A decision over whether a massive data centre can be built on the edge of a Wiltshire village has been put off until the new year – to the fury of the company behind the project.
Rob Silvester , chief revenue at Corsham-headquartered Ark Data Centres said Wiltshire Council’s decision – with just 24 hours’ notice – to delay determination on whether a 60ft tall data centre could be built at its Spring Park Campus was “shocking.”
His firm wants to built the data centre on an 18-acre site known locally as the Donkey Field, near the villages of Westwells and Neston and close to Wadswick Green retirement village.
The proposed building will be 18.7 metres (61 feet) tall at its highest point and approximately 180 metres, or nearly 600 ft, long.
At its closest point, the proposed development would be 44 metres (144 ft) from the nearest house.
Ark says the data centre will help meet soaring demand for data storage, related in a large part to the public’s adoption of AI, cloud storage, and streaming services.
Its clients include businesses including telecoms firms, banks, and video streaming services, and the government.
“I’ve been a chartered surveyor for 35 years been working in development for that period of time and have never seen anything like this,” Mr Silvester told the council’s strategic planning committee yesterday (Tuesday, December 16).
“After 18 months of thorough interrogation by highly qualified planning engineering and technical experts officers, recommended our application was approved.
“Data centres play a crucial role in all of our lives. None of us could operate without data centres. It’s critical national infrastructure. It’s really, really important.”
He said the development of the firm’s seventh data centre at the Spring Park Campus – the former MOD Corsham – represented £300 million of a total £1 billion investment on the site.
And he warned: “As a local business, we’re committed to investing in our own county when, frankly, we can make investments elsewhere.
“We are trying to continue to invest in Corsham. This is a strategic investment. It’s a large investment. We have sites
in London, Brussels, Barcelona. We have a decision to make.”
Wiltshire Council departments including highways, rights of way, conservation, archaeology, public protection, landscape, ecology and drainage offer no objections ahead of the meeting.
But over the weekend a 17-page rebuttal of the 55-page planning officers’ report was submitted by Neston Westwells Action Group – an affiliation of locals opposed to the plan – was submitted.
The officer’s report, the meeting heard, was not made public until a week before the meeting – leaving NWAG little time to formulate their response.
The response prompted a rethink from flooding experts at the council, who had originally said they had no concerns over flood risks posed by the development.
Council lawyers said that without considering the action group’s response, there was a risk of any decision being taken to court.
“I can’t in all good conscience at this stage advise the committee that they have all the information that they need in order to make a proper decision,” the council’s in-house lawyer told the meeting
“Any decision that you made today to either grant or refuse permission would be vulnerable to judicial review, and that is not in your interest and it is not in the applicant’s interest.”
Proposing to defer the matter until the January or at the very latest February meeting of the strategic planning committee, chairman Ernie Clark said: “It’s both disappointing and very unusual, but some of the matters that were raised would be substantial enough that, if this was approved today, we would get taken off to judicial review.
But he warned those opposing the scheme: “Please don’t think that it will be deferred again, because it won’t be. When it comes back there will be a decision made.”
