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 Konyalıoğlu, complement our management team.
