Located in the heart of Denver’s burgeoning Central Platte Valley district, Paradigm River North's unparalleled location is bounded by the 16th Street Mall, the new Union Street 17th Street Transit Mall, the new Downtown Denver Bus Terminal, and Wewatta and Chestnut Streets. Paradigm River North is immediately adjacent to Union Station, the $480 million federally-funded public/private partnership project transforms Union Station into Denver’s premier multi-modal hub for light rail, commuter rail and bus transit. Union Station is currently estimated to serve 200,000 daily passengers. In addition to its strategic location in the center of Denver’s largest transportation gateway, Paradigm River North offers instant access to the Highlands Neighborhood, Riverfront Park, Confluence Park, and countless amenities within the Lower Downtown district.

This amenity rich neighborhood is one of the most vibrant urban areas in the country. In addition to pioneering Denver’s craft food scene, RiNo is regarded as one of Denver’s top entertainment and cultural hubs with some of the city’s best restaurants, breweries, galleries, shops, bars, music venues, and more.

Designed by Denver-based Tryba Architects with Saunders Construction as the general contractor, the building represents a well-considered response to the formerly industrial neighborhood’s evolution, reflecting the historic character of the neighborhood with a brick façade and large factory-style windows.
