Additions & Extensions

Add square footage without compromising the home you already love. New work that ties seamlessly into the existing structure — inside and out.

A successful addition disappears. From the outside, the rooflines align, the siding matches, the windows belong. From the inside, the new ceiling height, trim profile, and floor transitions feel original to the home. That's the standard.

We handle additions ranging from a 200 sq ft kitchen bump-out up to full second-story additions that double a home's footprint. The most important phase of any addition is the planning — tying new framing into existing structure, sizing the load path, matching exterior materials, and sequencing so the existing home stays sealed and livable throughout.

If you're thinking about an addition but aren't sure whether it's the right move versus moving or renovating, we'll walk through your existing layout and tell you honestly what's realistic.

Common questions

The honest answers.

How long does a typical addition take?

8 weeks for a smaller bump-out or sunroom; 4–6 months for a primary suite or full second story. We'll give you a realistic schedule with the estimate.

Will it look like an addition or like part of the original home?

The goal is invisible from the curb. Siding, rooflines, interior trim — we match the original. New windows are sourced to match existing where the spec allows.

Do you handle the permits?

Yes — Brookline submits the permit set, coordinates inspections, and signs off. Permitting for additions is usually 4–8 weeks, depending on the municipality.
