29, Warstone Lane B18

29 Warstone Lane is a High Victorian Gothic jewellery works building constructed around 1870. It is a tall three-storey structure with a four-bay red brick facade featuring polychrome detailing in gault brick, tile, and painted stone dressings. The building has a gault brick plinth and a stone and gault brick plat band, which includes tilework and gault brick sill bands on the upper floors. The eaves are shallow and corbelled with a parapet.

The windows on the ground and first floors are grouped in a three-centred arched arcade, with moulded edge jambs and richly carved acanthus leaf ornamentation on the imposts. There are roll moulded drips, gault and red brick voussoirs, and stone keys. The second-floor windows feature stiff leaf corbels as imposts supporting drip moulds over triangular arches. The plate glass sashes on the second floor are divided into three pointed head panels by vertical glazing bars. The entrance is located in the left-hand ground floor bay and has a blind tympanum with a trefoil design.
