Here at Curbed we just love buildings that have been converted from one purpose into another. Like when a church or an old fire station becomes a set of condos. But hiding out in Langdon is a building that started out life as a firehouse, was converted into a church and then was zoned for residential use. Be still our beating hearts! A building that was both a church and a fire station? We can hardly contain ourselves. This fixer-upper is now for sale for $700,000, after being originally listed for $1M. Click over for the fascinating history of the building.
