Trecarrel Mill Cottage

Trecarrel Mill Cottage is a disused cottage that underwent mid-17th century remodelling of an earlier building, with later additions and alterations. Part of the structure was demolished around 1946. It is constructed from limewashed, roughly coursed slate-stone rubble with cob above, and features 20th-century weatherboarding on the right end. The roof is made of corrugated iron and is half-hipped to the right. The cottage has a two-room plan, which originally extended to the right but was truncated in 1946. It was originally one storey, but the eaves were raised to create a one-storey and attic structure, with the original roof line still visible on the left gable end.

A raking eaves dormer in the centre contains two multi-paned 18th-century casements with crown glass and L-hinges. There is a similar casement with H-L hinges to the lower left, and a four-panel door with a rectangular barred overlight under a gabled hood to the right. An integral slate-stone end stack is located on the left side.

Inside, the ground floor features a 20th-century spine partition wall and a 19th-century cast-iron range in the fireplace, which has a chamfered segmental wooden lintel. There is an inset panelled wall cupboard to the left, with another in a corresponding position in the attic. The roof has a chamfered collar truss design in three bays, plus a half bay at the truncated right end, and retains original horizontal thatching spars.
