4 Tower Knowe, Hawick

4 Tower Knowe in Hawick is a former bank building designed by David Rhind in 1852, with an extension added in 1935. This three-storey, five-bay structure features a palazzo style and a piend roof, showcasing fine Classical detailing. The three central bays are advanced, while a later recessed bay is located to the outer right. The left side has a basement level that overlooks Slitrig Water. The principal elevations are made of polished yellow sandstone ashlar, while the rear is constructed from tooled yellow sandstone ashlar and some render.

The building has a base course, a fascia band with a dentilled cornice, and a floreate wallhead frieze with dentils. The deep, modillioned eaves cornice adds to its grandeur, along with raised long and short quoins. Round-arched windows on the ground and first floors have raised guilloche margins, flanked by pilasters with scrolled consoles and lion-head capitals that support dentilled cornices. The second-floor windows feature shouldered architraves. Access is provided by three stone steps leading to a two-leaf, timber-panelled front door in the right-hand bay of the advanced central section, which has a semicircular decorative fanlight and is flanked by columns supporting a Doric entablature. There are also three stone steps to a two-leaf, timber-panelled secondary door in a plain architrave at the outer right bay.

The ground and first floors have plate glass in timber sash and case windows, while the second floor features 4-pane glazing in similar windows. Stained glass can be found in the ground-floor windows at the rear. The building is topped with a grey slate roof and has four corniced ashlar wallhead stacks with circular buff clay cans.

Inside, the former banking hall includes a glazed inner door with a double fanlight, a herringbone-pattern parquet floor, decorative cornices, and moulded architraves. Some timber panelling surrounds the windows, and the raised northern section is accessed through a broad basket arch supported by Tuscan Doric columns on deep pedestals, leading up three steps. The basement contains some black-and-white glazed ceramic wall tiling and large, built-in metal cabinets.
