Detached Building
A new, free-standing structure built on your property — slab, shell, utilities, and finish, with a simulator bay at its center. Not a kit dropped in the yard and not a converted shed: a real building, designed and built from the ground up by the crew that framed and finished our own five-bay club.
This is the version where you don't have the interior space — or you want the bay separate from the house entirely. We pour the foundation, frame and finish the shell to match your home, run power, climate, and data out to it, and build the room inside. It can be a single-bay golf building, or a multi-use accessory building — a lounge, bar, office, or guest space with the bay as the centerpiece. Site review, permits, build, calibration. That's the order, and we handle all of it.

Why a Building of Its Own
Sometimes there's no basement with the ceiling height, no garage to give up, and no remodel that gets you the space — but there's a spot on the property where a building could go. That's when a detached structure makes sense. The catch is that the internet's answer to it is a prefab kit or a metal shed: a bare shell with no power, no insulation, no heat, and no permit. In Kansas City that's a room you can use maybe four months a year. A building you actually use means a slab, a real shell, utilities run out to it, and climate inside — and that's construction, which is the part the kit can't sell you.
A kit gives you a box in the yard. We give you a building.

A detached building, built from the slab up
Here's where this fits against the rest of what we do, so you can place yourself: this page is a new, detached structure built from the foundation up. If the work is inside your existing house, that's a custom design + build . If it's an existing garage, that's a garage conversion . If the house is still being built, it's new construction integration . A detached building is the right call when none of those have the space — or when you want the bay as its own structure.
What's Included
A detached building is the whole job — the structure and the room inside it. Here's the order it runs in, from the site review to the day we calibrate.
Before a shovel moves, we check the things that decide whether the building can go where you want it: setbacks, lot coverage, the max size for an accessory structure, and any HOA or architectural review. Rules vary by jurisdiction — we frame it honestly and handle the permitting.
A building lives and dies on what it sits on. Depending on the site and the design, that's a poured slab on grade, a frost-protected footing, or a stem-wall foundation — sized for the structure and the climate, with the simulator's flat, level floor planned in from the first pour.
Framing, roof, windows and doors, siding and trim — built and finished to match the main house so it reads as part of the property, not a bolt-on. Ceiling height is framed for full driver clearance from the start, because you can't add it later.
This is the part a kit can't touch: running a dedicated power feed, HVAC or a mini-split for year-round climate, and hard-wired data out to a separate building. Trenching, conduit, and the licensed trades to do it right — so the room is comfortable and connected in January, not just July.
Insulation, sound control, lighting, and finish inside — then the bay itself: enclosure, screen, projector, mat and turf, installed and squared. We calibrate last and don't leave until the numbers are right and the picture is true.
A detached building is the biggest residential version of what we do, so it isn't always the right one. If you've got a basement with the height, or a garage to give up, finishing space you already own is usually the cheaper path — a custom design + build or a garage conversion . Same crew, same standards, smaller job — and we'll tell you when that's the smarter move.
Construction First
Most simulator companies are AV people who picked up construction on the job. Ask one to build you a whole structure — foundation, framing, roof, a power feed trenched across the yard — and the conversation ends. We're the reverse. The father has been framing, finishing, and building Kansas City homes since 1995, spec and custom, from the footings up. A detached building is squarely our trade, not the part we sub to a stranger and hope.
That doesn't mean one person does everything. One team is accountable start to finish: we self-perform the construction craft — foundation prep, framing, finish, the simulator-specific work — and we manage the licensed trades for electrical, HVAC, and anything code requires. One company stands behind the whole structure. We build across the Kansas City metro , Columbia, and the Lake of the Ozarks, and the showroom is right here in south KC.
A detached building is the top of the residential ladder. If your space is already there — a basement, a garage, a room under construction — you may not need all of this, and we'll say so. We'd rather scope it right than sell you a building you didn't need.
Investment
A detached building is the top residential tier — you're paying for a whole new structure, so the ranges sit above an interior build. The real number comes after a site visit, itemized with nothing buried. Most detached projects land in one of these three.
$80k–$120k
Single-Bay Accessory Building
A right-sized stand-alone structure for one bay — slab, shell, utilities run out, insulation, and a clean finished interior. A purpose-built golf building, not a multi-use space.
Most common
$120k–$200k
Multi-Use Building
A larger building that's a lounge, bar, office, or guest space with the bay as its centerpiece — more square footage, more finish, and the climate and plumbing a real room needs.
$200k+
Top-End / Livable Build
A fully finished building with the higher-end carpentry and equipment — and, if you want living quarters, the path toward an ADU. The structure becomes part of the property, not an outbuilding.
Those ranges cover the building — foundation, shell, utilities, and finish. The launch monitor is a separate line, settled last, after the room and the goal are clear: a strong system starts around $4k and runs past $40k at the top, with a Mevo+ near $1k before goal-based software. That spread says more about who spent what on advertising than about which unit reads your swing more accurately. Our honest launch monitor comparison breaks down the real differences, and financing in Kansas City can stretch the whole project over time.

Before You Commit
A detached building is a big construction decision, and renderings only tell you so much. The things that separate a good room from a great one — the trim, the screen tension, the lighting, how square it all sits — you can only judge in person. The bays at our showroom were built by the same crew that would build yours, so walking them tells you exactly what to expect.

FAQ
Almost certainly yes — a new structure is a permitted build, and that's a good thing, because it means it's done to code and won't bite you at resale. The rules that decide where and how big it can be — setbacks from property lines, lot coverage limits, the maximum size for an accessory structure, and any HOA or architectural review — vary by jurisdiction across the Kansas City metro.
We do the site and zoning review up front and pull the permits as part of the job. If a setback or coverage rule changes what's possible, you hear it before you spend money, not after.
Not by default. As we build it, a detached golf simulator building is a non-dwelling accessory structure — a building with a bay, a lounge, maybe a bar or office, but no kitchen or full bathroom and no one living in it. That keeps the permitting and the cost simpler.
If you do want livable space — a guest suite or true living quarters — that's an ADU, which is a different category with its own rules, plumbing, and review. We can build toward that too; we'll just scope it honestly, because it changes the project.
This is the real differentiator versus a kit, and it's ordinary work for a construction company. We run a dedicated power feed from the house or panel — trenched and conduited to code — size the service for the equipment and the climate system, and bring in a licensed electrician to make the connections.
For heat and AC, a mini-split or a small dedicated HVAC system keeps the building comfortable year-round, which matters in a place that swings from January to August. We run data the same way, hard-wired, so the simulator isn't fighting a weak signal from across the yard.
More, and it should — you're paying for a whole new structure, not finishing space you already own. A detached building starts around $80k for a single-bay structure and climbs from there with size, finish, and use, because the slab, shell, roof, and utilities are all new. Finishing an existing basement or converting a garage is usually the cheaper path to a bay.
You build detached when you don't have the interior space, want it separate from the house, or want a building that's its own thing. If the goal is just the cheapest way to a good bay, we'll point you at a basement or garage instead — that's the honest answer.
That's often the best reason to build one. Because it's a building of its own, it can be a lounge, a bar, a home office, or a guest space with the simulator as the centerpiece — designed around how you'd actually use it, not just where the screen goes.
A multi-use building needs more square footage, more finish, and usually real climate and a half-bath, so it costs more than a bare single-bay structure. But you end up with a room you live in, not a shed you visit to hit balls.

A detached building is for when the space isn't already inside the house. If you've got the room, one of these is the better starting point:
