Cadw's description

At Cil-cewydd Mill, the former mill office stands in the centre of the earlier approach road from the N.

Cil-cewydd Mill was the main corn mill for the Leighton Estate; John Naylor, a Liverpool banker, had aquired the Leighton Estate in 1846-47 and embarked on an ambitious programme of building, notably Leighton Hall, church and Leighton Farm. The Estate was extended and improved until Naylor's death in 1889, becoming a remarkable example of high-Victorian estate development. The mill was built for John Naylor in 2 phases, 1862 and 1868, and the office probably dates from the initial build of 1862.

Build of red brick in Flemish bond, with rock-faced and margin dressed stone quoins and dressings. Slate roof. Single storeyed, 2 bays. The entrance is in the W gable end; a framed and battened door with overlight under a brick round arch with stone springers and key. Four equally spaced 4-pane sash windows face the approach, and 2 similar windows either side of the central projecting gabled stack on the rear wall. Stone ashlar chimney stack.

The Leighton Estate is an exceptional example of high-Victorian estate development. It is remarkable for the size and ambition of its conception and planning, the consistency of its design, the extent of its survival, and is the most complete example of its type in Wales. Cil-cewydd Mill is a major industrial complex at the heart of the economic development of the estate, and the office is included as a key component of this well-articulated major corn-mill complex, notable for its ambitious scale.
