A section of Madeira Terrace could reopen to the public as soon as summer 2026.

Restoration is set to get underway for 28 of the 151 arches of the Brighton landmark in the summer, with the work expected to last between 18 and 24 months.

Along with the restoration of the arches, the first phase of the project will include a new lift, the full replacement of the upper deck with a waterproofed deck, refacing and regreening the Green Wall, reinstatement of the planted verges at Madeira Drive level and seating to the upper and lower decks.

Initially built as a covered promenade and viewing platform to attract tourists, Madeira Terrace is the longest cast iron structure in Britain - stretching more than half a mile.

A total of 40 arches had been due to be restored in the first phase of the renovation, but the project's first phase has been scaled back due to rising costs.

Councillor Julie Cattell, lead member for major projects, said: “I’m excited to announce that we are issuing our invitation to tender for the restoration of Madeira Terraces phase one.

“Our vision is to restore the Terrace as a place for local people and visitors to walk, to sit and to enjoy views out to sea.

“To bring back its historic function as a venue for major events, but with new facilities to support pop-ups and events on the upper and lower decks.

“And to re-green the Green Wall, building on the healthy plants we can retain from the current planting.

“These works could form the blueprint for future renovation phases, demonstrating that the Terrace can be successfully restored within a budget.

“This first phase will see a significant investment of £11.6 million. We hope it will be a catalyst for securing further funding.”

The new lift will take over from the out-of-date smaller lift at Shelter Hall, which requires a person to be present to operate it. The lift, which requires major structural work, would cost £500,000 to repair and could form part of a future phase of the renovation project.

Repairs to the Royal Crescent steps will also not be part of phase one of the project but will remain open.

Suppliers are not invited to bid to carry out the highly specialist work, with contractors due to be appointed in spring.
