4. Tower Bridge 10214

Building the miniature set of the world-famous structure requires you to add the suspensions by attaching miniscule pieces together and the spires on the top of each bastion needs skill to be attached properly so that the height of both bastions remain the same. Since 1894, this timeless classic landmark of London on the River Thames has been charming both to local people and tourists –you need advanced building techniques to recreate that magic.

Highlights: The most complicated part of the set is the functional drawbridge that can be opened like the original Tower Bridge to let cargo ships pass.

• The bridge with four miniature vehicles namely the red London double-decker bus, the green car, yellow truck and black taxi will take you back to the London streets, but require skills to make sure that the bridge remains steady.
