Attached Stable Range to W of Capel Isaf

Capel Isaf is a building that includes an attached stable range to the west. The structure is roughcast with a slate hipped valley roof and roughcast stacks on the north and south ridges. It features bracket eaves and has a roughly square plan that was originally extended by one bay to the west in the 19th century.

The building stands two storeys tall with a two-window east front, featuring 12-pane sash windows on each floor, with the lower windows being larger. The south front originally had two windows with a central ridge stack, now featuring three windows: square 6-pane upper windows, a long narrow 10-pane window on the ground floor, and a 12-pane sash to the right. The added section to the left includes a four-12-4-pane first floor oriel and a small ground floor 12-pane sash. The north front has a horned 12-pane sash to the first floor left and a four-12-4-pane oriel above a door in a renewed open pedimental doorcase, with panelled reveals, a door, and an elliptical arched fanlight. The added section to the right has a 12-pane sash on each floor, while the west end wall features paired gables, with the right gable having a stack.

To the west, a colourwashed rubble low range connects to the hipped stable range, which is also colourwashed rubble with a ridge stack. The west lean-to has a two-storey front with two pairs of casement windows above, a stable door, a window, and a coach entry below, with a curved southwest angle. There is also a single-storey range to the west.

Inside, there is a broad oak staircase with scrolled tread ends, stick balusters, and a ramped rail. The two main rooms on the east have plain marble fireplaces and plain cornices. Two bedrooms above feature coved ceilings. The loft contains oak trusses, a tie-beam or collar-beam with queen posts, and internal walls on the west side have slate-hanging, indicating that the house has been extended since its original construction.
