Petition to Sienna Real Estate Property Management Germany GmbH against the disfigurement of the former GSW Headquarters highrise

It was back in the 80's, at the point of the fall of the Berlin Wall, that I found myself in the company of LHMS in their newly renovated home in Notting Hill. You would know them better as Louisa Hutton & Matthias Sauerbruch, and we had the competition for the GSW HQ in Berlin on the boards amongst other things. It was some summer work after having been in their unit at the AA and the beginning of our architectural friendship that would lead me to Berlin. Please help my friends override this hasty decision from these eager developers by signing this petition. Many Thanks
