Description

Castell Coch, Exmoor House, and The Malt House form an unusual terrace featuring consistent later 19th-century details with a slight Arts and Crafts influence, evident in the use of small red clay tiles and vernacular casement windows. This terrace may have been altered around 1880 from an earlier range.

The terraced house is whitewashed roughcast with a roof covered in red pantiles and topped with crested ridge tiles. It has a red tiled pentice roof over a continuous ground floor projection. There are red brick end stacks, with the left stack rendered. The building is two storeys high and has a three-window range; the upper windows are pairs of casements that just break the eaves and feature catslide roofs. The ground floor projects and has a tiled roof, with a large 4-pane sash window to the left and an unusual 5-bay glazing arrangement to the right, consisting of four windows and a central door, all with three-sided heads and console brackets between. The door and some windows have 20th-century plate glass. There is a southwest rear wing with a slate roof and an end stack.

The interior was not available for inspection at the time of the resurvey in December 1999.
