The Bromley by Bow Gasworks site in east London comprises seven disused Grade II listed gasholders.

Seven gasholder frames will contain 10-storey blocks with six extra 15-20 storeys cylindrical buildings surrounding

Under plans drawn up by architect RSHP, these will be restored to incorporate many of the new homes within the cast iron structures.

The remaining homes will be built in higher rise surrounding cylindrical buildings echoing the gas holder homes.

A Section 106 legal agreement has to be finalised with London’s Newham Council, before work can begin on site in 2025.

St William’s ambitious scheme will involve a hefty upfront investment with the cost of temporary disassembly and restoration of the seven listed gasholders put at £80m alone.

The site is home to 7 of the last 19 listed gasholder remaining in the UK

This is before largely unquantifiable decontamination, enabling and ground remediation costs on the 9 hectare site.

Structural steel engineering specialists Craddys and Shepley have been closely involved in drawing up plans to reuse the cast iron gas holder structures, built between 1870 and 1882 for a cost of £300,000.

Both firms were previously involved in the project to dismantle, refurbish and re-erect the Gasholder No.8 guide frame at Kings Cross as well as the refurbishment and re-erection of the Kings Cross Triplets Gasholders.

St William submitted a hybrid planning application for the site, which also include the remains of two gas holders destroyed by the Luftwaffe in the second World War.

These will turned into a central circular lake and a community space covered with one of the gas holder iron frames.
