Hedgehogs are among the most welcome visitors to any British garden, but their numbers have fallen sharply in recent decades. A simple, well-placed hedgehog house can give these nocturnal wanderers a safe place to rest, hibernate, and raise their young. The good news is that you don’t need to be a carpenter or spend a fortune. With a few untreated boards, some dry leaves, and a quiet corner, you can create a genuine lifeline for local wildlife.

Why a hedgehog house makes a difference

Hedgehogs roam surprisingly far in a single night, often covering a kilometre or more. That journey is fraught with danger: busy roads, tidy fences, and manicured lawns offer little shelter. A purpose-built house provides a dry, predator-resistant chamber where a hedgehog can sleep through the day or hibernate through the coldest months. It also gives you a front-row seat to their quiet habits, without needing to disturb them.

Unlike a compost heap or a pile of logs, a proper house has a narrow entrance tunnel that keeps out badgers, foxes, and domestic cats. It stays dry inside, which is critical because damp hedgehogs can quickly become ill. And because it mimics the natural hollows they would seek out in hedgerows, it encourages them to stay in your garden rather than move on.

Picking the perfect quiet corner

Location is everything. Choose a quiet corner of the garden, away from footpaths, patios, and anywhere your dog or cat likes to patrol. The house should sit on firm, level ground, ideally raised slightly on bricks or a paving slab to stop damp rising from the soil. Avoid low spots where water collects after rain.

Face the entrance away from the prevailing wind—in the UK, that usually means avoiding a south-westerly aspect. A north- or east-facing entrance is often better. You also want dappled shade rather than blazing sun all day, and some nearby cover such as a hedge, a shrub, or a stack of logs. Hedgehogs like to approach under cover, so a house placed in the open will rarely be used.

Building a simple dry chamber

You only need a few basic materials: untreated wood (pine or exterior-grade plywood is ideal), galvanised screws, and a waterproof cover for the roof. Avoid treated timber, which can contain chemicals harmful to hedgehogs, and never use creosote or wood stain inside.

• Base: about 40 cm by 40 cm.
• Height: roughly 30 cm, giving a cosy but airy chamber.
• Entrance tunnel: 15 cm long and 12 cm by 12 cm square. This deters larger predators while letting hedgehogs pass easily.
• Roof: hinged for cleaning, but secured with a latch so it cannot be blown open. Cover it with roofing felt or a piece of pond liner.

Assemble the box with screws rather than nails, which can work loose. A solid floor is fine as long as the whole house is raised on bricks. Line the inside with a layer of dry leaves, but leave the chamber mostly empty so the hedgehog can arrange its own nest. Check for sharp edges or protruding screw tips—run your hand over every surface before placing it.

Camouflaging with leaves and natural cover

Once your house is in position, cover it with a generous heap of dry leaves. Oak, beech, and hawthorn leaves are perfect because they are broad and slow to rot. Pile them over the roof and around the sides, leaving the entrance tunnel clear. This does two things: it insulates the chamber, and it makes the house look like a natural part of the garden rather than a man-made box.

Add a few handfuls of leaves inside as well, but don’t pack them tightly. Hedgehogs will rearrange them into a snug nest. You can also place a piece of turf or a light layer of soil on top of the roof, but avoid anything heavy that might collapse. Finally, scatter a few dry leaves along the approach path to the entrance, so the hedgehog feels sheltered as it comes and goes.

Respecting hibernation and beyond

From November to March, hedgehogs may be hibernating inside your house. During this time, do not disturb the residents. Don’t lift the roof, don’t poke around the entrance, and don’t move the house. Even a brief disturbance can wake a hibernating hedgehog and burn precious energy it needs to survive the winter.

If you need to clean or check the house, wait until April or September, when hedgehogs are active but not breeding heavily. A quick peek in late spring can tell you whether the house has been used, and you can replace damp leaves with fresh dry ones. If you find a hedgehog out during the day in winter, it may be unwell—contact a local wildlife rescue for advice rather than handling it yourself.

Beyond the house itself, a few small touches make your garden more hedgehog-friendly. Leave a shallow dish of fresh water, never milk or bread. If you put out food, use meat-based cat or dog food. Create a 13 cm gap in your fence to link your garden to next door. And always check long grass before strimming. With a little patience, your simple wooden box will become a quiet, vital refuge for one of Britain’s best-loved animals.
