Roslyn, the William Grosvenor House (1890-91 et seq.; William Ralph Emerson, architect):

A spreading and impressive 2½-story house with a substantial, high, yet low-slung hip roof enveloping the carefully modulated rectangular-plan mass. Circular-plan conical-roof towers dominate the façade and frame the shed-roof porch that stretches between them. Regularly placed 6-over-1 and 8-over-1 windows punctuate the contained mass, whose symmetry is broken only minimally by the staircase window on the western tower, the octagonal-plan projection at the northwest corner, and the four stout stone chimneys, that at the eastern end of the south elevation with a round-arch opening.

Grosvenor (1833-1906), was a Providence-based businessman whose wealth had been accumulated in textile manufacturing, notably the Grosvenor-Dale Company in Thompson, CT.
