Building an indoor miniature golf course is a great way for a golf family to enjoy the game while not having to leave the house. A mini golf course can make use of basement or attic space, while also being easy to store along a side wall by stacking the holes atop each other. Creating an indoor miniature golf course is mostly planning and imagination.
Difficulty: Moderately Easy
Create a basic drawing of the space you plan to use, such as your basement or attic. Use notebook or graph paper. The drawing doesn't need to be exact in size, but it should represent the shape of your room. Once you have this on paper you can begin the measurements.
Use a tape measure to calculate the total available floor space. Measure the width by the length. Write this down on the drawing. Now block out each item which takes up floor space (such as a washer and dryer, water heater, or furnace) on the drawing by measuring from the wall to the item. If you have a row of obstacles, measure from the wall to the closest obstacle and create a block around everything in the row. This will give you the available working space when you build your indoor miniature golf course.
Plan the course to fit the available space. When you design the layout, remember to end each hole at the beginning of the next so that players can simply step forward to the next green. Efficient use of space can be achieved with a serpentine pattern by placing the end of one hole next to the tee of the next hole. The final hole can be placed lengthwise across the top of the serpentine pattern, ending the final hole at the starting point.
Build the holes to use minimum space for the fairways by making each fairway 24 inches wide. Build your framework out of 2 x 4s to make the frame both easy to move and high enough to keep the golf ball on the course. You can build angles and corners into the course by planning holes to fit like puzzle pieces; this will make the course more challenging and enjoyable. Design the holes so that a hole in one is not impossible. Build holes where you can bank the ball off of a hazard into the cup.
Use old sections of carpeting or synthetic turf for the greens. You can use any type of carpeting except shag because the fibers are too long. Concrete flooring is too smooth to control the ball. Cut the carpet sections so that the carpeting meets the outside edge of the frame. Turn the carpeting face down, then lay it over the frame. Nail the carpeting to the underside of the frame.
Turn the frame over so that the carpet becomes the base, or green, of the hole. You can now place your obstacles along the green, if you haven't built them into the frame. Build your obstacles out of wood blocks, coffee cans with the ends cut out, or plastic containers with weights in them as bumpers. The wood blocks can be nailed together as a "T" and placed at various angles to form corners or ramps (placed on its side). The cans can be made into tubes. Each obstacle can be moved or arranged to create a different course each time.
