Challenge Works

CHALLENGE WORKS

Former edge tool manufactory, now workshops. Built around 1880 for Louis Osbaldiston and Co, saw and file manufacturer and merchant. Red brick with ashlar sandstone dressings, gable and ridge stacks and slate roof covering.

The building follows a U-shaped courtyard plan, with a frontage range to Arundel Street and rear yard enclosed by parallel rear workshop ranges.

The Arundel Street frontage is asymmetrical, comprising three bays across three storeys above a basement. A massive ashlar surround frames a central vehicle entrance with a shallow arched head, keyblock and cornice. The opening contains tall 8-panel double doors and leads to a setted covered way. To the right is an arch-headed loading doorway with double doors, and to the left a single doorway. Flanking the entrance are tall ground floor window openings, with 2 and 3 lights respectively, each within ashlar stone surrounds with sash frames. Stone sills form bands at each level, with windows diminishing in height at ascending levels. Basement lights at footway level repeat this pattern but are boarded up. Between the first and second floor windows a plaque bears incised lettering reading 'CHALLENGE WORKS'. Bracketed eaves cornice runs between elaborate moulded ashlar kneelers to the gables.

The rear elevation features 6 over 6-pane sash windows on stone sills to the upper floor, with a 2-storey lean-to extension to the centre bay. Single storey workshops with monopitch roofs, front wall stacks, multi-pane casement windows and vertically-boarded doors extend north-westwards from the frontage range on both sides of the yard. A 2-bay, 2-storey range with pitched roof extends from the north-east workshop range, with ground and first floor openings.

The interiors retain known extant features: within the frontage range, a staircase from a passage doorway on the south-west side, and a first floor office with partitioning and built-in cupboards. A ground floor hearth to the north-east room contains a 19th-century cast-iron range, and a first floor hearth with plain surround lies in the south-west room. The south-west workshop range retains in-situ stamping machinery and line shafting.

Challenge Works was built as an edge tool manufactory with workshops, office and warehouse, but rapidly evolved into a multi-occupancy site. By 1888 an electro-plating company shared the site. The Goad Fire Insurance plan of 1896 identifies various trades operating on site, with tool forges positioned behind the street frontage range, which itself was identified as office and warehouse.

Challenge Works is a significant survival from Sheffield's once densely populated manufacturing quarter. It stands alongside the earlier 19th-century 'Little Mesters' workshops at No. 92 Arundel Street and the associated master's house at No. 92A. Together they form a now-rare ensemble of small and medium-sized metal-working factories characteristic of 19th-century Sheffield, when its products and skills acquired international reputation.
