• Profile

For over 30 years, architects J.M. Slapa, H. Oberholz and Z. Pszczulny have been developing and realising joint projects for administrative, commercial, industrial and residential purposes, including airports and sports stadiums. Based in Düsseldorf with some 90 employees, the international architecture firm of sop architekten is committed to a clear and timeless architectural language as well as a holistic approach to their constructions, down to the last detail. This includes urban planning analyses as well as the revitalisation of existing properties, professional execution planning and construction management, sophisticated interior design or taking the lead in sustainable construction.
With buildings such as the Gap 15, the Hyatt Hotel in Media Harbour, the Esprit Arena or the new Dusseldorf Airport, sop architekten have heavily influenced the face of Dusseldorf. The Orjin Maslak business centre in Istanbul and Wroclaw’s UEFA Euro 2012 football stadium are two of the firm’s successful international endeavours.


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 25 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.
