Big Builds: 5,000+ Pieces

Projects measured in weekends, not evenings. The 9,090-piece Titanic, the 10,001-piece Eiffel Tower, a 9,023-piece multi-level space station, an 8,445-piece deep-space freighter, a 6,785-piece heavy walker, a 5,201-piece superhero tower and a 5,129-piece collectors’ express train — all between £110 and £185, which is where the saving against official-brand pricing is largest.

Read the “Please read before ordering” section on each page: these sets usually ship with unsorted bags and plain outer boxes, and they need real display space.

Every order: UK stock, same-day dispatch on orders before 2pm (Mon–Sat), free tracked UK delivery, 28-day returns and UK-based support. Missing a piece? We send a replacement.

Frequently asked questions

How long does a 9,000-piece set take to build?

Most builders report 40–60 hours including sorting — three to six weekends at a relaxed pace.

Are the bags numbered?

Usually not. Bags are grouped by part type. Our Build Log guide explains the sorting method we use; budget an evening for it.

How much space do I need?

The Titanic is 135 cm long; the Eiffel Tower is about 150 cm tall; the space station is around 60 cm across. Check the dimensions on each product page before ordering.
