Profile

Fig. 01Behrouz Zafar, Hamburg

“Good planning is precise, honest and traceable — from the first line to the final account.”

With over 30 years of professional experience in Iran and Germany, I combine classical architecture and planning experience with today’s digital working methods. From 1993 to 2010 I ran my own architecture practice in Tehran – with projects ranging from residential construction to major infrastructure projects such as the Tehran metro.

In parallel, I founded an IT company and supported architecture and construction firms with hardware and software as well as my own online portal. The connection between planning and digital tools has therefore accompanied a significant part of my professional path. Since 2011 I have lived and worked in Hamburg and have continuously developed my experience in digital planning – particularly in CAD, BIM and cost estimation.
