Home Additions & Expansions

Seamless integration of new living space into existing structures: second stories, wings, and bump-outs.

The approach

The hardest part of an addition is making it look effortless, as if the new square footage was always part of the home. We match rooflines, finishes, and proportions so the seam disappears.

What's included

  • Second-story additions
  • Ground-floor expansions & bump-outs
  • Garage conversions & new garages
  • Roofline & structural tie-ins
  • Foundation underpinning & reinforcement
  • Exterior finish matching
Why it matters

Built the right way

01

Invisible transitions

Careful detailing at the connection between old and new so the addition reads as original construction.

02

Structure-first thinking

We engineer the tie-in to the existing foundation and framing before a single new wall goes up.

03

Live-in friendly

Phased construction keeps the rest of the home usable while the new space takes shape.
