Corscale has appointed McLaren Construction and Phoenix ME under a preconstruction services agreement to begin early works on a £253.9m data centre in Iver, Buckinghamshire.
The scheme will be built on a 14-acre site at Court Lane next to the M25.
It comprises two data centre buildings and a 140MVA substation.
Architect Gensler designed the project, which data intelligence provider Glenigan values at £253.9m.
McLaren Construction said in a statement that it will act as main contractor, supported by Phoenix ME as MEP delivery partner.
The wider project team includes Cundall on MEP design and L&P Group providing engineering support.
The design includes cladding and architectural features intended to sit alongside a nearby Grade II-listed Iver Court Farmhouse, while also incorporating biodiversity measures.
Julian Michalski, Corscale Europe head of development, said the project team had been selected to provide technical expertise and programme certainty ahead of a planned practical completion date in late 2029.
David McDonnell, managing director for data centres at McLaren Construction, described Iver as a “landmark scheme”.
He added: “As data centres become larger, more powerful and more complex, we become all the more reliant on the latest construction technology to achieve the project management and precision that this design requires.”
Predevelopment works, including site clearance and enabling works, are scheduled to begin on 1 July.
The site is currently occupied by an industrial estate.
Early activities will include the diversion of two 36-inch water mains by Affinity Water and delivery of a remediation strategy for the site.
The Iver data centre planning application had been called in by then-deputy prime minister Angela Rayner in July 2024 after Buckinghamshire Council rejected the proposal.
But it secured planning approval five months later.
In a December 2024 statement, the Ministry of Housing, Communities and Local Government said the site represented an optimal location for a data centre.
It added: “There is a clear lack of alternative sites available at present to meet the demand for such data centres in the Slough and Hayes availability zones.
“Failure to meet this need could have significant negative consequences for the UK digital economy.”
