Golf Simulator Shed: The Ultimate Backyard Build Guide

---

Your garage is fine. Your basement works. But you don’t want fine. You want your own building.

A dedicated golf simulator shed is the endgame. It’s the room you build specifically for golf, not the room you retrofit because the car didn’t need it anymore. It’s the difference between asking permission and building the thing you want. If you have the yard space and the budget, skip the garage conversation entirely. Build the shed.

I’m not kidding. This is the best possible room for a golf simulator, and it’s not close. Let me tell you why, exactly what size to get, and how to not screw it up.

Why a Shed Beats Everything

Three reasons the shed wins.

Separation. The garage is still attached to the house. The basement is under the house. The spare bedroom is IN the house. A shed is in the backyard. You walk outside, you open the door, you’re in golf world. You close the door behind you and the rest of your life doesn’t exist for two hours. That psychological separation is worth more than any square footage.

No sharing. The garage has a car in it. The basement has the laundry and all the Christmas decorations. The spare bedroom has — well, it’s supposed to be an office. Your shed has one job. Golf. Nobody walks into your shed and asks why the car is still outside. Nobody moves your clubs to fold laundry. The shed is yours.

Leave it up. Garage sim owners take down the screen so the car fits. Basement sim owners worry about moisture. Spare bedroom sim owners look at the PC and wonder if the kids need it for homework. Shed owners lock the door and walk away. The screen stays. The mat stays. The clubs stay. It’s always ready.

Sound isolation. This matters more than you think. A driver swing in a garage rattles the whole house. A driver swing in a shed stays in the shed. You can hit balls at 10 PM without your wife Googling divorce lawyers. The shed is 40 feet from the house. By the time the sound reaches her, it’s background noise.

How Big Does the Shed Need to Be?

Here’s where most people screw up. They buy a shed that’s big enough for storage and discover it’s not big enough for golf.

Let me be specific.

Minimum: 10x12 feet. The 8x10 everyone recommends online? Too small. You can hit a 7-iron in an 8x10. You cannot hit a driver. You cannot have a full enclosure. You cannot have a simulator. You have a hitting net pointed at the wall with 6 inches of clearance on each side. If that’s your budget, fine. But don’t call it a simulator shed. It’s a hitting shed.

Recommended: 10x14 to 10x16. This is the sweet spot. 10 feet wide gives you room for a 9-foot wide enclosure with a few inches of breathing room on each side. 14-16 feet of depth gives you ball-to-screen distance (8-10 feet), room behind the ball to swing a driver (4 feet), and space for you to stand without your back against the wall. This is the size I’d buy if I were building today.

Ideal: 12x16 to 12x20. 12 feet wide means you can fit a 10-foot wide enclosure, side tables for your launch monitor and laptop, and a small chair or stool. 16-20 feet of depth gives you the full simulator experience plus some room for a mini-fridge, a stool, and maybe a small heater in the corner. At this size, the shed isn’t just a sim room — it’s a golf building.

Do not buy an 8x10 thinking you’ll “make it work.” You won’t. You’ll be back on Reddit in three months asking how to add 2 feet of depth to a shed. You can’t. Get the right size the first time.

Shed Types: What to Buy

You have three options. Two of them are good. One is a trap.

Prefab shed from a big box store (the good budget option). Home Depot, Lowe’s, Tuff Shed — these all sell pre-built or kit sheds in standard sizes. A 10x12 Tuff Shed runs about $2,500-4,000 delivered and installed. A 12x16 runs $5,000-7,000. These are wood-framed, have a floor, have a door, and have windows. You can insulate and finish them yourself. This is the right move for 80% of people.

Custom-built shed (the ideal option). You hire a contractor or a shed company to build exactly what you want. You specify the size, the roof pitch, the window placement, the door location (center or offset — get offset, you’ll thank me when the sim goes in), and the electrical drop. This costs more — $8,000-15,000 for a finished 12x16 — but you get exactly what you need. No compromises. No “well, the window ended up right where the impact screen goes.”

One of those metal storage sheds (the trap). Those $500-1,000 metal sheds from Costco? Don’t. They leak condensation, they’re impossible to insulate properly, they look terrible, and the roof isn’t strong enough to mount a projector from. I’ve seen exactly one successful sim shed built with a metal shed and it involved so much re-engineering that the guy spent more on modifications than a Tuff Shed would have cost. Buy wood.

The Build: Step by Step

Here’s the order. Follow it.

