[1] The Philbrook House is a two-story wood-frame structure, three bays wide, with a hip roof and a granite foundation.

The roughly square main block has a 1+1⁄2-story ell extending from its rear, joining it to a large barn/carriage house, all of which are of similar vintage construction.

The main (east-facing) facade has a center entry sheltered by an elaborate hood, and is flanked by projecting polygonal bays with wood panel sections below the windows, and a bracketed cornice above.

[2] The property on which the house stands was purchased in 1858 by Samuel Delano Philbrook, a native of Gilead who was a successful cattle dealer and later president of a local bank.

In the 20th century the property served as a time as an inn and as a health center, and now houses a retail establishment, with a living space above.
