Egg-End Boiler, Ballochmyle Creamery, Haugh

The Egg-End Boiler, Ballochmyle Creamery, Haugh, is a complex of buildings with a fascinating history, primarily dating to circa 1911 as part of a major rebuild, though with earlier elements from circa 1890. The most distinctive feature is a tall range with a central European profile, characterised by a deep-eaved and swept gambrel roof and a large, bell-cast, iron-crested axial ventilator. Other ranges and additions are generally plainer but sympathetic in design and materials. The buildings are mostly white-harled with red ashlar details, featuring small-paned glazing patterns, gabled slate roofs with broad eaves, long rooflights, and red ridging tiles.

A tall range near the west, its gable stepped in height among three gables (with a lade access underneath), appears to date from circa 1890 and is among the earliest surviving buildings on the site. A panelled red brick wall is partially visible on the south flank of this range, while the west gable is harled, although some underlying stonework, including a lade archway, is visible and likely reused from pre-1890 structures. The 1911 rebuilding includes a three-storeyed centre block arranged in a T-plan around the earlier 1890 east gable. Originally, a low, flat-roofed series of ranges with round-arched openings extended around this centre block, though these have since been heightened, with original openings still visible at the east end and within later additions on the south. An unroofed court or lightwell is located near the lade, featuring a gated archway at the east.

Inside the tall range, concrete-arched floors are supported by steel beams and plain cast-iron columns. Walls are mostly white-glazed brick or tile, with blue trim. The roof incorporates distinctive curved steel trusses, as do other early pitched roofs. Surviving elongated cast-iron Corinthian columns are found in the original engine room, situated in the southeast corner. Formal gardens, appearing early 20th century in style, were originally laid out to the east, in front of the manager's house. While these have been partially spoiled by a modern shed, rock-faced garden walls, gatepiers with wrought iron gates, fragments of stone terraces beside the house, and a small, rock-faced pavilion remain. A similar structure, potentially a powerhouse or summerhouse, built on piers over the river, and a gardeners' shed with glass house are located to the south.

The Egg-End Boiler, an unusual survivor, is situated beside the house; it features rivetted iron plates raised on brick piers.
