This Grade II Listed building (No.1392773)1 comprises three loose boxes with a boiler room at the south end. Before their current conversion, they formed an equine Turkish bath installed at Heath House by Matthew Dawson soon after he arrived in 1866. The three rooms were the hot room, the shower room, and the cooling-room. The baths were, famously, used by the celebrated jockey Fred Archer himself, as well as for the horses, though he included his own Turkish bath in the house he built at the time of his marriage.

The three doors shown in the photo above are problematic. There would normally be only a single door into a Turkish bath, with internal interconnecting doors between the three rooms. This seems to be confirmed by the bricked up archway (shown below) between two of the rooms.

So two possible scenarios suggest themselves. First, the building was originally a set of three loose boxes which Dawson had converted into a Turkish bath by sealing two of the existing three doors and forming two internal connecting archways. This would then have easily been re-converted later into the existing three rooms.

Second, and less likely, the Turkish bath was built as such at the time, and the three doors added later. Further research is clearly necessary to arrive at any firm conclusion.
