Golf, year‑round, in a room built for it.
Custom Sims LLC designs and builds fully custom indoor golf simulators for homes, clubs, and facilities across Michigan. Custom-built enclosures. Tour-quality turf. Pro-grade impact screens. Built to perform.
Where are we building?
Three kinds of rooms, three kinds of buyers. The build is custom either way.
Residential
Basements, garages, pole barns, and dedicated golf rooms. Your space, designed around your swing.

Commercial
Golf clubs, indoor facilities, and venues. Multi-bay builds that hold up to daily traffic.

Institutional
Schools, teams, and training programs. Practice space that works in February.
See institutional →No such thing as guesswork.
Every build starts with the room you actually have. We measure it, plan it, and tell you honestly what is possible before anyone buys anything.

Details matter.
We paint every enclosure matte black for a reason. Any light that bleeds through the impact screen gets absorbed, not bounced around the room. More contrast. Cleaner image. Premium finish.
That is one decision out of a few hundred we make on every build. You will never see most of them. You will see the result.
Flushing Schools, Flushing, Michigan

“Amazing sim room! You do incredible work. I use the sim room you created for me on a daily basis and people always comment how sweet it is.”
Built by a golfer.
A lifelong competitive golfer who coaches junior players and runs a simulator league out of his own house in the winter.
Most people who install simulators learned golf second. Randy learned construction second. That is the whole difference, and you can see it in every room he builds.
