Peter Scott's Factory, 7-11 (Odd Numbers) Buccleuch Street

Peter Scott's Factory is an extensive mill complex on Buccleuch Street, built in phases from around 1816 through to 1923. The main frontage to Buccleuch Street comprises three distinct sections arranged across a roughly triangular site that extends to the rear with numerous storage blocks, weaving sheds, a tall chimney and boiler house.

The earliest section forms a 10-bay block to the left, constructed in two stages with the 7 right bays built first and the 3 left bays added later. It is built in squared, coursed whinstone with polished yellow sandstone ashlar dressings to the street elevation, some of which has been painted. The rear is whinstone and yellow sandstone rubble. The ground floor contains a shop accessed by 4 marble steps, and a pend entrance approached through a broad, 2-leaf, timber-boarded gate. The upper storeys are lit by tripartite stone-mullioned windows with projecting cills. The building rises to a ridge roof with tall blocking course and modillion cornice, supported on 2nd-floor and attic band courses above a base course.

The central 14-bay section dates from 1910 and was designed by Charles Brown, with the 2nd floor and attic added by James Pearson Alison in 1923. This section is built in squared, coursed yellow sandstone with polished ashlar dressings to the street, with yellow sandstone and whinstone rubble and brick to the rear. The ground and 1st floors have stop-chamfered margins, while the 2nd-floor windows are recessed behind pilaster mullions. The principal features are continuous strip windows divided by stone mullions and 4 evenly spaced flat-roofed dormers. At ground floor there is a raised door to the left of centre and a round-arched window to the outer left. A full-height, M-gabled wing projects to the rear. The eaves are dentilled and there are cill courses throughout.

The right section is a tall, single-bay gabled block also by James Pearson Alison from 1923. It has a quadripartite window at ground-floor level, tripartite windows to the upper storeys, and a Diocletian window at attic level rising to a broken pediment. The street elevation is yellow sandstone ashlar with channelled pilaster quoins, while the western side elevation is rendered and the rear is yellow sandstone rubble.

The principal block is roofed in grey slate with metal ridge and ridge vents, and ashlar-coped skews. Stacks are coped ashlar with octagonal buff clay cans. The windows throughout are predominantly plate glass in timber sash and case frames, with 6-pane fixed glazing and tilting upper panes to the right section. Cast-iron rainwater goods run throughout.

The tall octagonal tapered chimney is constructed of painted brick with banded detailing. At its base stands a roughly rectangular-plan boiler house in tooled, squared yellow sandstone, with 3-leaf timber-boarded doors and various brick and timber structures mounted to its roof.

A 3-storey roughly rectangular-plan canteen and stock-room block adjoins the rear of the eastern end of the Buccleuch Street block on a diagonal line. Extensive single-storey weaving sheds with linked piended roofs extend further to the rear. The stock-room block is rendered brick, and both structures are lit by strip skylights throughout. They are roofed in grey slate with metal ridges and ridge vents.

The interior contains regularly spaced cast-iron columns with simple capitals supporting ceilings throughout most of the buildings. Late 1950s decoration is evident in the ground-floor boardrooms and offices at No. 11 Buccleuch Street, featuring light wood panelling inlaid with strips of dark wood, with some panelling also present to the 1st-floor offices.
