A hedgehog house is not just a box with a hole in the front. If it is too exposed, too wet, too easy for predators to reach, or too often disturbed, hedgehogs are unlikely to treat it as a safe shelter.

This guide builds a simple plywood hedgehog house with a main nesting chamber, entrance tunnel and removable roof. It is a general beginner wildlife shelter project, not a feeding station and not a specialist rescue enclosure.

• Untreated plywood
• Entrance tunnel included
• Removable roof
• Solid-floor or open-base option
• Quiet garden placement
• Low-disturbance design

What makes a good hedgehog house?

A useful hedgehog house should give shelter from weather, reduce disturbance and make it harder for larger animals to reach inside. The tunnel or internal baffle is not just decorative. It helps stop predators from being able to reach straight into the nesting chamber.

The house should be placed somewhere quiet, shady and sheltered. The Wildlife Trusts recommend a shady, quiet spot and specifically warn not to skip the tunnel because it helps prevent predators from reaching inside. The Natural History Museum also recommends a flat, quiet and shady spot, ideally near a garden boundary such as the foot of a wall or fence.

Use plywood as the main material route

For this project, suitable plywood is the main material route. A plywood box is easier to plan from panels than trying to build the whole shelter from narrow boards.

Choose an untreated plywood suitable for the project. Avoid treated, coated or film-faced boards for this wildlife shelter. If using an alternative such as untreated PSE timber, check that it is suitable, thick enough and practical to build into a weather-resistant box.

Solid floor or open base?

There are two sensible approaches. This guide gives a solid-floor cut list because it is easier for a beginner to build and move as one box. However, an open-base design can also be suitable where the house sits on dry, well-drained ground and is packed naturally with leaves.

If you are unsure, build the solid-floor version below, add a few small drainage holes, and place it somewhere sheltered and dry. If your garden has a naturally dry, hidden spot under shrubs or near a boundary, an open-base version can also work well.

Cut list for a plywood hedgehog house

This cut list creates a simple rectangular hedgehog house with a main chamber, entrance opening and internal tunnel/baffle. Use it as a practical beginner build. If your plywood thickness changes, dry-fit the pieces before final fixing.

Materials and tools

Materials

• Suitable untreated plywood
• Exterior-suitable screws from timber fixings
• Optional suitable nails from nails
• Optional untreated PSE timber for battens, stops or small fixing blocks if needed
• Dry leaves or straw for bedding material
• Optional waterproof cover layer outside the box, fitted so the roof remains accessible

Tools

• Tape measure
• Pencil
• Square
• Saw or circular saw
• Drill/driver
• Drill bit for pilot holes
• Jigsaw or handsaw for entrance opening
• Sandpaper for sharp edges
• Eye protection and suitable dust protection

Step-by-step build method

Step 1: Mark and cut the panels

Mark every panel before cutting: back, front, two sides, floor, roof and baffle. Label each piece in pencil so you do not mix them up during assembly.

Cut slowly and keep the edges as neat as possible. Lightly sand sharp edges, especially around the entrance opening.

Step 2: Cut the entrance opening

Cut an entrance opening in the front panel, close to one side rather than centred. Around 120mm square is a practical size. Keeping it to one side helps the tunnel or baffle create a protected route into the main chamber.

Remove sharp splinters around the entrance. The opening should be smooth enough that it does not catch or scrape.

Step 3: Assemble the main chamber

Fix the side panels to the back panel, then fit the front panel. Pre-drill pilot holes to reduce splitting and keep the panels aligned as you work.

If building the solid-floor version, fit the floor panel now. Drill a few small drainage holes so moisture cannot sit inside the box.

Step 4: Fit the tunnel or baffle

Fit the internal baffle so a hedgehog has to turn before entering the nesting chamber. This protects the chamber from direct wind, rain and predators reaching straight through the entrance.

If you are building the optional external tunnel, assemble the tunnel pieces and fix them to the entrance. Do not skip this protection stage. It is one of the most important parts of the design.

Step 5: Fit the roof as a removable lid

The roof should overhang the sides and front to help shed rain. It should also be removable so the house can be checked or cleaned when it is definitely empty.

Use simple stops, battens or a safe fixing method to keep the roof in place without permanently sealing it shut. The roof should not blow off in wind, but you should still be able to remove it when needed.

Step 6: Keep the inside untreated

Do not paint, stain, oil or preserve the inside. Leave the internal chamber bare and clean. Add dry leaves or straw as bedding material, and leave extra dry leaves nearby so hedgehogs can arrange the nest themselves.

If adding any weather protection outside the box, keep it external and make sure the removable roof can still be accessed.

Where to place the hedgehog house

Choose a quiet, shaded and sheltered part of the garden. A spot near a boundary, under shrubs, by a hedge or close to a fence line often makes more sense than an open lawn.

• Place it somewhere quiet and low-disturbance.
• Face the entrance away from the worst wind and rain.
• Hide it under shrubs, hedge cover, logs or leaves.
• Keep the entrance clear enough for hedgehogs to get in and out.
• Avoid putting it where water pools.
• Do not turn the shelter into a feeding station.

When and how to check or clean it

Hedgehog houses should be disturbed as little as possible. Only check or clean the house when you are confident it is not being used. If you lift the roof and find a hedgehog inside, replace the roof carefully and leave it alone.

Wildlife guidance varies slightly on the best cleaning window. The safest beginner advice is to avoid hibernation and nesting periods, check only when the house is empty, and keep disturbance to an absolute minimum.

Common mistakes that make hedgehog houses less useful

• Skipping the tunnel or baffle: the chamber becomes easier for predators or pets to reach.
• Using treated or coated material: use suitable untreated plywood or untreated timber only.
• Fixing the roof permanently: the house needs access for checking or cleaning when empty.
• Placing it in the open: hedgehogs prefer hidden, quiet and sheltered spaces.
• Putting it where water pools: a damp house is unlikely to be useful.
• Disturbing it when occupied: if a hedgehog is inside, replace the roof and leave it alone.
• Turning it into a feeding station: keep food away from the sleeping shelter.

FAQs

Final thought: make it hidden, dry and undisturbed

A hedgehog house does not need to look perfect. It needs to feel safe. That means untreated material, a protected entrance, a dry chamber, a removable roof, and a quiet position where the animal is unlikely to be disturbed.

Build the shelter carefully, hide it well, and then resist the temptation to keep checking it. The less it is disturbed, the more useful it is likely to be.
