The noise and vibrations from a mechanical digger smashing through concrete “was enough to shut us down and absolutely stop any recording session dead”, said furious AIR Studios owner Paul Woolf.

As Mr Woolf spotted builders bring a large mechanical digger onto the site of the listed house in Rosslyn Hill on Monday morning, his lawyers Birkett LLP phoned the scheme’s architects and fired off a letter threatening an injunction to stop the work.

The letter said: “You are fully aware that undertaking exceptionally noisy work, which will also cause vibrations, will not simply interrupt the recording sessions but will no doubt cause them to be abandoned by the Studio users.

“We consider your decision to go ahead with these works in spite of the impact on our client’s business to be unreasonable behaviour on your part.”

The lawyers wrote: “For you to continue with works today in the knowledge that this will impact negatively upon our client’s business is unacceptable and unreasonable.

It continued: “Should you continue with the breaking works this afternoon, or at any time during which you are aware that our client’s business will be interrupted, we entirely reserve our client’s positions regarding a claim in damages against your clients for any losses caused as a result of the works.

“We further entirely reserve our client’s position regarding an application for an injunction either to stop the works or to have the Court impose a timetable upon you to ensure that our client’s business is not unreasonable interrupted.”

However in a post-script, the lawyers noted: “Since drafting this letter we have been informed that the breaking works have already begun.”

Mr Woolf said: “We had sound experts in the main hall recording the vibrations. It was enough to absolutely stop any session dead. Fortunately nobody was recording there at the time. This was just luck.”

More than 10,000 have signed a petition against the plans, which were submitted to Camden Council by Andrew and Elizabeth Jeffreys, for a basement swimming pool, gym, and cinema under their house.

Queen guitarist Brian May, head of the British Film Commission Adrian Wootton and Oscar-winning film composer Hans Zimmer have also thrown their weight behind the campaign.

With its unrivalled acoustics, AIR Studios, founded by Beatles producer George Martin in the Grade II-listed former church and missionary school Lyndhurst Hall, in Rosslyn Hill, has seen some of the world’s biggest movie scores and top musicians record there.

As reported in the Ham&High, Mr Wootton said that AIR, along with Abbey Road Studios, is one of only two recording studios in the UK to provide score recording services for major international feature films.

“If AIR Studios were unable to operate for an extended period, the UK’s draw for major international productions would be severely compromised, which in turn could have severe implications for the wider economy,” he said.

Queen guitarist Brian May previously said: “Given the outstanding contribution to the British Music and Film Industries which AIR Studios makes, it is almost unbelievable to me personally that Camden Council has not thrown out this developer’s application already.”

On behalf of Mr and Mrs Jeffreys, architect Thomas Croft said: “We advised the studio in advance of these archeological investigations and agreed times that noisy works could take place and we will continue to make every effort to avoid disturbance to the studio.”
