In keeping with Denver’s spirit of urban renaissance, the tower design synthesizes elements of both the past and the present. In both program and execution, the building asserts a contemporary presence: interior appointments reflect refined urban sensibilities and a post-tensioned cast-in-place concrete structure expresses today’s construction methods. To integrate the new building within the historic center of downtown Denver, aesthetic inspiration derives from nostalgic urban skyscraper precedents, the form eroding symmetrically as it ascends. Verticality is emphasized through the juxtaposition of curtain-wall glass and pre-cast concrete piers: the piers articulate the length of the building, and the glass form emerges from the pre-cast skin, elongating the building at the upper floors and resolving in a distinctive 75-foot-tall communications spire. Dark-bronze anodized window mullions and metal spandrels further heighten the vertical effect of the tower, drawing the eye upward.
