Build your pet
out of bricks

A 3D scan of your pet, a brick version you can try in multiple sizes (how many depends on your pet’s shape), then a parts list and a step-by-step guidebook for the size you choose. Every size shows its exact height, width, length, brick count and cost.

By number of bricks, from Mini (about 200 bricks) upwards. How many sizes your pet gets depends entirely on its shape. We pick each size’s height to suit your pet, so a greyhound stands taller than a hamster with the same number of bricks. Pets with very thin legs, like greyhounds, only get the sizes we’re confident are structurally sound, and if two sizes would come out almost the same height we keep the bigger one. You see the exact height, width, length, brick count and cost of every size before you choose.

No. We design your pet; you buy the genuine LEGO® bricks yourself from LEGO® Pick a Brick by uploading the parts list we give you. LEGO® Pick a Brick takes payment, sets the shipping cost and delivers.

It depends on the size. For our example pets it’s about £20–£30 for Mini (about 200 bricks), £100–£145 for Medium (about 800) and £345–£460 for Extra large (about 2,500), plus delivery. You see the exact cost for your pet, in your country, before you choose a size.

About 15 minutes for most pets, from your photos to your parts list and guidebook: a few minutes for your 3D model, a few more for its brick sizes once you approve it, and a minute or two for your guidebook. The bricks then come from LEGO® Pick a Brick, usually in one to two weeks and sometimes up to four, depending on where you live.

LEGO® Pick a Brick delivery can take a few weeks at busy times, so start early and order your bricks as soon as your guidebook is ready.

AI turns your photos into a 3D model for you to check before it becomes bricks. Small sizes are chunkier; bigger sizes show more detail.

We don’t offer change-of-mind refunds once the digital service begins with your consent. If a 3D scan fails on our side, its credit is returned. Your statutory rights still apply.

Aim for four clear, well-lit photos: face, whole body from the side, behind, and front, in any order. Three can work if they show the face, side and back very clearly. Dogs and cats must be standing. We’ll check the views together and help with anything missing.

The guidebook shows every step, a few bricks at a time, with clear pictures. Mini is about 200 bricks: a cosy evening or two. Extra large is about 2,500 bricks: a proper project. Have a look inside the sample guidebook first.

Preview your pet’s sizes for as long as you like. The size you choose is the one for your parts list and guidebook. Want another size later? Choose New size under your pet in My pets. It’s a new £29 order, and we reuse your photos.

We only use bricks LEGO® Pick a Brick sells in your country, and we check their stock before you order. If any are out of stock, we show you which. Then you choose: swap them for a close colour, or wait until they’re back.

No. BuildMyPet is an independent company. The LEGO Group does not sponsor, authorise or endorse us.

The finished pet is a display model, not a toy. LEGO® bricks are small parts, so keep them away from children under 3, and younger builders will want a grown-up to help.

Yes! Aim for four clear photos of the pet; three can work if the views are very clear. Have the bricks sent from LEGO® Pick a Brick to any address, then print or share the guidebook.

29 countries: the UK, the US, Canada, Australia, New Zealand and 24 in Europe. We work out your parts and prices for your country’s LEGO® Pick a Brick store, so you choose your country before your 3D scan.

We use them to check your photos and make your pet’s 3D model, with the help of trusted AI services, and keep them with your account. Our privacy policy has the details.
