Build a Bird House from Household waste

A Simple, Eco-Friendly Guide for Your Garden


Creating a bird house from scrap materials is a brilliant way to support local wildlife while cutting down on waste. Many items you might normally throw away can be turned into safe, functional homes for your garden birds. With a little creativity, you can make something sturdy, weatherproof and inviting for nesting birds.

Why Use Household Waste?

Using reclaimed materials has several benefits:

  • Reduces waste by giving discarded items a second life
  • Costs almost nothing to build
  • Encourages creativity and family involvement
  • Supports local wildlife, especially cavity-nesting birds
  • Keeps resources out of landfill while helping nature thrive

From old wooden boxes to broken drawers, many items can form the structure of a bird house with very little modification.

Materials You Can Repurpose

Here are some common household items that make excellent birdhouse components:

Wooden Tea / Biscuit / Wine Boxes

Sturdy, natural and perfectly sized for small bird houses.

Scraps & Offcuts of Wood

Leftover bits from DIY projects make great walls, bases and roofs.

Small Wooden Crates

Fruit crates or gift boxes can be converted into nesting boxes with minimal effort.

Broken Terracotta Plant Pots

Weather-resistant and breathable; ideal for a rustic-style bird shelter.

Old Cutting Boards

Cracked or worn boards can be turned into strong panels.

Gourds or Pumpkin Shells

Hollow gourds make traditional, natural nesting houses.

Materials to Avoid

Metal tins, glass jars, or thin plastics — these can overheat, trap condensation or become unsafe for birds.
(They’re great for insect hotels, but not for nesting birds.)

What Else You’ll Need

  • Galvanised screws or nails
  • Drill & entrance-hole bit (25–32 mm for common garden birds)
  • Sandpaper
  • Waterproof roof covering (scrap felt, slate or wood)
  • Optional: Non-toxic outdoor paint or stain
  • Optional: Straw or dried grass for a small starter layer

Step 1

Prepare the Main Body

  • Choose your base item — a wooden box, crate, or assembled scrap pieces.
  • Sand rough edges to protect feathers and tiny feet.

Step 2

Add an Entrance Hole

Drill a circular entrance:

  • 25 mm → blue tits, coal tits
  • 28 mm → great tits
  • 32 mm → sparrows

If using a gourd or plant pot, cut the entrance with a small saw.

Step 3

Install the Base and Walls

  • If using loose scrap wood, screw the pieces together to form a simple box.
  • Ensure the base has small drainage holes.

Step 4

Weatherproof the Outside

  • Paint or stain the exterior only, using natural colours.
  • Avoid painting the inside.

Step 5

Add a Small Nesting Layer

  • Place a small handful of straw or dried grass to encourage nesting.
  • Avoid fluffy materials that can tangle around chicks.

Step 6

Position Your Bird House

Placement is key for success:

  • Mount 2–4 metres above ground
  • Choose shade or partial shade
  • Face away from prevailing winds
  • Keep the flight path clear
  • Fix securely so it doesn’t sway

Tips for Success

  1. Install the house in autumn or winter so birds can find it early.
  2. Clean the bird house once a year (after nesting season).
  3. Avoid adding perches: predators use them as stepping points.
  4. Keep the entrance hole smooth and round — no sharp edges.
  5. Patience is key — some birds take weeks or months to move in.

A Fun, Sustainable Garden Project
Building a bird house from reclaimed materials is a rewarding way to welcome wildlife into
your garden while doing your part for the environment. Every homemade shelter helps local
birds find a safe nesting site — especially during harsher seasons or when natural tree
cavities are scarce.
