Walled Garden And Summerhouses, Mount Ulston

The Carriage House, Mount Ulston, is an early 19th-century building with additions from the mid-19th century. It comprises a two-storey, three-bay house with single-storey wings and a two-storey wing to the rear, creating a courtyard arrangement with outbuildings, including a former carriage house. The exterior is lime-washed sandstone rubble with ashlar dressings.

The South elevation is symmetrical, with a three-bay, two-storey central block flanked by single-bay, single-storey wings. A classically detailed timber porch with columns, a frieze, and a cornice is centrally positioned, sheltering a two-leaf replacement panelled door with a three-pane fanlight (previously four-pane). Eight-pane windows are located in the returns, and there are windows above each bay of the central block. An ashlar eaves course and quoin strips accentuate the central block.

The West elevation features a two-storey, two-bay rear wing, with a single-storey wing to the left. To the right is a block with bipartite windows at ground level; a single window is visible on the first floor to the left and a pair to the right. A projecting, single-storey canted bay with a tripartite window is located to the right, providing a return to the West pavilion. To the outer left is a single-storey wing containing a timber mullion window, with a blank range extending north, incorporating animal sheds that are open to the East.

The North elevation reveals the rear of the main house and a stepped, two-storey rubble range of outbuildings.

The East elevation shows the return of the single-storey East pavilion wing to the left. The entrance to the internal courtyard is obscured by a timber garage with a pitched corrugated-iron roof. A later two-storey outbuilding is situated to the right.

The building has twelve-pane timber sash and case windows throughout. The roofs are piended and steeply pitched, particularly on the main house, and covered with purple/grey slates. Stugged ashlar stacks are present, some of which have been rebuilt. The interior was not inspected in 1992.

The carriage house and stable range is located to the Northeast. It's constructed of rubble sandstone and includes a two-storey carriage block with a blocked segmental arch on the South side and a window above. A forestair, leading to a former hayloft, rises on the East side. A timber lintel protects a later machinery entrance on the North elevation, alongside two later windows in the upper stage. The former stable range extends West and has grey slates.

A coped rubble boundary wall runs along the road, adjoining the canted bay and curving to meet the house beyond the final bay to the West. This wall sweeps to a pair of square ashlar gatepiers with cornices on the South, and a further pair of later square gatepiers on the North.

To the South of the house lies a small, derelict walled garden enclosed by a coped rubble wall. A pavilion is situated in the East corner. A weatherboarded summerhouse, supported by three timber stilts, is in the North corner of the wall and features a pointed-arch window with diamond-pane and Y-traceried glazing. A further, piend-roofed stone tool-shed/summerhouse is in the East corner.
