Adding square footage is one of the biggest investments you can make. We make sure it's done right.
We match your existing roofline, siding, and interior finishes so the addition looks like it was always there.
A well-built addition adds significant resale value — often returning 60–80% of construction cost in equity.
Every addition is designed from scratch around your floor plan, lifestyle, and local building codes.
We handle all permits and inspections with Orange and Osceola county, so your project is code-compliant.
Multi-generational living is increasingly popular in Central Florida. We build private, comfortable suites.
One point of contact from design through final walkthrough — no juggling multiple contractors.
From your first call to final walkthrough, here's how we build home additions in Orlando.
We start with a free phone call to listen to your goals and discuss what's possible within your budget. If it's a good fit, we'll schedule an on-site walkthrough.
Our team develops architectural plans and submits permit applications to Orange, Osceola, or Seminole County as needed.
We excavate, pour the foundation, and frame the new space — all coordinated to minimize disruption to your daily life.
Mechanical, electrical, and plumbing rough-in work is completed and inspected before walls are closed.
Drywall, flooring, trim, paint, and fixtures are installed to match your existing home's aesthetic.
We walk through every inch of the addition with you, address any punch-list items, and hand you the keys to your new space.
Common questions from Orlando homeowners planning a home addition.
Home addition costs in Central Florida typically range from $150–$300 per square foot depending on complexity, finishes, and whether structural work is required. A 400 sq ft room addition might run $60,000–$120,000 fully finished. We can discuss details during our free phone consultation.
Most room additions take 3–6 months from permit approval to completion. Permitting alone can take 4–8 weeks in Orange County, so starting early is key. Second-story additions and in-law suites may take longer depending on scope.
Yes — all home additions require building permits in Florida. We handle the entire permitting process with your local county (Orange, Osceola, Seminole, etc.), including plan submission, inspections, and final certificate of occupancy.
Matching is a core part of our process. We carefully match rooflines, exterior siding, trim profiles, and interior finishes so the addition blends naturally with the rest of your home.
In most cases, yes — but it depends on your existing foundation and structural framing. We conduct a structural assessment as part of our consultation to determine feasibility and cost.
We build room additions (bedrooms, home offices, sunrooms), family room expansions, garage conversions, second-story additions, in-law suites, and covered patio enclosures throughout the Orlando metro area.
