Fascinating insight into Madeira Terrace testing process

Residents have been given a fascinating insight into the technical testing process currently being undertaken on cast iron sections of Madeira Terrace.

The restoration, which began in November 2024, is one of the most ambitious and technical engineering projects we've ever undertaken.

Phase one, which focuses on the arches between the Royal Crescent steps and Concorde 2, is progressing well. All the cast iron skeleton has been removed and, as part of our commitment to protecting the heritage of the Grade II*-listed structure, taken to a specialist foundry for extensive testing and repair.

Insight offered into challenges of complex engineering project

Earlier this week, residents attending the latest in a series of community update events hosted by our contractor, Mackley, were walked through the cast iron assessment process and given an insight into the challenges presented by such a complex engineering project.

Members of the contractor and our project team outlined the need for such a thorough assessment and explained how the test results will inform how much of the original cast iron structure can be repaired and reused and how much, if any, will need replacing to ensure the terrace meets modern safety and engineering standards.

Positive news following testing

An initial round of testing at the specialist foundry has confirmed that many of the cast iron sections can be reused following repair work, although some require further investigation.

The meeting also gave residents the chance to see some restored smaller pieces of cast iron which have already been returned and learn more about the next steps in the ongoing restoration.

Determined to reuse rather than replace

Councillor Julie Cattell, lead member for Major Projects at Brighton & Hove City Council, said: “We’re determined to reuse as much of the original, century-old structure as possible, but this does present challenges to our team.

“For example, even after cast iron elements have been repaired, a thorough and comprehensive level of stress testing is required to prove they can be safely reused in line with modern standards. 

“This can take time, but it is in line with our heritage-focused approach to this project. We want to restore this beautiful structure, not simply replace it.

“The cast iron structure may have stood for more than 100 years, but we do need to take that extra care and time to make sure every element is suitable to retake its place in the terrace.”
