This is the B.B. King House in Falmouth, Mass.
No, not THAT B.B. King. This one, built in 1881, belonged to B. Baylies, Esq., and adjoined his lumber yard.

A successful businessman and owner of several properties, King eventually sold this house and lumber business to James Cameron.
Cameron was a Scotland native whose business supplied frame, finish and builders’ hardware. The business was later moved to Locust Street and became the Wood Lumber Company, which is still in business today.
The house itself was originally a simple Victorian with Green Revival style, with decorative roof brackets and a bay window. A wrap-around porch with brackets and turned posts, along with the two story tower, were added later.
