Developers Gamuda Berhad and Castleforge have formally appointed Multiplex to deliver the £250m main construction contract for the redevelopment of 75 London Wall in the City of London.

The contract was signed this week, clearing the way for full construction to begin on the landmark scheme following extensive enabling and demolition works carried out by the Erith Group. The wider redevelopment carries an overall project value of £1.2bn, with practical completion targeted for the first quarter of 2028.

Multiplex has been closely involved in the scheme for the past year under a pre-construction services agreement, working alongside the development team to refine buildability, programme and sustainability strategies ahead of the main works commencing.

Once complete, the redevelopment of 75 London Wall will deliver more than 450,000 sq ft of Grade A office accommodation, repositioning an existing large-scale building into a future-ready commercial asset at a time when availability of high-quality office space in the City remains constrained.

Niall Farmer, head of Gamuda Land UK at Gamuda Berhad, said the contract award marked an important step in the group’s expansion in the UK market and its strategy to unlock long-term value from prime London assets. He added that the scheme represents a rare opportunity to transform a building of scale into highly sustainable workspace at a point when demand for top-tier offices continues to outstrip supply.

Michael Kovacs, founding partner of Castleforge, said the timing of the project was critical. With office construction starts in London at their lowest level in almost two decades, he said bringing the scheme to completion in 2028 would help address acute supply shortages, noting that successful office investment often requires building through the quieter parts of the cycle.

Callum Tuckett, managing director of Multiplex, said delivering a project of this scale in the heart of the City demands both technical expertise and innovation. He added that the scheme would set a new benchmark for sustainable commercial development, with the contractor’s early involvement enabling the project team to move swiftly into the delivery phase.

The redevelopment is expected to play a significant role in shaping the next generation of City office space.
