The Short Answer
Net+mat: 30min. Full enclosure: weekend. Full rebuild: 2-4 weeks. Real timelines from guys who've done it. Plan realistically.
Quick answer: A basic net-and-mat setup takes 30 minutes. A full enclosure with impact screen, projector mount, and turf — figure a weekend. A complete garage rebuild with framing, electrical, HVAC, and soundproofing — 2 to 4 weeks. Most people overestimate how fast they’ll finish and underestimate how many trips to Home Depot it takes. Budget 2x the time you think you need.
You’ve made it past the cost wall. You know it’s not $20,000. You’ve measured the garage. You’ve even had the conversation with your wife.
Now there’s a new question rattling around in your head:
How long is this going to take?
Not “how long to order.” How long to build. How long from “box on the driveway” to “first ball in the screen.” Because you’re not a contractor. You don’t own a stud finder. Your last DIY project involved a Billy bookcase and a lot of cursing.
Good news: the answer is shorter than you think.
30 Minutes — The Net + Mat Setup
This is the real answer for most guys starting out.
A launch monitor, a net, and a mat. That’s it. You open the box, you unfold the net, you put the mat on the floor, you turn on the launch monitor. If it takes you longer than half an hour, you’re either grilling something or arguing with the dog.
What you’re building: A hitting bay. No screen. No projector. No enclosure. You hit balls into a net, your phone or tablet shows you the data.
One guy on r/GolfSimulator:
“Got the Spornia net, Garmin R10, and a Fiberbuilt mat. From UPS drop to first swing: 22 minutes. And I stopped to pee.”
22 minutes. That’s probably faster than your last Amazon return.
What you need:
- A net that pops open (Spornia SPG-7, Rukket, Net Return)
- A launch monitor (Garmin R10, Rapsodo MLM2Pro)
- A mat (Fiberbuilt strip or whatever you’ve got)
- Your phone or tablet
Everything arrives Thursday. You set it up Saturday morning while your coffee’s brewing. You’re hitting balls before the second cup.
One Weekend — The Full Enclosure Build
This is where most guys land after they’ve proved the concept. You want a real impact screen. A projector. An enclosure that catches the ball and looks like a real simulator, not a science experiment.
The build: Carl’s Place DIY enclosure kit. Pre-cut screen, pre-sewn shroud, corner fittings, EMT conduit for the frame. You run the conduit, you tension the screen, you hang the shroud, you mount the projector.
Real timeline from the forums:
“Bought the Carl’s 10x7 DIY kit. Saturday morning I ran the conduit and mounted the screen. Saturday afternoon I hung the shroud and set up the projector. Sunday morning I was playing Banff Springs. Maybe 12 hours total, and half of that was me figuring out where to put the projector.”
Twelve hours. Spread across a weekend. You start Saturday morning, you play 18 Sunday afternoon.
Here’s the breakdown:
Saturday (6–8 hours):
- Mount ceiling brackets for the frame (1 hr)
- Cut and connect EMT conduit (2 hrs — measure twice, cut once)
- Tension the impact screen on the frame (1.5 hrs)
- Hang the side shroud and top apron (1–1.5 hrs)
- Mount the projector (1 hr, longer if you’re figuring out throw distance)
Sunday (4–6 hours):
- Run cables and set up the computer/iPad (1 hr)
- Configure projector alignment (1–2 hrs — this is the fiddly part)
- Install GSPro or your sim software (30 min)
- Calibrate launch monitor height and alignment (30 min)
- First ball (1 min)
- Fix the projector alignment because it was slightly off (also 1 min, but it’ll happen)
The one thing that eats time: projector positioning. Getting the image perfectly framed on the screen — no keystone, no tilt, no shadow from the overhead mount — takes longer than you expect. Plan for that. Don’t rush it.
A guy on Golf Simulator Forum summed up the typical experience:
“My ‘one weekend build’ turned into a two-weekender because I had to wait for a different HDMI cable. But the actual work was done in about 10 hours over two Saturdays.”
The work is fast. The waiting — for parts, for the right tool, for a second pair of hands — is the variable.
2–4 Weeks — The Full Room Build (With Construction)
This is the deep end. You’re not just mounting a screen in a garage. You’re building a room.
