Home Additions

A good addition answers two questions at once: how the new rooms will work, and how the house holds together once they exist. Proportion, roofline, circulation, and light all have to carry across the seam between old and new. That is a design problem first, and it is where the work begins.

Kinds of additions

• Single-room additions — a larger kitchen, a primary suite, a home office, or a family room.
• Second-story additions — building up where the lot will not allow building out.
• Multi-room expansions — reworking the plan so the addition improves the whole house, not just one corner of it.

Matching the existing house

The difference between an addition that works and one that looks tacked on is almost always in the details — floor-to-floor heights, window proportions, materials, and how the new structure meets the old. The design treats the existing house as a given to be respected, so the result feels inevitable rather than added.

Through permits and build

Additions almost always touch structure and usually require permits. Design, permit-ready drawings, and construction are handled together, with the structural and engineering coordination that additions demand built into the process rather than bolted on at the end.
