20, Lower Lux Street

No. 20 Lower Lux Street is a mid-19th century building that features two shops with domestic accommodation. It is constructed of stucco on studwork, with slate hanging on the first floor of the Pound Street front and a rag slate roof on the front elevations. The building has two brick end stacks and includes a reused 17th-century crested clay ridge tile on the Pound Street range, along with a cast-iron ogee gutter.

The building has a double-depth corner site plan and is two storeys high with a three-window range. The original windows are 9-pane hornless sashes. The ground floor has two complete mid-19th century shop fronts: a double 4-light shop front on the left with a central glazed door flanked by splayed sidelights, panelled stall risers, end pilasters, and a fascia with a moulded cornice; and a 3-light shop front towards the right with a glazed door on its left, a plain stall riser over a plinth, and similar detailing to the other shop front. The Pound Street return features a two-window range with 9-pane sashes on the first floor. The interior has not been inspected.
