Description

Delfan is a two-storey building constructed from colourwashed rubble stone and topped with a slate roof. It features a three-window front with 12-pane hornless sash windows and a central door. The windows have cambered heads and stone voussoirs. The original door has been removed to create recessed access to two flats. On the east end, there is a loft light and a 12-pane sash window on both the first and ground floors, located to the right.

At the back, there is an added two-storey rubble stone wing with a hipped roof facing north and a stone stack. This wing has a two-window range with 12-pane sashes, and a ground floor door on the left that includes an overlight. The ground floor door and window have brick heads, and there is an outshut at the rear.

It experiences an average of 26 freeze-thaw cycles a year, fewer than 72% of listed buildings. Of these, 13 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
