Stewart Park Depot

This is a mid-1860s stable block with lodges, originally part of Marton Hall, which was demolished in 1960. It is now used as a parks department depot within Stewart Park, Middlesbrough. The building is constructed of red brick with blue brick and sandstone bands, and has Welsh slate roofs.

It comprises a large U-shaped range with east and west lodges flanking an entrance to a courtyard. The style is High Victorian Gothic. The west lodge has a six-bay south front, with a projecting gabled two-bay centre. It features four-light windows with Caernarvon-headed lower lights and segment-headed upper lights, set within hollow-chamfered surrounds and mullions; these windows now have mid-20th century casements. A three-light mullioned attic window is set within the gable. There is a tablet with a raised monogram above the windows in the centre, and arch-braced collared bargeboards with arch-braced hammerbeams and turned finials. The steeply-pitched roof has bands of fishscale slates, partly-renewed transverse ridge stacks and early 20th-century raking dormers.

The east lodge is similar, with mid-20th century garage doors in two of the bays. It has a tablet dated 1864 in the centre and original gabled roof dormers with matching bargeboards. A central, tall wooden lantern has cusped bell openings with shaped louvres under gablets and a pyramidal spire with a ball finial and weather vane. Courtyard elevations are partly obscured by mid-20th century lean-to sheds.

The north stable range is 13 bays long, with a slightly projecting gabled three-bay centre, including a Caernarvon-headed doorway under a segment-headed overlight, flanked by four-light windows where only the upper segment-headed lights are visible. A three-light mullioned window is set in the gable. The Bolckow arms and crest are displayed between the floors. Similar bargeboards are present. Similar doorways are in the third and eleventh bays, flanked by similar two-light windows, with round openings containing patterned radial hit-and-miss panels in segment-headed recesses. These are flanked by buttresses. Windows in the fourth and fifth bays have hit-and-miss panels under casements. All openings have hollow-chamfered surrounds. Paired dormers are located over the third and eleventh bays. The east stable range has similar detailing and two dormers.

The eight-bay west coach-house range has a segmental arcade with renewed boarded doors and similar paired windows. One bay is blind. A stack with a chamfered plinth, clasping pilasters, pilaster strips and a chamfered cap is centrally located. Outer faces of the stable block contain similar detailing. Mid-20th century sheds in the courtyard, and stables and bothies to the north and east are not considered to be of special interest.
