Dolenog was built 1837-39 and extended c.1900 and again c.1946. The building is now L-plan; 2-storey.

The original part is of local rubble with freestone dressings including quoins, plinth and cill band. It has a hipped slate roof with bracket eaves, and stone chimney stacks with neck bands. Architecturally the ivy clad garden front is the most important; 3-bays with a deep and broad central bow. There are 15-pane sash windows to the ground floor opening onto a stone flagged terrace.
