Home Additions in Windermere, FL

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 rules change between each city and the unincorporated parts of Seminole, Orange and Osceola counties. We build to what actually applies to your Windermere lot.

Windermere means two things: the small Town of Windermere on the Butler Chain of Lakes, with sand roads and older lakefront homes, and the gated estate communities around it — Isleworth, Keene’s Pointe, Butler Bay, The Willows — which are mostly unincorporated Orange County with their own architectural review. For additions and ADUs, it means confirming the zoning, setbacks and any HOA or architectural review for your specific lot before design starts.

Typical time: about 3–5 months from permit to finish for a room addition; second stories and ADUs take longer. The stages are the same for every addition we build across Greater Orlando; what changes is the size of the job and the review time at your building department.

1. Site visit and feasibility — we measure, check the slab, roof, electrical panel and plumbing, and confirm the zoning setbacks and any HOA or architectural review for your lot.
2. Design — a floor plan and elevations matched to the house, then a written, itemised estimate.
3. Structural engineering — sealed drawings for the foundation, the roof tie-in and the wind design for your address, plus energy calculations.
4. Permit review — the set goes to Town of Windermere / Orange County; we answer any review comments, and the written schedule you get with the estimate builds in that turnaround.
5. Construction — foundation, framing, the roof tie-in and dry-in, then the trades, insulation, drywall and finishes.
6. Inspections and close-out — every inspection scheduled by us, the permit closed, and a final walkthrough with you.
