Building Guide: Things to Do Before You Start

Now that you’re going to build a mini-golf course of our own, you’ll have to make sure of certain important things before the start of your DIY project. 

Area

Whether you intend to build an indoor or outdoor setup, make sure that you have enough space for the construction. 

Typically, a 9-hole mini-golf course can be built in a 140′ x 140′ area, which is approximately 0.5 acres. Make sure to clear at least that much space for flawless construction.

Shopping List 

To build your mini-golf setup, you’re going to need supplies! 

There’s a whole list of materials that are used in the construction of a mini-golf course. Make sure that you have all of them before you start. Here’s the list:

✅ 2×4-foot sheet of 3/4-inch medium-density fiberboard (for 1 panel) 
✅ Five deck balusters (for 1 panel)
Wood glue
1/2 yards of 72-inch-wide green felt (for 1 panel)
Spray adhesive
✅ 3-inch PVC pipe fitting (coupling, cap, or adapter)
✅ 5 composite wood balusters (for 1 panel)
✅ Outdoor welcome mat or artificial turf

In addition to these materials, you’ll require the following tools: 

Miter box with a backsaw
Drill/driver fitted with 4-inch hole saws
Spring clamps
Plastic drop cloth
Utility knife
Framing square
Hacksaw

Cost

Before you start, make sure that you have enough money for the project.

The best way to ensure that is by making a cost estimate. Roughly, buying a 9-hole miniature golf course setup can cost you around $7,000, but making one on your own can be cheaper.

Step 7: Setting Up the Golf Course

Once you’re done making the required amount of panels you want, it’s time to set up the golf course.

  • Clear out the surface.
  • Position the panels according to the layout plan.

Step 8: Adding the Hurdles

You can add different obstacles according to your choice for different levels of competition. 

Build a ramp or a loop-de-loop as shown in the video or simply put the obstacles on the panel to use them as hurdles.
