Garage Conversions in Lewisville, TX
A garage is the cheapest square footage you already own. Converting it well means more than drywall: the slab usually sits lower than the house, the walls and door opening need insulation and framing, the room needs its own heating and cooling, and the city and HOA may have parking rules. We plan the conversion so it reads as part of the house, inside and out.

What it costs
| Scope | Typical range | Includes |
|---|---|---|
| Basic conversion (office, gym) | $25,000–$45,000 | insulated, conditioned, finished |
| Bedroom or suite with bath | $45,000–$90,000+ | adds plumbing, egress, closet |
These ranges are for orientation, not a quote. Every house is different; your price is written after we see the work, before anything starts.
Adding a bathroom is the biggest cost jump because it means cutting the slab for drain lines. The exterior is the other variable — infilling the door opening with brick to match costs more than siding, but it's what makes a conversion look original.

Garage Conversions questions — Lewisville, TX
How much does a garage conversion cost in Lewisville, TX?
A basic conversion to an office or gym typically runs $25,000–$45,000, and a bedroom or suite with a bathroom $45,000–$90,000 or more. These are typical Dallas–Fort Worth ranges; your price is written after we look at the garage.
Do I need a permit to convert my garage in Lewisville?
Generally yes — converting a garage changes how the space is used and usually adds electrical and HVAC. Some cities and HOAs also have off-street parking requirements. We check Lewisville's rules and your deed restrictions before quoting.
Does converting the garage hurt resale value?
It depends on the neighborhood. Where most buyers expect a two-car garage, it can narrow your buyer pool; where living space is the constraint, it usually adds value. We'll give you a straight opinion for your street.
Can we keep a working garage door instead?
Yes. For a gym or workshop, some owners keep an insulated garage door so the space can still open up. Our sister company, Pebblegrove Garage Doors, installs insulated doors if that's the better fit.
