The architecture firm slapa oberholz pszczulny | sop architekten is developing offices and headquarters as well as projects for commercial, hotel, industrial, educational and residential purposes, including airports, sports stadia and research facilities. Based in Dusseldorf with 90 employees, the international firm is committed to a clear and timeless architectural language and offers every design brief, irrespective of the size of project or building type.

Our scope of work includes urban planning analysis, sophisticated planning preparation, design from concept to detailed development, project and construction management, coordination of all consultants, interior architecture, general contracting as well as the revitalisation of existing properties. Sustainably is key from the beginning of the design process, saving resources and improving the quality of life, proven with numerous certifications and awards.

In addition to the eponymous Jurek M. Slapa, Helmut Oberholz and Zbigniew Pszczulny, who have been working together for more than 30 years, Wolfgang Marcour and Lothar Simonis extend the executive shareholders with Bjørn Polzin as managing director. With buildings such as the Gap 15, the Hyatt Hotel in Media Harbour, the Stadium or the new Dusseldorf Airport, sop architekten heavily influenced the skyline of Dusseldorf. Further signature references are e.g. Wroclaw’s UEFA Euro football stadium, the Campustower apartment building at Hafencity Hamburg, the extension of the Messe Dusseldorf, the Orjin Maslak business centre in Istanbul and the Terminal 1 Extension at Munich Airport.


Every brief is a new challenge, irrespective of the size or nature of the project. We embark on each new project with enthusiasm and the goal of producing a bespoke solution for each client, bringing 30 years’ of design experience and a team of skilled and committed staff to the table. It is their ideas and expertise that form the foundation of our success and the strength of our firm.


Bringing a concept off the drawing board and making it a reality requires expert project management and oversight and the ability to manage a large number of different players. Every successful outcome is the product of fruitful collaboration between a wide range of partners. Whether you need a plant technician or a landscape architect, a lighting designer or environmental consultant, we have a strong network of external partners and specialists that we can call on whenever we need them.


Our architecture is timeless, clearly structured and made to last – we simply don’t believe in short-term flashy solutions that make an effect at any price. Every building should still be as relevant and appropriate, as coherent and “in its place” in 30 years’ time as it is today. Sustainable and energy-efficient construction are commitments that we take very seriously, out of conviction, not because “green building” is flavour of the month.
