Foster and Partners is to present its tall office-block design for the insurer Swiss Re to the Royal Fine Art Commission this morning (Thursday). The design for more than 1500 staff will stand on the site originally proposed for Foster's London Millennium Tower. However this design is said to be smaller than the nearby Tower 42, the former Nat West Tower, which is - unsurprisingly - 42 storeys high. A planning application was due late last night or today. The site is the former Baltic Exchange, bombed by the ira in 1992.
