1425 K Street

Total renovation of a 12 story, 300,000 SF office building with four levels of underground parking into a trophy class property.  The building was re-massed with a new precast concrete and granite façade, aluminum and glass curtainwall, and a bronze clad storefront.  The main lobby was reconfigured with Anigre wall panels, bronze trim, and marble floors and walls.  Mechanical, electrical, and life safety systems were completely replaced.  Deteriorating garage slabs were demolished and replaced.  A roof top terrace and fitness center were added to the building.

The Challenge

In 2003 Blake completely renovated one of its flagship properties located at 1425 K Street. As part of this effort the company sought to showcase the creative potential of the company through a sustainability initiative. They approached their clients to understand what was being done around the city to promote sustainability and came away with the understanding that the idea for a green roof on an office building had never been successfully implemented in D.C. After much discussion they settled on the idea of planting a living garden on the roof despite the obvious challenge in inventing the wheel. If they were to be successful it would require a new approach to sustainable design strategies and a commitment to the environment that went beyond established practices.
