1. Introduction

Imagine transforming your backyard into a whimsical, challenging Mini golf course that family and friends can enjoy year-round. Whether you’re building a single hole or a full 9-hole course, this guide walks you through every step.

2. Planning Your Course

Evaluate Your Space

  • Measure the available area.
  • Consider terrain – flat areas are easier, but slopes can add fun challenges.
  • Note any existing features (trees, fences, patios).

Design Your Layout

  • Sketch a basic layout with 3 to 9 holes.
  • Use curves, corners, elevation, and obstacles to create variety.
  • Ensure there’s enough room for people to stand and play comfortably.

Choose a Theme (Optional)

Themes can boost creativity: pirate, jungle, retro arcade, outer space, etc.

3. Tools and Materials

Basic Tools

  • Saw (for wood or PVC)
  • Drill and screws
  • Hammer
  • Shovel (for ground prep)
  • Level
  • Measuring tape

Materials

  • Plywood or decking boards (for framing)
  • Outdoor carpet or artificial turf
  • PVC pipe or metal cups (for holes)
  • Concrete blocks or bricks (for edges)
  • Paint and sealant (for design and weatherproofing)
  • Adhesive or nails/staples (for turf)

4. Building the Base

Option 1: Ground-Based Course

  1. Clear and level the ground.
  2. Use bricks, edging, or landscape timber to frame holes.
  3. Add compacted sand or gravel as a base for drainage.
  4. Lay turf over the top, secure it, and cut hole openings.

Option 2: Platform-Based Course

  1. Construct a wooden platform using pressure-treated plywood and 2x4s.
  2. Elevate slightly for drainage.
  3. Frame edges with boards.
  4. Secure turf and cut out holes.

5. Creating Obstacles and Features

Make it interesting with DIY or repurposed materials:

  • Ramps – Wooden boards angled upward.
  • Bridges/Tunnels – PVC pipes or small wooden arches.
  • Spinners/Gates – Rotating paddles or swinging doors.
  • Water Features – Small fountains or channels (optional but advanced).
  • Moving parts – Use battery-powered toys or motors for rotating challenges.

6. Surfacing Your Holes

  • Use outdoor artificial turf with a short pile for best ball movement.
  • Apply adhesive, staples, or nails to keep turf flat and secure.
  • For natural turf, mow closely and keep it dry for best play.

7. Adding the Fun: Themes and Decorations

Incorporate your theme into:

  • Signage – Label each hole with names (e.g., “Dragon’s Curve” or “Plumber’s Plunge”).
  • Decor – Use thrifted items or garden ornaments.
  • Lighting – Add solar lights for night play.
  • Sound – Small speakers with background music or themed effects.

8. Maintenance Tips

  • Regularly clean turf and fix loose edges.
  • Replace worn-out parts like ramps or signage.
  • Check levelness and ball roll quality.
  • Protect wooden elements with weatherproof paint or sealant.
