bauraum defines his way of working architecture by the sum of two components:
creating spaces and envelopes

  • « bauraum Model » offers to its clients architects, engineers, landscape designers, building owners, companies, designers and artists architectural, design, art and prototype models.
  • « bauraum Facades » provides consulting in envelope engineering for the same customers.

bauraum welcomes you at 1, passage Hennel, in the XIIth arrondissement in Paris.

Created in 2012, the workshop is led by two partners Claudia Dieling and Axel Steinmüller.


Within our professional practice, we respect a certain number of ethics’ rules decided for the common good.

  • Respect and obligation for mutual confidentiality are at the basis of our client relations
  • Often intervening in the competition phase and having in the context of our missions an access to internal and external resources of our clients, we are bound by professional secrecy. We do not divulge under any pretext the least information that could injure the activity, image, reputation or competitive position of the company or institution that resorts to our services.
  • bauraum is committed to reduce as much as possible the use of toxic products for human health or the environment.
  • The design of façades is carried out with the permanent concern for sustainability and high environmental performance. We commit to respond to environmental current norms and defend a vision and responsible attitude toward our environment.
  • bauraum guaranties the conformity of its performances with current legislation as well as with fundamental and universal principles of human rights.

Claudia Dieling, co-founder and partner of bauraum is an experienced architect and engineer. She is a graduate of the RWTH University of Aachen in Germany. Claudia started her career at MGM Arquitectos in Sevilla, then worked at Minkus + Wolf Architekten in Cologne before she joined the Dominique Perrault office in Paris. Four years later, in 2006, after a stint at Brunet Saunier Architecture, Claudia went to work for RFR Ingénieurs.

Having always been passionate about the quest for detail and its constructive aspect, she has a rare know-how in the sector of glass and opaque envelopes, skylights and canopies as well as the renovation of façades and innovative materials.
