Gasholder No 8, former Bromley-by-Bow gasworks

This gasholder was built between 1880 and 1882 to the design of engineer Vitruvius Wyatt for the Gas Light and Coke Company. The contractors were Westwood and Wrights, with construction carried out by William Bourne Wright.

The structure is primarily composed of cast-iron columns and composite wrought and cast-iron girders forming the guide frame. Each girder has a decorative cast-iron web between two wrought-iron angles at the top and bottom. The gasholder is approximately 23 meters high and 62 meters in diameter.

The circular guide frame consists of two tiers of 24 cast-iron columns connected by horizontal cast and wrought-iron girders, classified as Type 14 in Tucker’s typology of gasholders. The lower columns are fixed to substantial moulded cast-iron pedestals, featuring fielded panels and oval plaques. These plaques bear the inscriptions "WILLIAM BOURNE WRIGHT/ ENGINEER," "WESTWOOD & WRIGHTS/ CONTRACTORS," and the date of completion. The lower columns are cast as Roman Doric columns with moulded bases and capitals. Atop each column is a junction box designed as an entablature, consisting of a Doric frieze with triglyphs beneath a cornice. The cornices are detachable castings, concealing the structural connection between the lower and upper columns. Lower girders feature decorative filigree ironwork. The upper tier of columns is in a simplified Corinthian order, each topped with a plain frieze. The column proportions follow classical principles, transitioning from the heavier Doric order at the base to the lighter Corinthian order at the top. The upper girders have an interlocking circle motif. Guide rails are attached to the inside edge of each column, facilitating the movement of the wrought-iron roller carriages upon which the telescopic bell of the gasholder rose and fell with gas volume.

According to planning legislation, the bell and tank themselves are not considered to possess special architectural or historic interest. However, any proposed works that could affect the character of the listed building may still require listed building consent, determined by the local planning authority.
