Workshop Range, Castle Toward

The walled garden to the north of Castle Toward dates from the 1820s, likely designed by David Hamilton, and was remodeled around 1921 by F W Deas. The earlier east, west, and south walls are made of rubble and feature stepped pediments and a round-arched pedestrian gate with ornamental wrought-iron work on the south wall.

The north wall was remodeled around 1921 and includes a bowed section of layered dark grey schist with engaged pillars at the corner angles. A glazed garden loggia breaches the wall at the center, topped with a bellcast roof and a sculpture of a wolf and lamb on the ridge. There is a glazed link between the loggia and an octagonal glasshouse to the north.

To the south of the walled garden, there is a formal water garden with associated hard and soft landscaping. In the northeast corner of the walled garden, remnants of an earlier 18th-century building, possibly the old Auchavoulin House, can be found, with various carved stonework fragments incorporated into a round-arched opening to the east.

The walled garden to the north, constructed around the 1920s by F W Deas, is a large, square-plan structure made of dark grey schist stone. It features a double staircase with decorative carving in the style of Robert Lorimer that leads to a pedestrian entrance in the west wall. Above the doorway is a carved panel depicting the Greek god Pan surrounded by grape vines, with elaborate fruit and flower carvings on the rounded pier caps and carved lions flanking the doorway. There is a simple doorway on the south wall and a single-storey lean-to range on the north wall, which has multi-pane glazing in timber frame windows and a grey slate roof.

The former glasshouse and workshop range, built around 1930 by F W Deas with heated glasshouses designed by engineers Mackenzie and Moncur, is arranged in a U-plan configuration of garden offices, workshops, and former heated glasshouses. This structure predominantly features dark grey schist stonework. The south wall has three large, fan-lit, round-arched windows in the central section and stepped gables to the north (which formerly had a glazed roof), flanked by half-pitched slate-roofed stores. There are foundations for a former greenhouse and remnants of a heating system to the south, along with a tall chimney stack to the right. Further workshops and office wings extend to the east and west, completing the U-plan layout, with timber windows and grey slate roofing.
