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. Building Specs Architect: Skidmore, Owings & Merrill, LLP Cost: $42,000,000 Size: 215,000 SF Schedule: 18 months Meet the Development Team The Solution: “In 2004, Blake Real Estate, Inc. entered the “age of green” by collaborating with Casey Trees, D.C. Greenworks, and others to build the District’s first high-elevation green roof at 1425 K Street, NW. The 3,500 square foot roof was one of the largest green roofs in the nation’s capital, and the first on a commercially-owned property in the city at that time. The project is a good example of a public-private partnership. It's not easy being a guinea pig. If Blake hadn't been willing to investigate and listen to the facts about a technology that is little known in the D.C. area, a variety of complications might have become insurmountable obstacles. When presented with the facts—the private and public benefits green roofs provide—Blake was willing to put its trophy building behind, or rather underneath, the technology.” LAND Online Name* Phone Email* Property Address (if applicable) Not Applicable 1150 Connecticut Ave NW 1120 Connecticut Ave NW 1025 Connecticut Ave NW 1730 Rhode Island Ave NW 1425 K St NW 1800 G St NW 1100 L St NW 2100 K St NW 1111 18th NW 1122 Connecticut Ave NW Blake Industrial Park Message* 1150 CONNECTICUT AVE NW, WASHINGTON, DC 20036 © BLAKE REAL ESTATE, 2017, ALL RIGHTS RESERVED.
