Under Construction City

Explore architecture around the world, then collect the buildings you actually visit — verified by location, tracked by city.

Under Construction City is your guide to the architecture around you — wherever "around you" is yet to happen.

Planning a trip? Browse the interactive map before you go, filter by city, architect, or style, and build a mental (or literal) list of buildings worth the detour. Switch to Timeline view to see a city's architecture unfold chronologically, or browse the Library for a curated grid — perfect for scouting a destination from your couch.

Already there? Collect it. Stand in front of a building in person and UCC verifies you're actually there, adding it to your personal collection — no guessing or self-reporting required. Track your progress city by city, see your most-collected architects and styles, and build a record of the architecture you've genuinely experienced firsthand.

Whether you're mapping out your next trip, a design student, an architecture tourist, or just someone who looks up more than most people, UCC gives you a reason to go looking — before, during, and after you get there.
