Description

A corner building for the collection

Where earlier Modular Buildings sat in a straight row, Assembly Square wraps around a corner, so the finished model closes off a street junction rather than extending a line of shopfronts. That makes it a natural centrepiece if you already display other sets from the series side by side. Structurally the building is dominated by Light Bluish Gray and Dark Bluish Gray brickwork, with white window frames and cornices and black roof and façade details keeping the street scene coherent rather than clashing.

645 unique parts across four levels

The shopfronts on the ground floor – including a florist and a café – sit below flats and workshops on the upper storeys, each level fitted out with its own furniture, signage and small details rather than repeated pieces. With 645 unique parts, there is very little duplication across the model, which is part of why the build takes time. The full parts list on this page breaks down every colour used, useful if you want to check availability before buying or plan a repair after a rebuild.

Nine minifigures and a street-level scene

Nine minifigures populate the model, enough to fill the shops and pavement with shopkeepers, residents and passers-by rather than leaving the street empty. A small plaza in front of the building, complete with a bench, a lamppost and planters, gives the figures somewhere to stand beyond the interiors. For anyone who displays or photographs their builds, the corner shape opens up more viewing angles than a flat façade, from the ground-floor shopfronts up to the balconies.

Is Assembly Square worth the build time?

At around 4,000 pieces, this is not a weekend project, and it rewards builders with patience and shelf space rather than beginners. If you already own other Modular Buildings, the corner shape gives your street layout a natural endpoint; if this would be your first modular set, it is worth trying a smaller entry in the series first to see whether the format suits you before committing to a model this size.
