Under new helm

In 2006 the paths of Michael Radtke and Stephanie Kloft crossed. A freelance job at MAR turned into a business partnership. By 2015, Stephanie joined the management and in 2020 she assumed control as sole proprietor.

Stephanie Kloft

Stephanie Kloft was born in Düsseldorf in 1970, and still living there. She is married and has 2 daughters.

After graduating from high school, she began studying architecture at the Cologne University of Applied Sciences, which she completed in Düsseldorf with 2 degrees. In 2005 she completed her studies as Dipl.-Ing. (FH) interior designer at the Düsseldorf University of Applied Sciences and in 2006 she studied architecture at the PBSA Peter Behrens School of Architecture with the title Dipl.-Ing. (FH) Architect.

During her studies, Stephanie trained as a carpenter in a Düsseldorf carpentry shop, where she learned the traditional trade.

Under new helm

Stephanie has been the sole proprietor of the office since 2020. In 2023, MAR will move to the new location in the urban area of Düsseldorf Pempelfort, among other creative trades, a stone's throw from the Rhine.

How it started

MAR Architects, founded in 1991 by Michael A Radtke in Düsseldorf, has been managed by Stephanie Kloft since Michael's retirement in 2015. Approximately 700 projects have been implemented in over 40 countries for more than 70 customers.
The result is a broad portfolio of knowledge and experience with World Expos, trade fairs and interior design around the globe guaranteeing the standards of "made in Germany".

How it started

Michael A. Radtke

Born in southern Germany in 1950, he moved to Tanzania with his family in 1963 because his father, a doctor, was leading the development of a public health care system around Lake Victoria. He completed his secondary education in pan-African schools in Mwanza/Tanzania and Nairobi/Kenya.

After studying architecture at the University of Stuttgart, in 1979 he started working for Lippsmeier + Partner (L+P), which specializes in tropical architecture and international exhibitions. From 1980, he was in charge of a large school construction project for German development aid in Dodoma / Tanzania for L+P and subsequently set up the L+P office in Dar es Salaam / Tanzania with 10 local employees. After his return in 1988 he became manager of the L+P office in Düsseldorf.

The MAR Architects office, which started in Düsseldorf in 1991, developed over the course of project development and contacts into a multilateral concept, design, planning and management tool that successfully implemented trade fair, exhibition and interior design projects worldwide with clients from the public and private sector.
