Berkeley Investments is the latest developer to tap into the potential of redeveloping Boston parking garage properties to meet demand for more office space.
The Boston-based company notified city officials this week it’s proposing to add two floors of office space atop the Stillings Street garage in Fort Point.
The 50,000-square-foot addition would sit above six stories of parking and two floors of offices in the building on the edge of the massive Seaport Square development.
The expansion “will provide prime office space in the heart of the Innovation District,” according to a letter from attorney Peter Kochansky of Goulston & Storrs to the Boston Redevelopment Authority.
Other changes include conversion of some ground floor space to retail use and installation of windows on the northern side of the building which overlooks Q Park.
Office rents have skyrocketed in the neighborhood in recent years as the brick-and-beam converted warehouse space has become popular with tech start-ups such as Zipcar and LogMeIn. The 414,000-square-foot Thomson Reuters portfolio, a 10-building complex, sold in April for $183.5 million to Dallas-based Invesco, $63 million more than its 2007 sale to Waltham-based Crosspoint Assoc.
