Former Domestic Hatting Workshop, 66a Market Street, Denton

This is an early 19th-century domestic hatting workshop, constructed of handmade brick with a slate roof. The building is approximately square, measuring 4.33 metres by 4.36 metres. It has two storeys.

The workshop is built of handmade bricks in an irregular bond, topped with a double-pitched slate roof and a brick ridge stack on the south gable wall. The west elevation features an entrance doorway towards the right, with a first-floor window above, set within a slightly segmental brick lintel. The doorway has a deep, segmental brick lintel and a boarded overlight. The first-floor window has a projecting stone sill and segmental brick soldier lintel, though it has lost its window frame and is currently boarded over. Two first-floor windows are set off-centre to the left on the north gable wall, with a single ground floor window beneath the right first-floor window, partially obscured by a modern timber lean-to shed. All windows have stone sills and deep, slightly segmental brick lintels. The first-floor windows have unhorned, six-over-six pane hung sashes. The ground-floor window has a cross-frame timber frame. The south gable wall is blank. The east wall is also blank, showing some scarring at ground-floor level suggesting a former projecting wall that has been cut back.

Internally, a projecting brick chimney breast sits in the centre of the south wall, with a fireplace currently obscured. A timber staircase, with treads and strings but no handrail, is against the east wall, rising towards the south gable. Deep timber joists support a timber floor between the north and south walls, with trimmers in front of the chimney breast and stairwell. The first-floor windows have simple timber architraves. The room was previously ceiled, but the ceiling has partially collapsed. The roof structure comprises two deep purlins, narrow rafters, and a ridge purlin.
