Designed by William Ralph Emerson, a prominent architect and relative of Ralph Waldo Emerson, this proud c.1884 Colonial Revival house is beautifully sited together with a c.1840 Italianate carriage house on two separate lots of almost a half an acre just outside of Harvard Square. Both the house and carriage house were extensively renovated in 1998 and have been updated periodically since. The main house offers finished living space on four levels and is full of original character and detail: decorative railings, Palladian and bow windows, high ceilings, quarter-sawn white oak flooring with decorative inlays, arched doorways and ceilings and pocket doors. Tucked away at the rear of the property, the 4-bedroom carriage house creates a European feel with its cobblestone courtyard, majestic Copper Beech and fenced rear yard with Cedars. This rare combination of premier location, large lot, house and guest house offers flexibility for guests, family, home office, studio or rental income
