Home additions that respect the original

The worst compliment an addition can get is “nice addition.” Ours aim for “wait, which part is new?”

We design additions from the street in: matching eave lines, window proportions, and siding reveals so the new volume reads as original. Inside, the seam disappears because the trim comes out of our shop matched to your existing profiles.

Structural engineering, zoning and lakefront setbacks, and the City of Madison permit process are all handled in-house. You will see the massing in 3D from your own yard’s vantage points before anything is final.

How it works

How a project runs

  1. 01

    Walk the house

    We meet at your home, talk scope and budget honestly, and tell you on the spot if we are not the right fit.

  2. 02

    Design in the shop

    Drawings, 3D previews, and materials you can hold, in the studio attached to our workshop. Ends with a fixed price.

  3. 03

    Build it once

    A posted calendar, a dust wall, a broom-clean site every night, and cabinetry arriving from a mile away instead of a freight dock.

  4. 04

    Come back in winter

    Final walkthrough, then the Second Winter visit 14 months later to make right anything the seasons moved.

Good to know
