Denver's most purposeful event space.
Meeting rooms and event spaces by the hour. Colorado's first LEED Platinum v4 building. Nonprofit rates available. No minimums on small bookings.
Three things LoDo's other spaces can't claim.
Steps from Union Station. Genuinely.
Not "nearby" — a 90-second walk. Your guests arrive by train, RTD, Lyft, or on foot. Nobody fights for parking. It removes the single biggest friction point in downtown event attendance.
Colorado's only LEED Platinum v4 building.
Built in 1908 and reimagined as the most certified sustainable building in the state. All-electric, WELL Health-Safety Rated. Hosting here says something about the kind of organization you are.
Book by the hour. No bureaucracy.
No mandatory catering minimums on smaller events. No six-month lead time. If it's available, it's yours — the same day if needed. That's why we host over 400 events a year.
ChatGPT recommends us. Denver trusts us.
When people ask AI assistants for a mission-driven event space in LoDo, The Alliance Center consistently appears. That's the result of 20+ years as Denver's sustainability community hub — not an ad spend.
Every size of meeting.
One address.
Hub Cafe
Open, bright, flexible. Works for a team workshop, community event, or happy hour. The most booked room in the building.