1. Location and Foundation

Put the shed on flat ground. If your yard slopes, level it before the shed arrives. A 4-6 inch gravel base with pressure-treated skids or a concrete slab — your choice.

Concrete slab is better for a sim shed. It’s dead flat, it doesn’t move, and it handles the weight of an enclosure + mat + person swinging without any flex. Budget $500-1,000 for a 10x12 slab if you DIY, $1,500-2,500 if you hire it out.

Gravel base is fine for a budget build. Just lay landscape fabric, 4 inches of crushed gravel, tamp it flat, and put the shed on skids. It will settle over time. You’ll feel it in your stance. But it works.

Here’s the thing nobody tells you: put the shed door on the short side, not the long side. If you have a 10x14 shed, the 10-foot wall is the one with the door. The 14-foot depth becomes your hitting axis. This is obvious once you think about it, but half the sheds I see online have the door on the long side and the owner is hitting into a 10-foot depth with no room to swing. Don’t be that guy.

2. Electrical

You need power. Run a buried conduit from your house panel to the shed. Hire an electrician. This is not a DIY job unless you really know what you’re doing.

Minimum: one 20-amp circuit. That runs lights, a launch monitor, a PC, and a small heater or fan. If you’re adding a projector, a mini-split AC, and a sound system, run two 20-amp circuits. Budget $500-1,500 for the electrician depending on distance from the house.

Put outlets on every wall. Code requires one per wall in a finished space, but put extras where the sim goes — one for the launch monitor, one for the PC, one for the projector at the ceiling, one for the subwoofer. Outlets cost $20. Running them after the drywall is on costs $200.

3. Insulation

Insulate everything. Walls, ceiling, floor. This is a small building — the insulation cost is maybe $200-400. Do not skip it.

R-13 in the walls. R-19 in the ceiling. Foam board under the floor if you’re on a gravel base. The shed will be 20°F warmer in winter and 20°F cooler in summer just from insulation. It’s the cheapest comfort upgrade you can make.

If you’re in a cold climate (below freezing for more than a month), get the walls spray-foamed. It’s more expensive — $1,000-2,000 for a 10x12 — but it seals air gaps and gives you better R-value per inch. In a small shed, every inch of interior space matters.

4. Heating and Cooling

The insulated shed now needs temperature control. You have three options:

Electric infrared heater ($150-300). Mount it on the wall, point it at the hitting area, and it warms you up in 5 minutes. This is what most people use. It works fine for a shed that’s only occupied when you’re hitting balls. Don’t use it to maintain temperature when you’re not there — use a thermostat-controlled space heater with frost protection ($40 at any hardware store) to keep the shed above 40°F so your launch monitor doesn’t freeze.

Mini-split heat pump ($1,000-2,500 installed). This is the premium option. Heats and cools, maintains any temperature year-round, and runs efficiently. If you’re in a climate with real summers or real winters, this is the move. A mini-split in a correctly sized shed (10x12 or 12x16) will keep it at 68°F no matter what’s happening outside. It costs more upfront but it’s the only option that gives you true climate control.

Propane heater ($100-200). Don’t. Ventilation is a nightmare in a small space, moisture is bad for electronics, and the smell makes the shed feel like a hunting cabin. If you want propane, build a bigger shed with proper ventilation and an exhaust fan. Otherwise, go electric.

See our garage heating and cooling guide for the full breakdown — most of it applies to sheds too.

5. Flooring

The shed floor needs three layers.

Bottom layer: a vapor barrier (6 mil poly sheeting) between the subfloor and the joists. This prevents ground moisture from rotting your floor.

Middle layer: the plywood subfloor that comes with the shed. If you went with concrete, skip to the top layer.

Top layer: interlocking EVA foam tiles ($1-2 per square foot). Put them over the entire floor. They cushion your joints, protect dropped golf balls from damaging the subfloor, and give the space a finished look. Put your hitting mat directly on top of the foam.

Do not carpet the shed floor. Carpet holds moisture, collects dust, and shows every scuff mark from your shoes. Foam tiles are clean, replaceable, and you can hose them off if they get dirty.

6. Interior Finish

Here’s where you decide how nice you want it.

Budget: Leave the studs exposed. Paint them flat black. Hang your enclosure. Done. It’s a shed. It doesn’t need drywall. The black paint makes the studs disappear when the projector is on. Total cost: $30 for paint.

