Description
Gelli Graean is a large farmhouse that stands three storeys high and features a three-window range, with lower service buildings aligned at either end. The structure is built of rubble stone and has slate roofs with gable end stacks. The long, symmetrically arranged three-window range is slightly offset to the left. The central entrance is flanked by small-paned sash windows, and there are three similar windows on the first floor. The low attic storey has two-light casements positioned just below the eaves.
