15, Sandhill

No 15 Sandhill is a bank building constructed in 1880 by John Burnup & Sons for Lambton & Co. It is designed in a free classical style and features sandstone ashlar with a rock-faced plinth and a graduated dark slate roof with ashlar dressings. The building has four storeys and three windows, with the outer windows paired. The ground floor, which has been remodeled in 1990 by Waller & Sons for Lloyds Bank, features a rusticated design with a rock-faced plinth.

On the left side, there are internal steps leading up to wide double panelled doors that are recessed in hollow reveals of an arch with an elliptical head and a plain overlight. To the right, three round-arched windows have plain glazing with transoms. The door and two right windows feature a faceted key and rusticated voussoirs, while the left window has a moulded head resting on an impost string supported by scroll brackets leading to a first-floor balcony.

Fluted composite giant pilasters define the bays on the first and second floors and support a full-width entablature with a modillion cornice. The outer first-floor windows have wide pediments, while the central window features a segmental pediment, all supported on scroll brackets with stone balustrades resting on the floor string. The central balcony projects on brackets and has been partly repaired in brick.

The third floor has square-headed windows in architraves that rest on the second-floor entablature, with shallow pilasters featuring crocket capitals defining the bays and supporting a plain top entablature with an eaves gutter cornice. The balustraded roof parapet, which has been partly repaired in brick, is interrupted by a central tripartite casement with plain pilasters and the date 1881 in a segmental pediment topped with a palmette finial. Pedimented dormers in the outer bays rise behind the parapet. The mansard roof has stone gable coping and tall ashlar end stacks.
