Osborne House (15) Including Wall and Outbuilding

Osborne House is a row of three houses, originally part of a 19th-century lace factory complex with offices, built in 1825 for George Freeman, a lace manufacturer. The houses are constructed of Flemish bond brickwork, with a slate roof hidden behind a parapet, including a return at the left end, and brick stacks. They have a double-depth plan.

The front elevation is two storeys and has a two-and-two-window configuration. The street facade features two widely spaced four-pane sashes above a wide three-light casement window with four-centred heads and a four-pane sash. The casement has rendered brick voussoirs and brick cills. To the left, within the attached boundary walling, is a good six-panel fielded 19th-century door set within a segmental relieving arch. Adjacent to the door is a small pyramid-roofed outbuilding with a single plate-glass sash window. The boundary wall also features a chamfer-brick string approximately two metres from the pavement, which is cut through by the door and window head. The left return has a four-pane sash window set within the parapet wall, and continues as a wing belonging to the adjacent No.14, a rendered house partially refronted in the mid-19th century. No.14 is two storeys and four windows wide, with one twelve-pane sash and three four-pane sashes at first floor, each retaining a residual keystone, and a tall French window with a keystone, and a large canted hipped bay with plate-glass sashes and central French doors at ground floor. A half-hipped porch with a three-panel part-glazed door is located at the centre, and a brick stack is positioned to the left. There is also a lower extension with four-pane and twelve-pane sashes. No.16 has replacement windows with splayed rendered lintels and stone cills, a 20th-century door with a rectangular transom-light, and a large opening to a semicircular arch leading to the North East Terrace. This area forms part of the front block of the former stocking-weaving factory and likely contained offices or other ancillary accommodation, connecting with Nos. 17 and 18.
