Farmington is the clubhouse of a country club that also includes adjacent housing. The clubhouse was erected c. 1760–1780 for Francis Jerdone and was a substantial brick side-passage-plan building with the principal entrance to the north. In about 1802, while occupying the White House, Thomas Jefferson designed for its new owner, George Divers, a distinctive octagon-ended wing, fronted by a massive Tuscan portico and nine round windows, for the east side. The original drawings at the Massachusetts Historical Society indicate that the wing was subdivided into two tall spaces with triple-sash windows. When the Jefferson interior burned in the mid-nineteenth century, the wing was converted into a single large space with two fireplaces. Subsequently other additions were made to the houses. Around 1927 the property and extensive outbuildings were converted into a clubhouse for a new country club and more additions made. The Jefferson section was restored by Frederick Doveton Nichols (c. 1970), but it still retains the midnineteenth-century single space.
