This is an American Foursquare home, a conservative style developed in the late 19th Century as a reaction to the overly decorative Victorians popular in that period. The most characteristic Foursquare conventions include the broad covered front porch, the deep eaves, the wide bay window, and the attic dormers, each directional and each with a hipped roof.
Foursquares are all rather massive and block-like, but vary in their spare use of ornament, including details from Colonial Revival, Arts & Crafts, or Prairie Style. This home has certain Colonial leanings, specifically in its trim work, both within and without, but the expression of rafter tails would be a corollary of the Craftsman style, which emerged in the same period.
The owners decided to keep the building in its most traditional, and thus original, state. We maintained as much original fabric intact, and made modifications only as needed to advance the 1911 home into the next millennium, such as the expanse of the kitchen / dining area into a more open plan, and the addition of a new wing extending to the south, containing a laundry and half-bath.