Maybe you’re finishing a basement. Maybe you’re building a dedicated golf space where there wasn’t one — framing walls, running electrical, adding HVAC, installing proper flooring, soundproofing, paint, lighting. All of it.
This isn’t a weekend project. This is a construction project.
Real timeline from a guy who did it:
“Week 1: Demo and framing. Week 2: Electrical, insulation, drywall. Week 3: Mud, tape, sand, paint. Week 4: Flooring, baseboards, and finally the sim setup. Probably 150 hours of work over the month. Worth every one.”
Four weeks. One hundred fifty hours. But here’s what he ended up with: a climate-controlled golf room with soundproofing, dimmable lights, and a finish that looks like it belongs in a custom home — not a garage.
The actual timeline for a full build:
| Week | Work |
|---|---|
| Week 1 | Permits (if needed), demo, framing, rough-in electrical |
| Week 2 | Drywall, mud, tape (drying time kills speed here) |
| Week 3 | Sand, prime, paint, flooring, trim |
| Week 4 | Lighting, projector mount, enclosure build, calibration, finishing touches |
The killer is drying time. Mud takes a day to cure. Paint takes overnight. Flooring adhesive takes a day. You can’t compress drying. This is where the “one weekend” guys realize they’re in for a longer ride.
But here’s something interesting: the guys who do the full build almost never regret taking the time.
“Took me a month. If I’d rushed it, I’d have regretted it every time I walked in. Now I walk in and it feels like a room, not a garage with a screen.”
The Three Questions That Determine Your Timeline
Not sure which bucket you’re in? Answer these three things honestly:
1. Are you building in an existing space or creating one?
Existing garage that just needs a screen and projector? You’re in the “one weekend” camp.
Empty room in the basement you need to finish first? You’re in the “2–4 weeks” camp.
Hitting into a net on the driveway? That’s “30 minutes” and you can do it tonight.
2. Are you okay with “good enough” or do you need “finished”?
Some guys hang a screen from two Harbor Freight conduit pipes and call it a day. Looks rough. Works fine. That’s a Saturday.
Other guys run baseboard, paint the ceiling flat black, and epoxy the floor. That’s a month, minimum, and costs more.
Both are right. The question is which one you are.
3. Are you building alone or with help?
One guy with a drill and a level can build a Carl’s Place enclosure in a weekend. It’s harder alone, but doable. You’ll be sore Sunday night.
Two guys? That same build takes one afternoon. Someone to hold the far end of the conduit, someone to spot the projector height, someone to tension the screen while you clip. Four hours, done.
A full room build with construction? You want help. Doing drywall solo is a special kind of punishment.
The One Thing That Wrecks Every Timeline
Every thread on this topic has the same confession:
“My build took twice as long because I didn’t know what I needed until I needed it.”
Extra conduit fittings. Longer HDMI cable. A different mount for the projector. A stud finder. A level that actually works.
The guys who finish fast are the guys who over-order. They buy extra cable, extra fittings, extra everything. They get a roll of velcro, a pack of zip ties, a tube of black caulk for light leaks. They don’t stop to run to Lowe’s mid-build.
The guys who take twice as long? They ran to Lowe’s three times. On a Saturday. In July.
The pro move: Order everything you think you need, then add 20% more. Cable ties, HDMI cables, wall plates, blackout fabric, extra grommets. The $50 of “extra shit I probably don’t need” saves you three trips to the hardware store and the six hours those trips cost you.
The Real Answer
Here it is, plain:
| Setup | Time | When you’re hitting balls |
|---|---|---|
| Net + mat + launch monitor | 30 minutes | This afternoon |
| Full enclosure + projector | One weekend | Sunday afternoon |
| Full room build + sim | 2–4 weeks | Next month |
| Full room build + sim + two guys | 2 weeks | Two Sundays from now |
The most common path? Start with the net. Realize you’re using it four times a week. Upgrade to the full enclosure over a weekend. Spend the next year slowly improving the room around it.
That’s the journey. And it’s not a long one.
The first step — “box to first ball” — takes 30 minutes. That’s less time than a trip to the driving range. You could order everything right now, have it by the weekend, and be hitting balls before anyone else in the house wakes up.
Every guy who’s done it says the same thing:
“I spent six months thinking about it and one weekend building it. Should have done it last year.”
