Garages & Workshops

The shop you've been drawing on napkins since 2019

Detached garages, hobby shops, and heated workshops built to last — concrete floor, post-frame or steel structure, insulated where you want it heated, and doors sized for whatever you're actually parking in there. Revolve Construction builds them turnkey across the St. Louis metro and Southern Illinois.

Why homeowners and businesses trust Revolve

  • Sized around what goes inside

    We start with the lift height, the truck length, and the door width you need, then size the building — instead of selling you a stock kit and hoping the tailgate clears.

  • Heat-ready from the start

    Insulation, vapor barrier, and framing for the electric and gas runs get planned before the panels go on. Retrofitting a shop for heat costs three times what building it that way does.

  • Matched to the house

    Panel color, roof pitch, trim, and wainscot chosen so the shop looks like it belongs on the property — and doesn't tank the appraisal or upset the HOA.

What we offer

  • Detached Garages

    Two-, three-, and four-car detached garages with matching roof pitch and siding to complement the house.

  • Heated Hobby Shops

    Fully insulated shops with vapor barrier, liner panel, and framing ready for radiant or forced-air heat.

  • RV & Boat Storage

    14-ft and 16-ft overhead doors with the sidewall height and slab length to clear a fifth-wheel or a wake boat on a trailer.

  • Overhead & Walk Doors

    Insulated overhead doors, openers, service doors, and windows installed and trimmed as part of the build.

  • Concrete Floors & Aprons

    Reinforced floors with the apron, slope, and joint layout for vehicles and equipment.

  • Lofts & Mezzanines

    Storage lofts and mezzanines framed into the building instead of bolted on afterward.

Build the Shop You Will Still Want in Ten Years

Detached garages and workshops are the most common building we put up, and the most common regret is undersizing. Mobilization, permitting, site prep, and the fixed costs of a pour do not scale with square footage — going from a 24x30 to a 30x40 rarely costs proportionally more, and it is the difference between parking two vehicles and actually having a shop.

The other decision that matters more than people expect is sidewall height. A 10-foot wall gives you an 8-foot door and nothing above it. A 12-foot wall gets you a 10-foot door. A 14- to 16-foot wall gets you a two-post lift, an RV, or a storage mezzanine. Height is comparatively cheap at build time and effectively impossible to add later.

Heat-Ready From the Start

If there is any chance you will heat the shop — and in St. Louis, there is — build for it now. That means insulation and a vapor control layer designed into the assembly rather than stapled up later, framing and conduit paths planned for the electrical service, sleeves and stub-ups placed before the slab is poured, and a plan for where a heater, mini-split, or in-floor tubing will go.

Retrofitting a finished shop for heat means opening walls, pulling liner panel, running conduit through completed framing, and often adding a service. It routinely costs several times what including it in the original build would have. We ask about it during the estimate and price it as a visible line item so it is your decision rather than an assumption.

Condensation control matters even in unheated buildings. Bare steel panels sweat when warm humid air meets a cold underside, and that water drips on whatever you are storing. A condensation-control membrane or vapor barrier-backed insulation solves it cheaply during construction.

Making It Look Like It Belongs There

A shop that clashes with the house hurts curb appeal and, in a resale conversation, the appraisal. It also is the fastest way to a conversation with a subdivision trustee. We match roof pitch and panel color to the house, add wainscot, board-and-batten, or lap-siding accents where it makes sense, wrap windows and doors with proper trim, and detail the gutters so the shop reads as part of the property rather than as farm equipment parked next to it.

Because Revolve Construction is a roofing and siding company first, matching an existing home's shingle color, siding profile, or trim detail is routine work for us. We can also put a shingle or standing-seam roof on a post-frame building instead of screw-down panel where the neighborhood or the HOA expects it.

Frequently Asked Questions

1. How much does a detached metal garage cost in St. Louis?
As of 2026, a turnkey detached garage including site prep, a reinforced concrete slab, the post-frame structure, panels, trim, and an insulated overhead door generally runs $30 to $50 per square foot. A 24x30 building typically lands around $28,000 to $40,000; a 30x40 with a taller sidewall and two overhead doors is usually $45,000 to $70,000. Insulation, heat-ready framing, and matching siding finishes are priced as visible line items.
2. What sidewall height do I need for a car lift?
A standard two-post lift needs roughly 12 feet of clear height to raise a typical vehicle, so a 14-foot sidewall is the practical minimum and 16 feet is comfortable if you want to work under a truck or SUV. Also plan the slab: we thicken and reinforce the pad under a lift location before the pour rather than cutting it in later.
3. Do I need a permit for a detached garage?
In nearly every jurisdiction in the St. Louis area, yes — and setbacks, maximum accessory-structure size, and height limits vary by municipality and county. Subdivisions with trustees or an HOA often have additional rules about siding, roofing, and orientation. We pull the permit and check the restrictions before you order anything.
4. Can a metal garage match my house?
Yes. We match roof pitch and color, add wainscot or lap-siding accents, trim windows and doors, and can install shingle or standing-seam roofing on a post-frame structure instead of exposed-fastener panel. As a roofing and siding contractor, matching an existing home's finishes is standard work for us.
5. How big does a garage need to be for an RV?
Measure the rig, then add margin. Most Class A motorhomes and fifth-wheels need a 14-foot-wide by 14-foot-tall door, a 16-foot sidewall, and 40 to 45 feet of length with room to walk around it. Also plan the apron — a trailer or coach dropping off a slab lip at the door is a real problem.
6. Can you build a shop with a loft or mezzanine?
Yes. Storage lofts and mezzanines get engineered into the structure and the floor loads from the start, which is much stronger and cheaper than bolting a platform to a finished building. Tell us at estimate time and we will size the columns and trusses for it.
