Description

Myrtle Hill is a two-storey house dating from around 1790, featuring three windows. The exterior is covered in colourwashed roughcast over rubble, with a plinth at the base. It has a moderately pitched slate roof with oversailing eaves, deep verges, and exposed purlins. The house has projecting end stacks, with the right end stack being shouldered.

The first-floor windows are 9-pane sashes (6 over 3) set in deep reveals, while the ground floor features 12-pane sashes with deep reveals and cambered heads. The central doorway has a broad six-fielded panel door, with the upper two panels replaced by new glazed sections. To the right end, there is a later outhouse made of colourwashed rubble masonry, which has an asymmetric pitched slate roof. This outhouse includes a single modern 4-pane window on the right, with stone voussoirs above, and a doorway to the left with a two-pane rectangular fanlight over a plank door.

To the left end of the property, there is a cartshed constructed from colourwashed rubble masonry, topped with a moderately pitched stone slate roof. It features a single loft window with a 9-pane sash (6 over 3) and a broad cart entry below, which has stone voussoirs and plank double doors. A former stable is attached to the rear of the house, which has a continuous outshot and three two-light casement windows. The back door of the outhouse is located at the extreme left.
