The Triangle Building

The Triangle Building, a 140,000-foot-tall, 250,000-square-foot building, is in a premier Denver location on 16th Street Mall and immediately adjacent to the Denver Union Station.

The Triangle Building features 15,000 square feet of ground floor retail with 212,000 square feet of Class A office space on floors two through 10. The building also has two levels of underground parking and features a unique triangular shape to fit the approximately 0.9 acre, zero lot line site. Included in the project scope was the Wewatta Plaza, a public plaza/walkway that forms an important part of the connection between Union Station and the Pepsi Center.

A few key aspects make it even more pleasing to the eye, like having 20% more window offices than a traditional building due to the building’s curtain wall and distinctive shape. The project team also realized the importance of supporting local economy and sustainability. The project was built using regional steel and cement, while recycling steel, wood and gypsum on-site.

Additionally, Saunders self-performed all the concrete work — over 13,000 cubic yards between caissons, footings, slabs, cores, decks, curbs and pads.

Giving the illusion of a continuous sheet of glass perched atop an angular, modern base, the Triangle Building is nothing short of a design marvel. It is one of downtown Denver’s signature landmarks. Sitting on a triangle parcel site, the building is center to the converging approaches of Wewatta Street, 16th Street Mall and Old Wewatta Plaza. This building, with three angles meeting the busy cross sections, provides an individual identity.
