»Only those who think beyond today can secure tomorrow.«

At Kehrbaum Architekten, every project has a common goal, a common vision. As part of a team of 20 architects with international experience, everyone fulfils their role as a function of their talents. They all agree on one thing: here, their work is not based on the competition, but on their own high standards to make this vision a reality. Together we want to lead our built environment into a more sustainable future.

Managing directors

Klaus Kehrbaum
Managing Director
Architect BDA and urban planner

Simply carrying out a project across all architectural disciplines is not enough for Klaus Kehrbaum. For him, every project needs an individual, sustainable vision. His whole passion is to develop this vision with his clients. His core precept is responding to the needs of the people for whom he builds. As a versatile, courageous and authentic freethinker, he is held in high esteem by clients and has held honorary posts for many years.

Ben Leiffheidt
Managing Director

Never losing sight of the big picture despite his passion for detail – with this dialectical approach to architecture, Ben Leiffheidt creates solutions by connecting the diverse needs of clients. He is convinced that architecture must take responsibility, as the quality of our surroundings influences the quality of our lives. To offer a sustainable architecture for people, cities and investors that unites everyone. That is his vision.
