David Chipperfield Architects has outlined ideas for the redevelopment of the Elizabeth House site in London, England, during a public consultation.
Chelsfield and London & Regional Properties purchased the site with a plan to develop it into a new office tower.
The practice intends to develop a single raised block with public space, allowing for eventual pedestrian links through Waterloo Station.
The building may include a winter garden and retail spaces will be kept to a minimum or even excluded.
Chelsfield plans to seek planning consent by April 2011 and construction is expected to begin in 2012.
The redevelopment could be complete by 2015, according to london-se1.co.uk.
A previous plan by P&O to replace Elizabeth House with three towers was rejected by former UK Communities Secretary John Denham.
