The Triangle Building is a signature landmark of downtown Denver (Colorado, USA). The 42-metre-high frontages give the illusion of continuous sheets of glass. This striking three-cornered building is situated at the intersection of three busy streets. Built in 2015, it was acquired for the Union Investment portfolio in 2017.

Triangular landmark

The unusual design of the new residential block turned the awkwardly shaped site into an attractive location.
