How to build an indoor putting green

By Bunnings magazine / Aug 2025

It’s time to bring the golf Masters to your home with this indoor putting green.

Overview

At just 1m wide, this indoor putting green will fit in most hallways or you can set up wherever you have space, including undercover outside. When you’re done, fold it up and stash in the wardrobe or slide it under the bed!

Why you need a D.I.Y. indoor putting green

  • Practise your putting at home at any time. 
  • Can be used indoors or outdoors undercover.
  • It folds away neatly to be stored.
  • Made from a 3m length of short-pile synthetic turf and layers of self-adhesive foam for the mound under the cups.
  • With a stopper at the end of the run it will keep your balls on the green and save work for the caddy!

Steps

  1. 1

    Start by marking the holes

    On the back of the turf, use a white marker and follow the diagram (above) to mark the hole centres. Centre 90mm pipe over the marks to transfer circles. Use a utility knife to make starter holes; finish cutting with scissors.

    Time to cut the foam

    To make a stopper, cut a pool noodle to 1m long, mark across the end with pen as a guide then cut in half lengthwise. Next, cut foam roll into two 900mm lengths with scissors. Cut one piece to 600mm wide (Layer 2). The other is Layer 1.

    Tip: Check the width of the mat fits your space, trimming as needed.

    Use your pool noodle to make a stopper

    On one end of Layer 1, peel back enough paper to centre the stopper flat against the edge and press into the adhesive. Turn over to apply double-sided turf tape along the other side. Position turf beside foam so short edges meet. Remove the double-sided tape liner and press turf edge onto tape.

    Finish off your putting green stopper

    Centre and press the top of the turf along the tape. Remove the paper from Layer 2 and press, adhesive side down, over Layer 1 and the turf edge. Turn over to remove Layer 1 paper. Fold the turf back over the stopper, pressing into the join and over Layer 1.

    Cover up the cup holes

    Cut out foam holes from the front. On the back, cut a microfibre cloth into quarters, centre over holes and adhere with turf tape. Position tape on the turf, against all edges of the foam, including under the stopper.

    Attach the shelf mat

    Cut 1010mm length of shelf mat. Remove tape liner, centre the mat over the foam and press to adhere. Tuck ends under the stopper, adhere with tape and trim mat. Adhere the remaining mat along the turf. Mark rounded corners at the base and cut.

    Keep in mind...

    Keep scissors and utility knives out of reach of children.

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions.
