Additions in Middletown

What additions projects look like in Middletown

The Middletown homes we work in are mostly 2000s–2020s, typically new construction colonials, transitional, and large-lot two-stories. We've completed projects across Whitehall, Bayberry, and the Westown area.

Middletown's newer construction means most of our work is post-builder customization, finished basements, sunrooms, primary bath upgrades, and outdoor living spaces.
