A 90-metre tower has been proposed for the site of Hampton House on Albert Embankment.
The current office building would be replaced by three buildings designed by Foster & Partners providing 240 homes and a 167-studio apart-hotel.
The tallest building in the cluster would be almost 90 metres high (27 storeys). The other buildings would be 81 metres and 45 metres high.
The tallest part of this scheme would be taller than the London Television Centre tower on the South Bank (85 metres) but not as tall as Millbank Tower across the river (119 metres).
Owned by Newlands Enterprises, Hampton House is currently occupied to a number of tenants including the London Fire and Emergency Planning Authority (which is moving to Union Street), the Suzy Lamplugh Trust. There is a branch of HSBC at ground level.
A planning application is expected within the next month.
