LOVED (8)

01Exceptional interior detail in every room, including a dance studio with a functioning piano, a dentist office, a photography studio, a patisserie with a push-button cookie oven, and a flower shop
02Impressive curved corner construction using small incremental bricks spanning all three floors
03Intricate roofline featuring creative use of hammers and excavator shovels as decorative elements
04Classic green baseplates that give the street scene a distinctive, period-correct feel
05Easter eggs and references to previous modular sets rewarding longtime collectors
06Central fountain plaza that adds an open-square feel rarely found in other modulars
07No stickers; all detailing done with printed bricks

CRITICIZED (6)

01Garage door pieces used as bakery windows, which some builders found fiddly and difficult to seat properly
02Baseplates connecting the two buildings feel loosely attached, raising handling concerns for a large model
03Some window treatments considered missed opportunities for more ornate curtain or element variety
04Instruction booklet arrived unprotected in some copies and suffered damage
05Outdoor grill area considered bland relative to the richly detailed interior rooms
06Music store above the cafe lacks a sign, which feels incomplete

Ecosystem

10251 Brick Bank — Assembly Square is substantially larger and more impressive, serving as a fitting tenth anniversary release to the Modular Buildings theme

10246 Detective's Office — Assembly Square is significantly more substantial than its immediate predecessor

10182 Cafe Corner — The café in Assembly Square uses similar design elements (white and yellow striped awnings, radial sign) but features substantially altered and more refined details

10243 Parisian Restaurant — The photographer minifigure may be a friend of the artist from this set; roof terrace chairs echo similar color choices from Parisian Restaurant

"this is one of the most complex sets Lego has ever released it has a lot of new parts part recolors and references to all of the old Modular Buildings"

Key Pros

✓Extensive references to prior modular sets integrated nicely and classy
✓Brings Café Corner elements to those who cannot afford or obtain the original
✓Excellent flower shop design with signage, windows, and transparent green elements that create colored light effects

Key Cons

✕Unroofed outdoor kitchen/cooking area on upper floor looks incomplete and looks like it's missing a roof - doesn't feel right aesthetically
✕Excessive bagging/sorting process psychologically frustrating - many bags with same number, bags within bags, progress feels farther from finish line as more bags are opened
