PSL Custom Wine Cellar is a Port St. Lucie wine cellar builder handling wine cellar construction for restaurants, hotels and homes, from bare studs to the last bottle on the rack. Most jobs start with a space that was never meant to hold wine, like a garage corner, a dry storage room behind a kitchen or a closet against a sun-baked exterior wall.
Every build covers the parts guests never see:
That's how a cellar that looks great in April still holds 55°F in August. After 60+ restaurant and commercial cellars on the Treasure Coast, the crew knows how hard a busy wine room gets used. Builds run across Port St. Lucie, Fort Pierce, Hobe Sound and Vero Beach, and the first site visit is free.

These design concepts show what wine cellar construction looks like when the room starts out somewhere less than ideal, from a hot garage to a busy restaurant.

DESIGN CONCEPT · TESORO
A Tesoro homeowner wanted a real cellar but had no spare room, only a deep corner of a 2-car garage that hit 95°F most summer afternoons. The build framed a 6 by 8 foot room with 2x6 walls, filled them with closed-cell foam, added a vapor barrier and hung an insulated exterior-grade door. A ducted split system vents outside the garage, and the finished room holds about 600 bottles at 55°F.
Estimated budget: $34,000
Estimated timeline: 2 weeks of framing and insulation, 1 week of racking and cooling

DESIGN CONCEPT · HUTCHINSON ISLAND
This oceanfront condo had a walk-in closet against an exterior wall that took the full afternoon sun, and the building rules ruled out any noisy equipment. The closet was stripped to the studs, re-insulated and sealed, then fitted with a whisper-quiet ductless unit and redwood racking. It now stores about 220 bottles without a peep reaching the bedroom next door.
Estimated budget: $14,500
Estimated timeline: 1 week of prep and approvals, 5 days on site

DESIGN CONCEPT · SANDPIPER BAY
A restaurant near Sandpiper Bay was keeping its wine in a dry storage room that drifted past 80°F during dinner service. The room was rebuilt with insulated walls, a self-closing insulated door and a keypad lock, then lined with heavy-duty metal racking. A ducted cooling system keeps 1,200 bottles steady even with staff walking in and out all night.
Estimated budget: $48,000
Estimated timeline: 3 weeks of build-out, final install over 2 nights after closing

01
Wine cellar construction starts with the shell. We frame the walls to take closed-cell insulation, run a vapor barrier on the warm side and seal every outlet and seam so humid Port St. Lucie air stays out.

02
Cooling units are sized to the room's real heat load, then installed as through-wall, ducted or ductless systems depending on noise and space. Every system runs until the cellar holds 55°F and steady humidity.

03
Racks go in once the shell is sealed, anchored to the framing and built in mahogany, redwood or powder-coated metal. Layouts mix single slots, diamond bins and display shelves around the collection.

04
Glass walls need insulated panels, tight gaskets and a door that seals on every side to stop condensation. We frame and install frameless enclosures that keep the collection on show without losing temperature.

05
Closets, under-stair spaces, garages and spare rooms can all become working cellars. Remodels often add insulation, a sealed door or a new cooling unit to an older cellar that never held temperature.

06
Restaurants, clubs and hotels need cellars that handle daily traffic. Builds include heavy-duty racking, lockable insulated doors and cooling that keeps up with the door opening all through service.
Closet and under-stair builds usually run $8,500 to $18,000, glass wine rooms $20,000 to $60,000 and full walk-ins $25,000 to $70,000. Framing, cooling and racking material drive most of the price.
Most closet and under-stair cellars are built in 1 to 2 weeks, while walk-ins and commercial cellars usually take 3 to 6 weeks depending on framing, glass and cooling.
Walls get a 6-mil vapor barrier on the warm side with closed-cell or rigid foam insulation behind it, finished with an exterior-grade insulated door. Racking is usually mahogany, walnut or powder-coated metal.
Most builds use WhisperKOOL or CellarPro units installed by EPA 608 certified techs. Closets get self-contained units, while larger rooms get ducted or split systems that move the compressor outside the cellar.
Yes. Each project carries a 2-year workmanship warranty on the build, plus the manufacturer warranty on the cooling unit.
Projects that add electrical circuits, structural changes or new cooling equipment usually need a permit from the City of Port St. Lucie Building Department, so permit needs are checked during the first site visit.
