Starting in 2001, father-and-son developers Mickey and Kyle Zeppelin began developing a campus of buildings meant to serve as offices, ateliers and residences for Denver's creative class. They started by renovating the 28,000-square-foot former Yellow Cab dispatch center — hence the name TAXI — before adding several new structures to the group and rehabbing other existing buildings. The latest structure to come on line is the sleek Drive building, set behind the famous landscraper (a horizontal skyscraper) called TAXI 2. Drive, designed by Stephen Dynia Architects with Barker Rinker Seacat Architecture, is very cool, with jutting forms covered in dark metal cladding that's set against raw concrete. The artful pattern of slit windows and window walls creates a contemporary-looking constructivist composition.
