Co-Operative Society Offices, 64 Dalziel Street, Motherwell

The building at 64 Dalziel Street, Motherwell, is a three-storey with attic tenement block originally designed as offices for the Dalziel Co-operative Society in 1894 by Alexander Cullen. It was later converted into residential apartments in 1992. The building exhibits an L-shaped plan with a prominent domed corner tower.

The exterior is constructed of red ashlar sandstone, featuring a cavetto moulded dividing band between the first and second floors, a cavetto eaves course, and a cornice. A blocked and balustraded parapet tops the building. The principal corner elevation showcases a canted corner bay. Round-arched windows are present, accentuated by projecting keystones, flanking Ionic columns, and quoins to the first floor. The second-floor windows feature a stugged architrave and projecting cill, with a pediment over the central window and segmental pediments over the flanking windows. An inscribed plaque reads "1894 DALZIEL CO-OPERATIVE SOCIETY," flanked by garland husks and guttae, with small, architraved windows on either side. A heavily moulded segmental pediment sits at the centre of the parapet, displaying a projecting relief sculpture of a ship’s prow in the tympanum and a freestanding figure of Justice bearing scales and a sword at its apex.

The corner tower consists of a single stage, octagonal structure with vertical timber boarding and a copper cupola. It features a moulded plinth course, architrave, and projecting cornice. Pilastered, multi-pane windows are set within square, lugged architraves.

The Northwest elevation, facing Scott Street, is nine bays wide. A slightly advanced bay at the far left has plain, rectangular windows and projecting quoins to the first floor. The second bay from the left displays a moulded architrave with a projecting keystone and quoins to the first-floor window, and a projecting pediment above the second-story window, along with a small architraved attic window. A Venetian window is located on the first floor of the third bay, extending down to the dividing band, with Ionic pilasters, a projecting keystone, and quoins. A small architraved attic window is flanked by low-relief garland swags. Bays four through eight mirror the details of the third bay, and the outer right bay mirrors the third bay.

The Northeast elevation, facing Dalziel Street, is six bays wide and mirrors the Northwest elevation. Low-relief panels here depict science, literature, and art.

The rear elevations are harled with regular fenestration, including an octagonal stair tower with a pyramidal roof. The side gable ends are also harled.

The majority of windows are plate glass sash and case, with double-glazing to the rear. The roof is a concealed pitch, covered in grey slates with lead flashing and rooflights. Brick coped gable end stacks are present.

Internally, the building was converted into modern apartments in 1992. Many original classical timber fittings have been retained.
