Description

Offham House is a building with a mid-18th century front, though elements of the interior may date back to 1676, as evidenced by a sundial on the front dated 1676. The house is two storeys with an attic, and has seven windows, along with four dormers featuring segmental heads. It is faced with squared knapped flints and has an eaves cornice. The roof is hipped and slate-covered. The three central window bays project forward, topped with a pediment. This projection, and the flanking sections, feature long and short painted brick quoins. The windows are set in painted stucco architraves, with segmental heads and intact glazing bars. The rusticated stuccoed doorway is topped with a curved pediment, and contains a door consisting of six moulded and fielded panels. A sundial with the initials “NR” and the date 1676 is situated in the pediment. Rainwater heads, displaying the initials “ID” and the date 1749, are located on each side. The back or garden front is faced with flints and red brick laid in horizontal strips, and incorporates two projecting wings with canted ends. Inside, the house features a fine entrance hall and staircase.
