We built our LEED-certified community to align with the values of the people that call Boulder, Colorado home. Environmentally conscious, active, sustainable. Another major selling point we factored for? Access. Located in the Gunbarrel Business District, Apex 5510 offers instant access to employers in Gunbarrel Business Park, and major landmarks and businesses like The University of Colorado, Folsom Field, IBM, Covidien, HP, Spectra Logic and GE are just minutes away.
