More than 20 years ago I designed the pyramid-house „Pi“ on the occasion of a fair for housebuilding I drafted and organized by order of noted builders. The press refered this dream house as „livable artwork“ – already then I refered it as pi-ramid – cause the plans actually met demands of individualists being versed in technology. Yeah – always I was faszinated by the pyramid´s form and its attraction. Now – after 2 decades – when I dare to design irrational and transcendent numbers – without any thought of the pyramid – I´m really astonished to touch down on the old topic by the act of creation.
