Farm building and hay-barn at Ty-coch

The farm building and hay-barn at Ty-coch is a single-storey structure likely used as a cowhouse, built from rubble with slate roofs, although part of the roof on the cowhouse has been replaced with corrugated iron. The layout includes a walled yard on the southwest front and an open-sided hay-barn attached in line, with a later cowhouse set at right angles on the southwest side. The hay-barn consists of three bays that are now open to the northeast, featuring tall square piers that support the wall plate and roof. Originally, the barn was also open to the southwest before the second cowhouse was added.

Inside the barn, there are two trusses of principal rafters that are half-lapped at the apex, with low-set lapped collars supporting two tiers of purlins. The cowhouse has softwood tie beam trusses with raking struts, and the soffit is fully torched. There is a good manger with a hayrack above it.
