• Do not begin any work, or buy materials until after you have received confirmation your project has been approved.

History

The Back Bay was originally a tidal body of water, used for mill operations. In the mid-19th century extensive landfilling began, resulting in over 450 acres of usable land by the 1880s. The Back Bay was an early planned fashionable residential district, based on Baron Haussmann’s plans to remake Paris. As the tidal flats were slowly filled in, beginning at the edge of the Public Garden and extending westward, residential construction advanced on filled-in lots as they became available. As a result, Back Bay, when viewed in block sequence, illustrates the changing tastes and stylistic evolution of American architecture over the course of the mid- to late 19th and early 20th centuries. Commercial development started on Boylston Street around 1880, and on Newbury Street in the early 20th century, in some cases adapting existing row houses.  You can learn more about Back Bay through this brochure on the history of the area.
