20, Tenby Street North

20 Tenby Street North is a manufactory built around 1890, with some alterations made in the late 20th century. The building is constructed of red brick, featuring blue brick and ashlar stone detailing, and has a concealed flat roof.

The structure has an irregular L-plan layout situated on a street corner, with a vehicle entrance leading to a narrow rear yard on Tenby Street. The elevation facing Tenby Street North consists of 3 and a half bays, rising three storeys above a basement, and is set on a chamfered blue brick plinth that includes flat-headed basement windows. The ground floor features a doorway at the left end, flanked by five windows, all with semi-circular arched heads. The windows have roll-moulded and rebated surrounds, stone cills within an ashlar cill band, and a continuous hood mould with foliated stops. The first floor has paired windows with segmental-arched heads positioned between wide brick piers. The upper floor includes triple light openings with moulded brick cills and roll-moulded flat lintels, all beneath a corbelled eaves band.

At the west end, a half-bay breaks forward, forming the first part of a faceted splay to the corner, with each facet containing a single ground and first floor window, plus a pair of narrow upper floor windows that match the main elevations. All windows have late 20th-century frames.

The Tenby Street elevation features an advanced half-bay on the left, a wide central bay with triple lights on the ground and first floors, and four lights on the upper floor. The vehicle entrance bay on the left breaks forward slightly, showcasing a wide semi-circular arch-headed double doorway with ashlar jambs that rises from the blue brick plinth. This doorway is topped with a hood mould featuring foliated stops, and the planked and panelled double doors are adorned with decorative wrought iron grilles at the heads.

This late 19th-century manufactory is located in an area of the Jewellery Quarter predominantly filled with industrial buildings, which collectively exhibit the distinctive architectural and planning characteristics typical of Birmingham's manufacturing district, now recognized for its international significance.
