Sounds for the Future - Open House on 3 & 4 December

In 1966, four eager youngsters started a new challenge. Right from the start, the ambition of Jan Tanghe, Jacques Pêtre, Ignaas Deboutte and Willy Canfyn was to create an interdisciplinary group. ‘Groep Planning’ was born. A team of architects, urban planners and engineers worked together on numerous complex projects. By transcending the classic structure of a design agency, ‘Groep Planning’ developed a global vision about (urban) space. The interdisciplinary character was highlighted in 1995 with the integration of ‘Mens en Ruimte’. The team was extended with experts in the field of energy, environment, mobility, agri- and horticulture, sociology, economy, geography, planning, etc.


Today, 50 years later, the 3 partners, prof. Paul Lievevrouw, Jean-Pierre Mariën and Jan Jonas-Szatanski, are emphasizing again the SUM between SumProject and SumResearch. Sum stands for the continuous intertwining of the culture of projecting, scientific research and research by design. The interdisciplinary team is supported by cross-functions ensuring the sustainable dimension of the projects, an overall quality management, sound budget-making in an economic reality, an efficient project management and a clear communication strategy. SumProject+SumResearch is active in Flanders, Brussels, Wallonia and the northern part of France.

Sum is celebrating its 50th anniversary with ‘Sounds for the Future’ during an 'Open House' in our offices - boulevard de Waterloo 90 Waterloolaan Brussels. You can discover a selection of Recent Works exhibited in our offices during the weekend of 3 and 4 December from 10 am to 7 pm. It would be a pleasure to guide you through our work and visions.
