Can I rebuild old LEGO® sets from loose bricks?

The short answer

Yes. Scan your loose bricks with BrickVision™ and Brick Finder ranks the official LEGO® sets they match. Pick the set you remember, or the one you are closest to finishing, and you see exactly which pieces are missing. For 1,800+ sets you can watch the build in 3D and make step-by-step instructions to save as a PDF or print.

From a box of old bricks to a finished set

  1. Scan the old bricks tray by tray and save them in one collection.
  2. Open What can I build? and look at the top matches. They often point straight to the sets your bricks came from.
  3. Pick a set and check the missing pieces, pictured and counted.
  4. Order missing pieces online from LEGO® Pick a Brick or BrickLink, or swap in a similar piece you have.
  5. Follow the build: watch it assemble in 3D, or tap Instructions for a step-by-step manual.

Signature pieces help

Printed pieces, unusual shapes and rare colors often belong to only a few sets. If you remember a special piece, start with it: it narrows the list fast.

Which set should I rebuild first?

Start with a set near the top of the list, where you already have most of the pieces. You will finish sooner and need to buy less.
