Plans for what would be “one of the tallest schools in the world” have been quashed by the government following a planning row last year.

London South East Academies Trust (LSEAT) proposed a gigantic 10-storey academy with no play area or on-site parking at land on the corner of Westmoreland Road and Masons Hill in Bromley.

The trust appealed Bromley Council’s rejection of the Science Health and Wellbeing Futures Academy, taking the row to a planning inquiry in November.

The trust proposed a school looming 119ft over gardens of nearby homes – making it the tallest school in Britain, and “probably one of the tallest in the world”.

The school would have towered to just under height of the great pyramid at Giza and the Washington Monument.

Campaigners – and some local councillors – said a high-rise school with no outdoor play space would be unpopular with parents.

The trust said the pressing need for school places outweighed adverse effects that the new school would have on the area.

Planning inspector Brendan Lyons has dismissed the trust’s appeal – rejecting the scheme for a second time.

“I have concluded that the proposal would have significant adverse impacts on the character and appearance of the area and on neighbours’ living conditions.”

The council argued the school was unsuitable because of its character, impact on residents and concerns over highway safety.

More than 200 people objected to the original proposals and neighbours and campaigners turned out during November’s inquiry to argue against the high-rise school.

The school would have enough spaces for 1,260 pupils, and be spread over a part-four and part-10-storey building standing at 119ft.

Councillor Alexa Michael, chairman of the council’s development control committee, said: “The appeal outcome has vindicated the DCC’s decision that the site would have been unsuitable for a six-form-entry school in terms of the height, bulk and massing proposed and the impact on neighbouring properties.

“If allowed, the school would have been the tallest in Britain and the third highest in the world. Fortunately, commonsense has prevailed in this case.”

The site has been earmarked to be used for educational purposes, and the council said it does not object to a school being built there – it does however take issue with the proposed design.

Bromley Town councillor Nicola Dykes said she was delighted residents’ concerns had been heard.

Cllr Dykes, who spoke at the inquiry, said: “Whilst school places are important it should not come at the expense of neighbouring residents whose amenity would have been ruined by this 10-storey building.”

A spokesman for London & South East Education Group, which LSEAT is part of, said: “There is no disputing the need for more school places in Bromley, but we fully respect the planning inspectorate’s decision that a more suitable site needs to be found.

“We will continue to work with EFSA and the local authority to help address the growing demand for school places – with our aim to create additional high-quality secondary provision for young people in the borough.”
