By 1897, many brownstone mansions, similar to those constructed in the Back Bay region, were built in Kenmore Square, starting from along Charlesgate West and moving westward down Beacon Street and Bay State Road.  Single family dwellings #7 through #63 Bay State Road were already constructed, filled the entire block, and continued down Bay State Road past the intersection with Raleigh Street.  On Beacon Street, development was progressing in four groups with all single family brownstone dwellings.  At the corner of Beacon Street and Commonwealth Avenue stood a triangularly shaped residence which was the first oddly shaped building constructed in Kenmore Square.  Brownstone dwellings were also present in two groups between Charlesgate West and Kenmore Street and in one group between Commonwealth Avenue and Brookline Avenue.  The Belvoir apartments were built at the corner of Beacon Street and Raleigh Street and a final group of brownstones were being erected behind the apartments between 58 and 80 Bay State Road.  Thus, the land use in the square at the turn of the century was mostly residential.  In addition, it is most likely that construction began at the western portion of the region since this was closest to the Back Bay which had just been developed.  Moreover, the gaps of empty space between the newly constructed brownstones were probably due to a series of different owners gradually developing separate pieces of land simultaneously.  The Sanborn map above from 1897 ⁵ indicates the location of the dwellings in the square in addition to the open space.
