Bath-House, South Terrace, Hatton House, Edinburgh

The terrace and fountain at Hatton House in Edinburgh date back to the late 18th century. The structure features a rubble-built battered wall with a central curved bath-house projection and square pavilions on either side.

The pavilions are two-stage, square-plan structures topped with ogee roofs. The ground level is finished in rusticated ashlar, while the upper level is made of rubble with harl-pointing, accented by ashlar dressings, impost and dividing cornices, raised quoins, an eaves band, and channelled margins. The north pavilion has an entrance to the first floor from the terrace and a lower floor entrance from the south side.

The west pavilion has a large round arch opening at the center, featuring a fluted console keystone and a projecting impost cornice on either side. There is a tripartite entrance with a central door flanked by two now-blinded windows, and a large oculus in the tympanum above. A projecting, moulded string course runs along the pavilion, with a window at the center of the first floor. The south return has a blocked window at both the ground and first floor. The west elevation is inaccessible but is believed to have a similar arrangement to the east elevation.

The north elevation of the east pavilion has a ground-level door with a rusticated architrave. Inside, there is a wooden roof, a 12-pane sash and case window in the south wall, and a fireplace in the west wall. The east pavilion mirrors the west pavilion's arrangement but features a round arch and a console keystone. It has a ruinous forestair against the south wall leading to the upper garden, supported by an arch buttress on the east side. The first floor has windows, although they have been replaced, and there is a door at the center of the north elevation with a rusticated architrave. The pavilion has French casement windows and a slate ogival roof, though the finials are broken off.

The bath house projects semi-circularly from the center of the terrace wall and is built of rubble with ashlar dressings. It features a door at the center of the south front set within a battered opening, with windows on either side, both within heavily splayed surrounds, and a niche above each opening.

Inside the bath house, the walls are finished with smooth render and feature a segmental vault. There are stone benches lining each wall, with niches above. A round bath made of ashlar, measuring 10 feet in diameter and 4 feet deep, is located at the north end under a rusticated arch, although no fittings remain.
