Carr Hospitality has purchased the site of a former floral business at 1620 Prince St. in Alexandria, where it is expected to develop a new hotel near the King Street Metro station serving Old Town.

The company, founded in 2007, is the private hotel development and management company of the Carr family, builder of perhaps more of downtown Washington than any other company.

A Carr Hospitality partnership paid $4.85 million in May to the Alexandria Floral Co. for the lot of nearly one-third of an acre, according to property records. Repeated calls to Carr Hospitality President and Chief Operating Officer Hammad Shah and his staff were not returned.

A source familiar with the purchase, who spoke on the condition of anonymity because he was not authorized by the company to discuss the project, said Carr Hospitality plans to build a small hotel on the site, where Alexandria Floral operated a store until it was demolished for redevelopment during the real estate boom.

Carr Hospitality already owns hotel properties in Alexandria, including the 178-room Holiday Inn Hotel & Suites at 625 First St. and the 254-room Crowne Plaza Hotel Old Town Alexandria at 901 N. Fairfax St.

The Carr family, led by magnate Oliver T. Carr Jr., also renovated one of the area’s most famous and historic landmarks: the Willard Hotel, at 14th Street and Pennsylvania Avenue NW in the District, after it had been left vacant and was nearly demolished in the 1970s.

The Prince Street deal marks the second major hotel development project Carr Hospitality has landed since the financial collapse. Last year it inked a deal with developers of the District’s Southwest Waterfront, PN Hoffman and Madison Marquette, to build a four-star, 268-room hotel to be developed as part of the $2 billion Wharf waterfront development.

The D.C. hotel will be built in partnership with InterContinental Hotels Group, whose hotel flags include Crowne Plaza, Hotel Indigo, Holiday Inn and Holiday Inn Express. When the D.C. deal was announced last fall, Shah said the company hoped to take advantage of the waterfront location by acquiring boat slips that would allow guests to arrive after boating on the Washington Channel.

“Everybody gets on and off at the doorsteps of the hotel,” Shah said.
