Salem loft in Charles Bulfinch-designed building asks $425,000

The 1,600-square-foot, two-level Unit 3 at 5 Derby Square in Salem is in a converted warehouse that federal-style pioneer Charles Bulfinch designed in the second decade of the 19th century.

The 2-BR, 2-BA is an airy affair, with two brick-walled levels and a second-level balcony behind a striking balustrade. There’s also a private deck out back and the main bathroom was recently remodeled.

The spread is asking $425,000 through Keller Williams.
