Home Additions & ADUs in The Colony
Families in The Colony tend to love where they live — the lake, the schools, Grandscape, and the trails — and would rather add on than start over somewhere new. That is especially true in the established neighborhoods off Main Street and along Stewart Peninsula, where 1980s and '90s homes sit on generous lots but were built with smaller footprints than today's households need. A well-planned addition or a detached ADU gives you the extra room without giving up your address.
Room additions, second stories, and ADUs
We design and build the full range: primary-suite additions, expanded kitchens and great rooms, bonus rooms over the garage, sunrooms that face the water, and detached accessory dwelling units for aging parents, adult kids, a home office, or guests. Every addition is engineered to tie into your existing roofline, foundation, and structure so it reads as part of the original house — not a box bolted onto the back. As a design-build team, we handle the design, the structural engineering, and the construction under one roof.
Permitting an addition in The Colony
An addition is real building work, and The Colony reviews it accordingly. Residential building permit applications go to the city's Building Inspections office at 6053 Main Street as an emailed PDF — the eTRAKiT portal is for looking up permits and scheduling inspections, but it cannot accept the application itself, which trips up contractors who do not work the city often. We build in the roughly 10-15 business-day plan review window and the $50 application fee, and we design to the 2024 ICC codes and 2023 NEC the city adopted in 2025. Setbacks, easements, and lot coverage all get checked before we ever break ground.
