is likely to be needed for planned work on a 140-metre cylindrical tower at Paddington Basin.
Westminster Council approved plans for the work on the building, which has already been nicknamed the Cucumber.
Billionaire brothers Simon and David Reuben are behind the 42-storey skyscraper which will include 222 flats, a boutique hotel and a roof-top sky bar.
The developers will need to ensure the security of the site as it works on the multi-million pound project.
Having received planning permission, the developer can now work on more detailed aspects of the site which will be put before the council for consideration later in the year.
Planning committee chairman councillor Alastair Moss said: "We have given our approval to certain key aspects of these detailed plans including the height and design of the buildings and the public realm between them.
"The architectural designs are impressive. They could deliver an iconic addition to London’s skyline and serve as a focal point for Paddington and the surrounding area."
Building firms were recently advised by the Health and Safety Executive that security fencing
is important on construction sites.
