The Lapham Building, located at 280 - 290 Westminster Street and wrapping around the neighboring Tilden-Thurber Building to Mathewson Street, was designed by Hoppin & Ely Architects and built for the heirs of Benjamin Lapham in 1904. The building originally was home to the Mutual Benefit Insurance Company and has had various office tenants throughout the years. The building had been largely vacant since the late 1990’s, until the completion of the recent redevelopment which added 35 residential units on the upper floors and 17,000 sf of commercial space.
