed additions show. Well-built additions disappear into the home.

We handle everything from sunrooms and garage conversions to full two-story additions. Design coordination, permits, and construction all under one contract.

Common Questions

Additions —
answered straight

Yes — that is the craft of a good addition. We match rooflines, siding, windows, and interior finishes so the new space disappears into the original structure.

Most additions require stamped drawings for permits. We coordinate the architectural and structural engineering work as part of our service.

A single-room addition typically runs 8–14 weeks; second-story additions longer. You get a written schedule before work begins.
