Plans to build another three data centres on Green Belt land between Buckinghamshire and Slough have been put forward.

The new technology hub would be located at Thorney Business Park off Thorney Lane just outside Iver.

The data centres would measure a total of 90,000 metres square and be up to 25m tall, according to Thorney Lane LLP’s application for a screening opinion from Buckinghamshire Council.

The applicant said: “Each data centre is expected to have a dedicated car park on the eastern side, where the buildings will be accessed from.”

Access to the site will be from the southeast via a new roundabout junction with Thorney Lane, with a second roundabout proposed.

Each of the three data centres are expected to be aligned horizontally, with office facilities in the eastern end of each building and backup diesel generator gantries located on the western end of each building

The 18.6-hectare development site is a rectangular piece of land located approximately 5km east of Slough, near to the edge of the M25 motorway.

It is bound to the north by the Grand Union Canal, to the west by the remaining area of the Thorney Lane business park, to the east by Thorney Lane North and to the south by the mainline railway.

The site is currently partly used as a business park, with most of it being classified as Green Belt land, apart from the northwestern corner.

However, it was historically used for gravel extraction until the 1960s, when it was filled with construction and demolition waste before partly being developed for industrial use.

The three data centres proposed by Thorney Lane LLP at the site are in addition to three other data centres proposed by Segro that already have planning consent in the western portion of Thorney Lane Business Park.

Plans for Segro’s three data centres include offices, plant, equipment and emergency back-up generators and associated fuel storage, landscaping, sustainable drainage systems, parking, a new vehicular access from Thorney Lane South and a new emergency access route to Hollow Hill Lane.

On top of these six data centres, another application for permission to build a new data centre nearby has just been submitted to the council by Cyrus One.

The company has re-field its plans to construct the facility on the other side of the M25 up at Iver Heath.

A data centre is a physical location housing computer equipment and servers to store, process and transfer large amounts of data.