Mid: Drywall the walls, paint them white or light gray. Leave the ceiling open (exposed trusses + black paint). The white walls reflect projector light and make the space feel bigger. The black ceiling disappears. Total cost: $200-400 for drywall, mud, tape, and paint.

Premium: Drywall everything, including the ceiling. Paint the walls a dark color like charcoal or navy — it makes the projected image pop. Install baseboards. Add crown molding if you’re fancy. Total cost: $500-800.

I’d go mid for a first build. You can always finish the ceiling later.

What Goes Inside

You need the same sim gear as any other room. Let me be specific about what works best in a shed.

Launch monitor: Any camera-based unit works perfectly in a shed because you control the lighting. The SkyTrak+ ($1,995) is the no-brainer for most shed builds. The Uneekor EYE XO ($5,999) ceiling-mount is the dream — no floor unit, instant lefty switching, and the shed was designed around it anyway. The Garmin R10 ($599) works too if you’re budget-conscious, but radar units need more depth (14+ feet ball to net) and sheds shorter than that won’t have enough ball flight for accurate spin readings.

Enclosure: Carl’s Place DIY kit. Same answer as every other room. Get the premium impact screen. Size depends on your shed width — a 10-foot wide shed fits a 9-foot wide enclosure with breathing room. A 12-foot wide shed fits a 10-foot wide enclosure. See our full enclosure build guide → for a step-by-step walkthrough.

Mat: Dual-pad setup. Stance mat + replaceable hitting strip. Fiberbuilt or Carl’s Place. Budget $300-500.

Projector: Short-throw, minimum 3,000 lumens. Mount it on a shelf or bracket attached to the ceiling trusses or back wall. In a shed, the projector mount has to be solid — sheds flex more than house walls, and a loose mount means a blurry image. Use a heavy-duty mount bolted into wood, not drywall anchors.

See our DIY build guide for the full walkthrough on installation, and our space requirements guide for the dimensional checklist.

Permits: The Thing Nobody Talks About

You need a permit for an electrical shed. You might need a permit for the shed itself.

Every jurisdiction is different, but the rule of thumb is: if the shed is over 120 square feet (10x12), most places require a building permit. If you run electricity, you need an electrical permit regardless of size. If you’re in an HOA, you might need approval regardless of anything else.

The permit costs $50-200. The fine for building without one costs $500-5,000 plus the cost of tearing it down if a neighbor complains. Get the permit. It’s paperwork. It’s not scary.

The Full Cost Breakdown

Here’s what a shed sim actually costs, assuming you DIY the shed finishing and sim installation:

The shed itself:

• 10x12 Tuff Shed delivered: $3,000
• Gravel base and leveling: $300
• Electrical (electrician): $1,000
• Insulation: $300
• Drywall + paint: $300
• Heater: $200
• Foam floor tiles: $150
• Shed subtotal: ~$5,250

The simulator:

• Launch monitor (SkyTrak+): $1,995
• Carl’s Place 9x8 enclosure: $550
• Hitting mat (dual-pad): $400
• Short-throw projector: $600
• Budget PC: $400
• Hardware + cables: $100
• Sim subtotal: ~$4,045

Total: ~$9,300

You can do it cheaper — $5,500 total with a Garmin R10, a net instead of an enclosure, and a heater-only approach. You can do it more expensive — $15,000+ with a 12x16 custom shed, Uneekor EYE XO, 4K projector, and mini-split HVAC.

The $9,300 number is the sweet spot. A proper shed build with proper sim gear that you’ll use for the next 10 years. No compromises. No “I’ll upgrade later” regret.

The Mistake Everyone Makes

They try to build the sim into an existing garden shed.

A 6x8 storage shed from the previous owner is not a sim shed. It’s a shed where you store stuff. The ceiling is 6 feet tall. The floor is rotted. The door is 3 feet wide. You cannot make this work for golf. I have seen people try. It ends with them posting on Reddit asking if they can cut a hole in the roof for more ceiling height. (You can’t. The roof is structural.)

Start with the right building. Don’t retrofit the wrong one.

Your Next Move

Measure your yard. 10x14 minimum. Flat ground. Accessible from the house. If you’ve got it, you’ve got the best possible site for a golf simulator.

Then call Tuff Shed or a local shed builder. Get a quote for a 10x14 or 12x16 with a door on the short side. While they’re building it, order the sim gear.

The shed takes 2-4 weeks. The sim takes a weekend. In five weeks from today, you can walk out your back door and hit golf balls in a building that exists for nothing else.

That’s the move. Do it.
