About Our Connecticut ADU
Construction Services
At Peragallo Construction, we build custom Accessory Dwelling Units (ADUs) that provide practical space, long-term value, and seamless integration with your existing home. Based in Cheshire and family-operated for decades, we serve homeowners across Central and Southern Connecticut—including towns like Wallingford, Madison, Southington, and Middlebury.
Whether you're adding a private in-law suite, a detached guest house, or converting a garage into a rental-ready apartment, our team brings expert craftsmanship and dependable service from initial planning through final inspection.
ADU Options We Build Across Connecticut
Add space for extended family with an attached ADU that connects directly to your main home. Ideal for aging parents or live-in relatives, these suites offer privacy, accessibility, and a layout that flows with the rest of your property.

What Connecticut Homeowners Are Saying About Our ADU Work
"We worked with Peragallo Construction to build a detached ADU behind our home in Wallingford, and the experience was fantastic. From zoning guidance to the final inspection, their team made the entire process smooth and stress-free. The quality of the build is top-notch, and it blends beautifully with our main house.
