One of the most perplexing and hated buildings in Downtown Boston is the former Fiduciary Trust Building at 175 Federal Street. The building exudes 1970s Corporate Modern design, focusing on large floor plates with minimal intrigue at the exterior. Sadly, Boston has quite a bit in the Financial District, but many are getting facelifts! This 17-story tower was designed by The Architects Collaborative (TAC) which was founded by Walter Gropius, one of the pioneers of Modernist architecture. The building is hexagonal with all six sides being of different lengths. TAC had to construct a tower that avoided large utility lines, the MBTA tunnel, and street patterns, which resulted in an “urban flower” which cantilevers over the narrow base. As of 2020, plans have been unveiled that show the building will be updated and a glass-enclosed lobby installed.
