Plans to scale back a 1,000 ft skyscraper planned on the site of the Battersea Power Station have been labelled a “diversion” by campaigners.

The skyscraper, nicknamed “the Dyson”, is the centre piece of developer Treasury Holdings’ £4billion scheme to revamp Sir Giles Gilbert Scott’s Grade II* listed masterpiece.

Rob Tincknell, managing director of Treasury, said it was reducing the tower’s height by 50 metres from 300 metres to 250 metres and its diameter by seven metres, from 32 metres to 25 metres when he presented the revised plan to Mayor of London Boris Johnson.

Mr Tincknell said: “We have taken on board the comments made to us and believe the new masterplan responds to every concern raised in the last six months.

“One of them was the height of the building, people felt it was just a bit too high. It popped up above a couple of buildings in Westminster but now it has no impact on four out of the five views in the London view management framework.”

But campaigner Keith Garner, of the Battersea Power Station Community Group, said the new plan made little difference to the impact of the scheme.

He said: “The 50 metres is neither here nor there. The building will be twice the size of the Millbank Tower and is still far too big. It is a diversion form the central project to fix the building and reopen it.”

As well as the new tower, Treasury’s plans include a new Tube station for Battersea - privately funded at a cost of about £400million.

The power station itself would be turned into a retail and hotel complex, complete with performance arena.

A ball room, primary school and medical centre would also be built.

The development would be home to 7,000 people and would create 13,000 new jobs - 2,500 during the construction phase.

Treasury hopes to submit an application to Wandsworth council in the summer.

If approved construction work would start in 2012 and the project would be completed in 2020.
