The history of asp Architekten goes back to the fifties. In this tradition we are committed to the highest architectural standards and integrity towards our clients. Today’s office is the direct legal successor of’asp’ Arat, Siegel und Partner, which was founded in 1992 by Mete Arat and Henner Siegel. During this time, large parts of the landside infrastructure of Stuttgart Airport, the Arena Leipzig and the conversion of the Stuttgart Neckar Stadium for the 1993 World Championships in Athletics (in cooperation with Schlaich, Bergermann and Partner) were built, which is now regarded as the prototype of the membrane construction for stadiums.

The office looks back on a long planning tradition with both its precursor firm, Siegel-Wonneberg & Partner, and the planning group of Mete Arat (Arat-Haisch-Volz). This is how the iconic buildings of the Rexroth foundry in Lohr am Main (Fig.) originated within the office of Curt Siegel in the early 1960s and the Museum of Natural History at the Stuttgart Loewentor in 1981. The German Library in Frankfurt am Main was the work of Mete Arat (1983-1997, with Dieter and Gisela Kaiser).

In 2006 Cem Arat, Karsten Schust and Jochen Siegel took over the sole management of the office and increased the number of employees to approx. 35-40 architects. Milestones include the conversion of the Mercedes-Benz Arena, the two EWE arenas in Oldenburg and the young talent centre of VfB Stuttgart.

UMnet urban matters After many years of cooperation, the integration of Markus Weismann and UMnet urban matters in 2015 also turned urban planning into another focus of the work of ‘asp’. The starting point of urban matters UMnet was the collaboration among prof. Alex Wall, Markus Weismann and Oliver Lambrecht at the Chair for Urban Construction and Designs at the University of Karlsruhe (KIT). After a series of competition successes, they founded their office in Stuttgart in 2008.

From the understanding of architecture as a holistic process, projects of all scales – from the city quarter to the interior – can now be developed from a single source.

Continuity As part of the recent restructuring, three of our longstanding project managers have joined the management team to ensure the continuity of the office and to be ready for future challenges. We are pleased that three outstanding architects and extraordinary personalities, Eberhard Becker, Dimitrios Kogios and Suna Konyal─▒o─člu, complement our management team.

With the end of the last decade an era of asp comes to an end: after 30 years of belonging to asp and after 14 years of office partnership with Cem Arat Karsten Schust withdrawed from the asp Architekten GmbH as partner and managing director on 31.12.2019. This generation change we planned with foresight to ensure as much continuity as possible.
The previous managing directors Eberhard Becker, Suna Konyal─▒o─člu und Dimitrios Kogios were appointed as partners. As of now, we are five managing partners together with Markus Weismann and Cem Arat to cover the full range of our projects.
