The house is aligned NE-SW, and built into slightly rising ground so that the farm-buildings, which lie to its rear, are at a higher level.

The house is rubble stone, limewashed to the front elevation; graded slate roofs (replaced with modern slate to rear) with chimneys on the original gable ends, and the gable end of the added bay. Main chimney at L hand gable is considerably bigger. Two-storeyed, 3-window range originally, with an additional bay added to the R.

Rear of extension has gabled porch to loft, with arched door giving direct access to granary, to R.

The farm buildings form a courtyard at the rear of the house, and at a higher level. The yard is closed by a wall linking gable end of domestic range with the cow-house which is parallel to the house. The rear wing of the house is attached to the stable and barn. These are of rounded rubble with coped gables to random slate roofs. Big barn door (with aligned doorway onto field at rear), with 2 tiers of ventilation slits to its L. Stable in L hand bay has doorway to R, and window on each floor beyond. Rough stone lintels to all openings.

In the yard, at R-angles to the barn, the later cowhouse has a single window to the L, at R-angles to the barn, the later cowhouse has a single window to the left, and original doorway towards centre. R hand bay has been altered, and has modern infill to R of another doorway.
