Trolley Garage/Firehouse

Location: Philadelphia, Penn., USA
Architect: OnionFlats

In 2007 this structure, which started out as a trolley maintenance garage, then became a firehouse, was transformed to its third identity as home. The 5,000 square-foot space now features an observation deck over the living room, reclaimed lumber, and the attic was opened into a mezzanine.
