Why Orlando Homeowners Choose Karhan for Their Addition
Adding square footage is one of the biggest investments you can make. We make sure it's done right.
Seamless Integration
We match your existing roofline, siding, and interior finishes so the addition looks like it was always there.

Every addition is designed from scratch around your floor plan, lifestyle, and local building codes.
Permitted & Inspected
We handle all permits and inspections with Orange and Osceola county, so your project is code-compliant.
In-Law Suites
Multi-generational living is increasingly popular in Central Florida. We build private, comfortable suites.
Turnkey Project Management
One point of contact from design through final walkthrough — no juggling multiple contractors.
Bonus Room Additions in Orlando
A bonus room addition is the flexible-space version of a room addition — a media room, playroom, home office, gym, or guest space, added over the garage or as a rear addition, without committing the square footage to a specific bedroom count. In Orlando's market they're popular for the same reason in-law suites are: more usable house on the lot you already own.
Structurally, a bonus room is a real addition — foundation or over-garage framing, tie-in to the existing roofline, electrical, and HVAC extension — so it needs engineered plans and a building permit like any other addition. We handle both, take care of the permitting, and match the exterior so it reads as original to the house. For budget context, see our Orlando home addition cost guide — bonus rooms price like the room additions covered there, varying with size, structure, and finish level.

Home Addition FAQ — Orlando & Central Florida
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), bonus rooms, family room expansions, garage conversions, second-story additions, in-law suites, and covered patio enclosures throughout the Orlando metro area.
Yes — bonus rooms are one of our most requested addition types: flexible space for a media room, playroom, office, or guest area, built over the garage or as a rear addition. They're engineered and permitted like any other addition, and we match the roofline and exterior so the room looks original to the house.
