A company has filed to develop a new data center campus outside London in Hertfordshire, UK.

Greystoke Land Ltd has filed with Three Rivers District Council for the demolition of existing buildings on a 33-hectare site north of Mansion House Farm along Bedmond Road in Abbots Langley to build a data center campus.

The company wants to build two data center buildings spanning up to 84,000 sqm (904,170 sq ft) along with ancillary offices, internal plant and equipment, emergency backup generators and associated fuel storage. The site would have an IT load of 96MW.

Other planned works include a 300 sqm "innovation, education, and training center."

Though close to the M25 motorway, the site is currently greenfield land located wholly within the Metropolitan Green Belt. While industrial developments generally aren’t allowed in the Green Belt, the company is aiming to develop a 21-hectare country park on part of the site.

Greystroke is a UK investment company specializing in land-use planning. The company says it works with landowners, developers, and institutions to finance and secure planning permission. Its projects include the planned Cherwell Logistics Park.

The end customer for this campus isn’t currently clear but is likely one of the hyperscale cloud providers. NTT operates several data centers in Hemel Hempstead, and Amazon has a presence in the area in a Prologis industrial park.

A report included in the filings references the site’s important proximity to an "existing hyperscale entity at Hemel Hempstead" to which this site would be partnered. It also suggests the Hemel Hempstead availability zone needs 500MW of capacity.
