Home / Build / Additions

More house, joined to the old one cleanly

Bump-outs, second stories and in-law suites. The hard part isn't the new space — it's the seam where it meets a house that's been settling for a century. That's the part we get right.

Types

Ways to add on

Small

Bump-outs

A few feet of floor for a bigger kitchen, a mudroom or a primary bath — often without a full foundation.

Up

Second stories

Adding a floor over part or all of the house. We assess the existing structure and foundation before promising anything.

Out

Wings & great rooms

A full room addition on a new foundation — family room, primary suite or sunroom, tied into the roofline so it doesn't look bolted on.

Multi-gen

In-law suites

Attached living space with its own entrance, bath and kitchenette — independent, but connected. Also see Thermasteel ADUs.

Included

Structural & permitting

Engineered structural design, energy code, and the local permit process — part of the package, not your problem.

Included

Matching the existing house

Siding, roof, windows and trim specified to blend — or to contrast on purpose.

Additions run $95k–$210k+

A wide band — foundation type, roof tie-in, and whether it's a wet room drive it. We give you a real number after a site visit.
