plans have been unveiled to redevelop a historic section of berlin’s city centre, a 14-hectare site near the famous rote rathaus (red town hall). 3 prominent teams of architects have come up with ideas: kiefer/chipperfield/graft – britain’s david chipperfield, and the two german architectural teams graft and kiefer landschaftsarchitektur.

all 5 ideas of the team seek to leave the area undeveloped – with no buildings.

‘at the moment, we are only in the early stages of our considerations,’ said berlin’s building director, regula luescher. the reconstruction of the so-called ‘town hall forum’ will not begin until year 2017, whether one of the five ideas suggested will ever be realised is to be decided in the summer of 2011 when a design concept for the site is due to approved by the city government and when in 2012 an official architectural competition will be organized.

the rotes rathaus (red town hall) is located in the ‘mitte’ district on rathausstraße near alexanderplatz. it is the home to the governing mayor and the government (senate of berlin). the name of the landmark building dates from the facade design with red clinker bricks.
