Build a bird box!

This is a part of an old article I wrote some years back but on the request of a twitter friend Heather Wilde of @KidsNorthWest I’m uploading it here as she’s holding a bird box building party soon so hopefully she’ll find this timely and useful 🙂

Birds are an integral part of any garden, be it an urban one or one out in the sticks. More and more people are feeding birds (click for a novel bird feeder idea) and enjoying this doorstep wildlife spectacle, and what better way to further enhance it than to provide some simple accommodation for them to raise young in.


I’ve been a keen bird watcher since I was a child when my mother gave me a collection of children’s “Things to Do” cards she had received by collecting Batchelor’s soups labels. Within the pack was a card about bird watching and how to start a field note book, and I thought I would give it a go. We only had a small back garden on an estate in a village near Leeds, but having spent many an hour at the kitchen window I’d recorded in excess of 30 species of birds there in my first year of ‘watching’. I was hooked and still am to this day, be it rarity turning up locally, the first swallow of the year or a house sparrow feeding her brood on the window ledge.


Over the years I’ve lived in both urban and rural settings, and for some reason that escapes me I’ve developed a habit of making and putting up a bird box at the beginning of each year. Winter is a good time of year too, it gives the box a chance to weather and settle before the breeding season starts in earnest. It’s an extremely simple and cheap thing to do. It requires minimal woodworking skills and is perfect for getting the kids involved in something that might just have the same impact as the cards my mum gave me all those years back.

On top of that it’s a great idea for new and unestablished gardens that may not have the natural nest sites for birds. Of course you could just buy one ready made however different birds have different housing requirements just like people.


This design alone can be modified to attract around 7 different species of bird by simply changing the size of the entrance hole – 25mm for coal, blue and marsh tit, 28mm for great tits and tree sparrows, or 32mm for house sparrow and nuthatches.


Many garden bird species are declining in numbers year on year, yet they are an essential element for the success of our garden ecosystem, so why not spend a couple of pounds and a winter hour knocking up some accommodation for them, you’ll be repaid by the bucket load when you see the first young appearing at the entrance hole.


And just to prove I’ts not beyond anyone’s reach to build, my youngest son (with some assistance from his older brother) performed almost the entire build himself. I built one myself at the same time and I have to declare, his was better!



What you will need


  • Saw
  • Hammer
  • Measuring tape
  • Galvanised nails (3cm)
  • Drill
  • Hole saw or large drill bit
  • Bored teenager or enthusiastic youngster ‘optional’


  • 15cm x 2cm x 142cm tanalised plank
  • 15cm x 5cm rubber strip (car inner tube, pond liner etc)
  • Small hook and eye fitting



Step 1

Using the template below, measure out the cuts to be made on the plank. Most hand saws have 90 and 45 degree guides built into the handle these days, or alternative use a set square. Then cut the sections out.



Step 2

Having decided on the entrance hole size, drill the entrance hole. It needs to be at least 125mm from the base. This means the nest will be low enough within the box to minimise the possibility of predation by cats.


Step 3

Attach the side panels to the back piece using the hammer and nails. Be sure to check the sides are positioned directly opposite each other or the rest of the build will be out of line!


Step 4

Side the base into position between the two side pieces and nail it to the sides. Drill a few small drain holes in the base. This is precautionary measure as the completed box should remain dry inside.


Step 5

Making sure that you have the entrance hole nearest the top, place the front section on and nail it to the sides and base.



Step 6

Nail the rubber strip to the roof section first,  and then nail the flap to the back section. Hinging the lid in this way means you can easily access the box to clean it out at the end of the season should it be required.



Step 7

As a further precaution against predation, add the hook and eye to the lid. It will also stop any gusts of wind flipping the lid up.


Step 8

Decide on the location for your new nest box choosing a sheltered spot 2 metres or more above the ground. Face it between northeast and southeast so it avoids the worst of the weather and is not exposed to too much sun.
