174 Commonwealth is located on the south side of Commonwealth, between Dartmouth and Exeter, with 172 Commonwealth to the east and 176 Commonwealth to the west.
174 Commonwealth was designed by Lewis and Paine, architects, and built in 1893-1894 by building contractor Luther Moore Merrill, for speculative sale. He is shown as the owner on the original building permit application, dated July 27, 1893, and the final building inspection report, dated March 23, 1894.
Luther Merrill purchased the lot for 174 Commonwealth on April 5, 1893, from architect William G. Preston, buying the land as trustee under the will of his father, Silas Whiton Merrill, who also had been a builder in Boston and had died in April of 1890. William G. Preston had purchased the land on January 29, 1886, from Charles Whitney, who owned the Hotel Vendôme (in 1870-1871, William G. Preston had designed the original portion of the Hotel Vendôme for its first owner, Charles Wood, but did not design the large addition built for Charles Whitney in the early 1880s). The deed from Charles Whitney included language limiting the height and depth of any building erected at 174 Commonwealth so that it would not adversely affect the hotel.
The lot for 174 Commonwealth was part of a larger parcel which included a 14 foot lot at the east, between the Hotel Vendôme and 172 Commonwealth (with about six inches of the hotel’s western wall on it and the remainder an open lot), a 20 foot lot for 172 Commonwealth (built in 1885), and an irregular lot for 174 Commonwealth with a 22.01 foot frontage on Commonwealth and a 22.14 foot frontage on the alley. Charles Whitney had purchased the parcel on June 27, 1883, from William Tenant Hart, who had purchased it from the Commonwealth of Massachusetts on April 7, 1874.
