The LEGO Modular Buildings line is the most consistent appreciator in modern LEGO. Released annually since 2007 — first under the Creator Expert label, now under Icons — each set is a 16-stud-wide detailed urban facade designed to connect with the others into a continuous LEGO street. The series has produced enough flagship-tier releases that "modular" is now a recognized collector category in its own right.
This guide is the reference: every release, what makes the series tick, and how to approach collecting it.
The format
Every Modular set shares a common spec:
- 16 studs wide. Sets connect along the long edges to form an unbroken city block.
- 32 studs deep. Standard Modular footprint.
- Three or four floors visible at the front, removable for interior detail access.
- Detailed interiors — modulars are designed to be opened up and looked into, not just viewed from the street.
- 2,000–4,000 pieces typical, $200–400 retail.
The shared spec is what makes them collectible — they line up. A 10-Modular collection is roughly 10 feet of continuous LEGO street.

One Modular per year, with rare exceptions. Assembly Square (2017) was the 10-year-anniversary set — larger than usual, and includes a hidden tribute brick to Cafe Corner.
Why Modulars appreciate
Three structural reasons:
Limited production runs
Each Modular runs for 2–3 years before retiring. After retirement, the set is gone for good — LEGO has never re-released a retired Modular. The aftermarket is the only source.
The collector lock-in effect
People who own 5+ Modulars want a complete set. The harder it gets to acquire missing pieces, the more they're willing to pay. This drives sustained demand for retired sets even as years pass.
Display value
Modulars look genuinely good displayed together. They're not "LEGO sets on a shelf" so much as a continuous miniature world. That display appeal sustains aesthetic interest across decades.
Current secondary-market values (rough order)
Sealed-set values move with market conditions; this is the rough order of magnitude as of recent years (always check BrickLink "Last 6 Months Sold" for current data):
- Cafe Corner (2007) — the original; sealed sets command 4-figure prices, often $1,500–3,000+ depending on condition. The single most valuable retired Modular.
- Market Street (2007) — technically not a Modular but often grouped with the series; very limited release; similar high-end values.
- Green Grocer, Fire Brigade, Grand Emporium — second-tier early Modulars; typically $400–700 sealed.
- 2010–2014 Modulars — typically $300–500 sealed.
- 2015–2020 Modulars — typically $200–350 sealed for retired ones; current production at MSRP.
- 2021–current — at or near MSRP, depending on production status.
How to start a Modular collection
Two paths:
Forward path — start from the current year
Buy each new Modular at MSRP as it releases. Easy, no premium pricing, and the collection grows linearly. Downside: you'll never own the older Modulars without paying secondary-market premium.
Backward path — start from a specific older Modular you love
Pick the Modular that visually appeals most, accept the secondary-market price, and add forward and backward from there. Downside: an irregular collection that's missing both directions until you fill it in.
What NOT to do
- Don't buy the Modular series in unsorted bulk. Several Modulars contain similar piece types (windows, doors, building plates) but the printed parts and stickers are set-specific. Buying mixed bulk doesn't get you a "complete-enough" Modular.
- Don't pay scalper prices for current-production Modulars. If a current Modular is $400 on eBay but $200 at MSRP and "out of stock," wait. LEGO restocks current sets.
- Don't buy heavily damaged-box Modulars expecting to resell. Sealed-box value drops sharply with box damage. For your own collection, box damage is fine; for resale, it isn't.
- Don't underestimate space. A 10-Modular collection takes roughly 10–12 linear feet of shelf. Plan accordingly before committing.
The space problem
Modulars are space-hungry. Solutions adult collectors use:
- Floor-to-ceiling LEGO city wall — shelves at multiple heights creating layered streets. Maximum visual impact, requires dedicated wall.
- Single shelf, rotated display — only display the favorite 4-5 Modulars at a time; rotate seasonally.
- Box storage for some, display for others — keep most Modulars sealed-and-stored as collector items, build only your favorites.
Building tips specific to Modulars
- Build with the floor-removal in mind. Modulars are designed to lift floors off for interior access. Don't glue or "improve" connections that LEGO designed loose.
- Sticker application matters. Modulars use detailed stickers for signage, posters, and printed details. Apply slowly and deliberately; Modular stickers crooked-stick are visible from across the room.
- Don't rush. Modulars typically take 8-15 hours; pace per the flagship pacing guide.
