Our heritage-first approach to restoring Madeira Terrace has been boosted by the results of recent cast iron structural testing.
The restoration work, which began on site in November 2024, is one of the most ambitious and technical engineering projects we’ve undertaken.
We’re keen to reuse as much of the existing material as possible, including the cast iron and soil, and repairing rather than replacing the retaining wall.
The aim for restoration that’s as authentic as possible also helps limit the scheme’s environmental impact by prioritising repair and reuse of the cast iron over recasting.

Earlier this year, sections of the cast iron structure, which were removed as part of the first phase of restoration, were sent to a specialist foundry for testing and repair. The testing is to prove that the structural cast iron can be successfully repaired and reused.
Following a first round of tests that were inconclusive, additional testing of the cast iron components was required. The team behind the project has now confirmed the latest data from the testing demonstrates that the original structural cast iron can be reused.
While this testing has taken slightly longer than initially planned, the results have been welcomed by both the council and the recently established Seafront Development Board, the independent body charged with providing insight and guidance to the council as we look to continue the revitalisation of the seafront.
Repair and reuse century-old cast iron
The results will allow us to confidently repair and reuse much of the century-old cast iron structure during the initial phase of restoration.
The environmental savings of repair compared to casting new replacements are significant. The casting of iron generates about 8 tonnes of CO₂ emissions for every tonne of cast iron created, whereas repair is expected to generate less than an eighth of this.
Across the whole structure, this would be equivalent to the carbon cost of powering over 2,000 homes for a year, based on average UK household emissions.
Lift steels arrive on site
There was more good news on site this week, with the arrival of the first sections of lift steels, which will form part of a new, fully accessible lift providing people with easy access from the pavement on Marine Parade to Madeira Drive.
Once finished, the lift will be a key part of the opening stage of restoration and provide people with much needed access to the seafront and the growing number of businesses on Madeira Drive.
Most of the steels for the lift will have arrived on site by Christmas, meaning residents will be able to see visible progress on the lift structure.
Incredibly technical restoration
Councillor Jacob Taylor, our Deputy Leader and Cabinet Member for Finance and City Regeneration, said: “We know people are understandably eager to see the first phase of Madeira Terrace completed and open to the public to enjoy; this is an incredibly technical restoration which will take time and require patience.
“We’re determined to reuse as much of the structure as we can – to restore rather than replace. We know it is what many of our funders expect from the project and is also central to our commitment to being heritage-led in this first phase.
“The structure is more than 100 years old, so repairing and restoring is not without its challenges and there may be times, such as with our recent cast iron testing, where this approach takes slightly longer. Taking time and care to lovingly restore this beautiful and iconic structure is the right thing to do.”
Excitement building around the project
Lord Bassam, who chairs the Seafront Development Board, agreed. He said: “Madeira Terrace has the potential to once again be the jewel in the crown of this city’s seafront and it is fantastic to see the first phase of its restoration progressing.
“It is absolutely appropriate that every effort is taken to restore this amazing structure.
“I’m looking forward to the first sections of repaired cast iron being put back in place and for residents and visitors to see this ambitious restoration really starting to take shape.
“With the lift steels arriving on site, there is a real excitement building around the project’s progress.”

Backstory and Technical foundations of the Madeira Terrace Heritage‑Led Restoration
Madeira Terrace, the iconic iron‑clad promenade that stretches along Brighton’s seafront, was opened to the public in 1905 as part of the city’s early‑20th‑century push to modernise its coastal amenities. Designed by the City Engineer’s office under Sir John Whitty, the structure combines a series of cast‑iron columns, wrought‑iron balustrades, and a concrete‑filled retaining wall that supports the promenade above the tidal zone. Over a century of exposure to salty sea spray, freeze‑thaw cycles and the encroaching sea level left the terrace with extensive corrosion, structural cracking, and an urgent need for intervention.
In 2018 the local authority classified Madeira Terrace as “at risk” on the Heritage England Register, prompting a series of feasibility studies that highlighted two competing priorities: preserving historic fabric while meeting contemporary accessibility standards. The resulting “heritage‑led” approach, adopted by Brighton & Hove City Council in 2022, mandates maximum reuse of original materials, rigorous environmental impact assessments, and the integration of a fully accessible lift that links Marine Parade to Madeira Drive. This beliefs aligns with the UK’s National Planning Policy Framework, which encourages the reuse of historic building components to lower embodied carbon.
The cornerstone of the current works is the groundbreaking testing of the century‑old cast‑iron columns at the specialist foundry of A. J. Smith & Co. in Sheffield. Advanced non‑destructive evaluation (ultrasonic pulse velocity, radiography) and metallurgical analysis verified that more than 85 % of the original columns retain sufficient integrity for repair and re‑use.The repair methodology employs “laser welding of steel pins” and “cold‑spray aluminium alloy” to address surface pitting, allowing the original cast iron to remain in situ. This strategy, compared with recasting new sections, reduces embodied CO₂ by an estimated 7.5 t per tonne of iron, translating to a carbon saving equivalent to the annual electricity consumption of roughly 2,000 UK homes.
The new lift,scheduled for completion in early 2026,is a modular steel‑frame platform engineered to meet BS EN 81‑70 accessibility standards. It will feature a 12‑person cabin, dual‑door operation, and a battery‑back‑up system designed to keep the lift functional during power outages. By anchoring the lift to the existing cast‑iron columns where feasible, the project not only preserves visual continuity but also minimises new foundations, further curbing excavation‑related carbon emissions.

Is the heritage‑led restoration of Madeira Terrace safe for the public?
Yes. All repair and lift installation works are carried out to current British Standards (BS 6229 for historic ironwork, BS EN 81‑70 for lift accessibility, and BS 8105‑2 for pedestrian safety). Independent structural audit reports, submitted to the Seafront Development Board, confirm that the repaired cast‑iron columns meet or exceed the original design load capacity, and the lift includes redundant safety systems such as emergency brakes, door sensors, and a battery‑backed power supply. Ongoing post‑completion monitoring will verify performance over the first five years.
What is the projected cost of the Madeira Terrace restoration over time, and how does reuse of cast iron affect the budget?
The total programme budget is forecast at £18.6 million (2024‑2027).Reusing the original cast‑iron columns avoids the need for new steel replacements, delivering an estimated £2 million saving on material procurement and an additional £1 million in reduced carbon‑offset fees. The cost per repaired column averages £12,500, compared with £18,000 for a brand‑new fabricated substitute. these savings,combined with the lower embodied carbon,keep the project within the council’s £20 million financial envelope while meeting heritage‑led objectives.
