The Upton Residences in downtown Denver is on track to deliver 461 condos next summer and marks the city’s largest condo project since the Spire came online with 496 units in 2009. In between, came The Coloradan, which delivered 334 condos at Union Station in 2019. Aside from those, and a few smaller luxury projects, metro Denver hasn’t seen much new condo construction, which developers attribute to a highly litigious environment over construction defects in Colorado.
