LEGO 10255 Assembly Square

Released 2017 · 4,002 pieces · 9 minifigures · Modular Buildings

LEGO Assembly Square (10255) was released in 2017 as part of the Modular Buildings theme, with 4,002 pieces and 9 minifigures. That makes it the 2nd largest of the 22 Modular Buildings sets in the catalog. Released in 2017, 9 years ago, well past the two-to-three-year run most LEGO sets get, so it is almost certainly out of production.
