More space, matched to your home and your local code

Adding on is the most structural work a home can undergo — foundation, framing, roofline, and tie-ins all have to be engineered and permitted correctly. We manage the whole process, from feasibility and design through permits and final finishes.

Additions and accessory dwelling units (ADUs) are handled differently by each jurisdiction — the City of Oviedo, unincorporated Seminole County, and the City of Orlando each set their own rules. We build to what actually applies to your Windermere lot.

Windermere, Orange County

What a home addition in Windermere involves

We work throughout Windermere — from Isleworth and Keene's Pointe to Windermere Downs, Butler Bay, The Willows. Windermere is an affluent Butler Chain of Lakes community of large custom estates, and it sits in Orange County, part of the Greater Orlando area we cover from our base in Oviedo.

Permitting for a Windermere home addition goes through Town of Windermere / Orange County. Not every Windermere address is inside the city limits — some are unincorporated Orange County, and that changes which department reviews your plans. We confirm the jurisdiction for your exact address before anything gets filed.

Alongside Windermere, we regularly take on work in nearby Orange County communities including Orlando, Winter Park, Maitland and Baldwin Park.

Every Windermere home addition we take on is run by the same licensed general contractor (CGC1539321) that pulls the permit — so there is one point of accountability from the first walkthrough in Isleworth or Keene's Pointe through final inspection with Town of Windermere / Orange County.

Additions & ADUs FAQ
