Three of the four chimneys at Battersea Power Station, an instantly recognisable part of the London skyline, could disappear - temporarily - as part of its redevelopment.
The landmark's Malaysian owners, who are carrying out an #8 billion redevelopment of the 39-acre site, have applied to alter the planning regulations covering the replacement of the crumbling chimneys.
Rules put in place by Wandsworth Council mean only one chimney at a time can currently be demolished and replaced, so as to deter developers from taking them down and not replacing them.
But Battersea Power Station Development Company has now asked for a "deed of variation".
This would allow them to demolish and partially rebuild one chimney as a show of good faith, before demolishing and rebuilding the other three simultaneously.
It argues this would cut the amount of time the #15 million replacement scheme will take by up to two years.A company spokesman said there was "no question" of the chimneys not being replaced."It is simply a case of speeding up the scheme," he said.
"If we do them one at a time it would take a lot longer. If we do one and then three it's a lot quicker.
The work to renovate the Art Deco 1930s power station is due to start later this year.The plans include 3,500 homes, 1.7 million square feet of office space, shops and a park.
