Cave Spring, Roanoke County
Cave Spring Garage to Studio Conversion
Turning a two-car garage into a light-filled workroom and guest suite
The garage behind this Cave Spring house had been storage for years. The framing was straight, the roof held, and the slab was sound, but there was no insulation, a single outlet near the door, and a floor that pitched toward the opening so water found its way in every spring. The owners wanted a room they could use in January, not just a place to park.
We kept the structure and rebuilt everything inside it. That decision shaped the whole job: no new foundation, no zoning variance, and the exterior stayed modest while the interior gained a workroom, a small kitchenette, and a guest corner with its own bed nook.
The problem
One outlet for a whole bay. No vapor barrier under the slab, so the floor stayed cold and damp. The door opening let in weather and road grit. Nothing about the space was usable past October.
What we did
Framed a new interior wall to separate the studio from a storage nook, sprayed closed-cell foam against the sheathing, then filled the stud bays with batt insulation. A subpanel was pulled from the main house to carry heat, lighting, and the kitchenette circuit.
The floor
The slab sloped about two inches across the bay. We ground the high side, poured a self-leveling underlayment, and let it cure before laying the new floor. That step alone took longer than the framing.
Windows, storage, and the small kitchenette
One of the two garage doors came out and a pair of tall windows went in, set high enough to keep the workbench clear and low enough to bring light across the floor. The remaining bay was closed off with a framed wall and a wide door, giving the owners a covered nook for bikes, mower, and garden tools.
The kitchenette is deliberately small: a sink, a short counter, and a compact fridge. It sits against the new interior wall so the plumbing could run back to the house side rather than under the slab.
What it took
- Permit review ran through the county with no variance, since the footprint never changed.
- Trades on site: an electrician for the subpanel, an insulation crew, a flooring installer, and a finish carpenter for the nook trim.
- Heating is a small wall unit sized for the insulated volume, not the original open bay.
- Exterior work stayed minimal: paint, new window trim, and a repaired threshold at the old door opening.

How it turned out
The room holds heat through the winter and stays dry after heavy rain. It works as a studio on weekdays and a guest space when family visits, and the storage nook keeps the tools out of the living area. Nothing about the outside of the garage announces the change, which was the point.
