Although prepared to develop the building on a speculative basis, Hines landed its first tenant last month. Van Gilder Insurance Corp. preleased 57,000 sf on the building's second and third floors. The company will be relocating from 700 Broadway. Jamie Gard and Nathan Johnson of the Frederick Ross Group have the leasing assignment.

Designed by Hartman-Cox Architects, 1515 Wynkoop will be clad in brick and glass, the goal being to blend in with neighboring structures. In addition to the office space, the building will have 27,000 sf of street-level retail and below-grade parking for 425 vehicles. The project has been pre-certified LEED Silver by the US Green Building Council.

The Hines project is one of several contributing to a revitalization of Lower Downtown. In addition to the redevelopment of Union Station and the surrounding area, two other office building projects are in the works. Opus has plans for a three-building, 400,000-sf mixed-use office, retail and residential complex at 1400 Wewatta St., across from Pepsi Center and Multi-Employer Property Trust announced it is planning to develop a 335,000-sf, 18-story office building near the Millennium Bridge at 1900 16th St., which is next to its 285,000-sf Legacy Plaza development.
