Our Take
Why we rate
this set
this set
BuyMyBricks editorial
This is a substantial build at 4,002 pieces — roughly 12 hours for most builders — with four distinct interior environments that reward exploration. The modular design works as both standalone display piece and part of the larger Icons collection, while the period detailing on the shopfronts and signage reflects LEGO's design maturity in 2017. Builders consistently report this as one of the Icons range's most satisfying builds, with the kind of architectural presence that justifies permanent shelf space.
The Set
What you're

Released in 2017, Assembly Square represented a significant step forward for LEGO's Icons range — a modular building that combined architectural detail with genuine play-ability across four storeys. The set struck the right balance between complexity and accessibility, making it instantly popular with experienced builders who appreciated its period streetscape authenticity and meticulous interior design work.
Assembly Square retired in 2024 and is no longer available in shops. What you're buying from us is a sealed, original example — sourced from verified suppliers and inspected before listing.
