The DC property will be hotel only, the spokesman tells GlobeSt.com. Like the other 1 Hotels, it will contain a BR Guest restaurant under an agreement with restaurateur Stephen Hanson.

“Typically, Starwood Capital will hook up with a local developer in 1 Hotel locations,” the spokesman says, “although some developers may partner in multiple locations.” This hotel will contain 180 keys, and ground is set to break in mid-2008. The estimated construction cost is undisclosed. According to published reports, the partnership acquired the property for $15.5 million and will raze the existing building.

“Washington is home to some of the world's most important environmental organizations,” says Barry Sternlicht, president and CEO of Starwood Capital, in a statement. “It means a great deal to me personally to be able to demonstrate that we can combine a truly world-class, five-star living experience with environmentally responsible building and design under their watchful eyes.”

The New York City-based Natural Resources Defense Council is serving as an environmental advisor to the 1 Hotel properties. Sternlicht says the properties will donate 1% of profits to local environmental agencies guided by a steering committee, which has NRDC representation.

“For the vast majority of hotels, eco-friendliness means washing guests' towels less often,” says John Wood Bolton, Perseus' EVP, in a statement. “The 1 Hotel, Washington DC will demonstrate that luxury, comfort and impeccable service can co-exist with environmental sustainability.” A call to Perseus was not returned by deadline.
