Furnace House including forecourt walls, railings, gates and overthrow

This is a three-storey and basement town house, largely rebuilt in the late 20th century, but retaining its front facade. The house dates from the 18th century, and is constructed of painted cement render with raised stucco quoins, stone sills, and a fine ashlar porch. It has a slate roof.

The porch is accessed by four stone steps and features two Corinthian columns with carved capitals and moulded bases supporting an entablature and cornice. A 20th-century door is set within the porch. Matching cast iron railings, dated 1761, flank the steps; these are of a column-on-vase design with square bases, large column newels with ball finials, and handrails that ramp down to posts. The basement level has nine-pane timber sash windows with stone sills on either side of the porch, with lower, similarly styled six-pane sashes to the outer bays. The ground floor and first floor windows are renewed 15-pane horned sashes, while the second floor has matching 12-pane sashes. A plain stone course runs above the second floor, beneath a parapet with stone coping.

The forecourt is enclosed on two sides by rendered walls with ashlar coping and raised piers. Two large pineapple finials, on stepped and swept pedestals respectively, are positioned at the front. Slightly inward of centre on each side is an ashlar niche with plain raised piers, an arch surround, and a keystone. Each niche incorporates a seat with a panel set between the piers. Remarkable cast-iron railings are set on low ashlar walls across the front. These railings are fluted column on turned pedestal and have gadrooned urn finials. Two sets of four linked rails, each with a cap and a larger urn finial, are positioned on either side of the piers, with an ashlar plinth projecting forward beneath each set. The inner gateposts are cast-iron columns with similar rails, set on high pedestals and featuring entablature blocks carrying sets of four grouped rails with a cap and four urn finials, from which springs a twisted iron overthrow incorporating a scrolled iron lamp bracket. The entablature blocks are inscribed "1761" and "M. Busteed fecit." The gates themselves have similar rails with urn finials above ramped-down top rails, with open ironwork forming a concave-sided lozenge pattern with a central circle in the lower section.
