Heavy Mining
Heavy Mining — 3,338 Piece Architecture Building Set
This is a building built for the shelf: Heavy Mining, engineered for proportion first and speed second. It runs to 3,338 pieces at 1:8 scale and takes around 10-16 hours to complete.
What Youre Building
The model is assembled as foundation, floor plates and façade, each finished as a separate unit before final assembly. At 1:8, the proportions are set for display rather than play.
Inside the Box
3,338 ABS bricks with consistent clutch power, sorted into numbered bags. A printed manual guides the build step by step. Every brick is compatible with the major building systems, so parts from an existing collection drop straight in. If a piece is missing or damaged, our spare-parts guarantee covers the replacement.
The Build
Rated expert, this is one of the harder builds we carry suited to builders who want to be pushed. Expect roughly 10-16 hours for a first pass at a steady pace. Working through the building in stages keeps the bench manageable, and sorting parts before you start saves time on a build of this size.

Finished, the building sits best as a centrepiece, or connected to other modular buildings to form a street.
