We typically reply the same business day.
Right Image Builders is a licensed and insured Florida general contractor (CGC1539321) in Oviedo, building home additions and ADUs across Longwood and Seminole County. Room additions, second stories, in-law suites, and garage conversions — structural engineering, permitting, and construction under one contract. 4.9★, 433+ projects.
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 Longwood lot.
Add a bedroom, primary suite, or great-room bump-out with a foundation and roofline that match the existing home.
Build up when you can't build out — engineered for the existing structure and Florida wind loads.
Detached or attached accessory units and garage conversions for multigenerational living or a home office, built to local code.
We coordinate the structural engineering, permitting, and any HOA/ARB review so the addition is legal and lasting.
We work throughout Longwood — from Sweetwater Oaks and Wekiva Cove to Sabal Point, The Springs, Alaqua. Longwood is an established Seminole County city with mature tree canopy and a historic core, and it sits in Seminole County, part of the Greater Orlando area we cover from our base in Oviedo.
Permitting for a Longwood home addition goes through City of Longwood Building Division. Parts of Longwood carry historic-district review, so anything that changes the look of the house from the street can need an extra approval before a permit is issued. We build that step into the schedule rather than discovering it late.
Alongside Longwood, we regularly take on work in nearby Seminole County communities including Winter Springs, Casselberry, Lake Mary and Sanford.
Every Longwood 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 Sweetwater Oaks or Wekiva Cove through final inspection with City of Longwood Building Division.
Longwood is an established Seminole County city with mature tree canopy and a historic core. We cover the whole city — Sweetwater Oaks, Wekiva Cove, Sabal Point, The Springs, Alaqua — and the surrounding Seminole County area, with plans filed through City of Longwood Building Division.
