The Super Four Mast Spacenet, constructed for the 1987 Federal Horticultural Show in Düsseldorf, remains a prominent example of structural engineering applied to public infrastructure. As a specialist in tensile architecture, Conrad Roland transitioned from architectural theory and professional practice in Germany to the creation of large-scale rope-based climbing frames that redefined playground design.
Architectural Education and Early Practice
Born in Munich in 1934, Roland completed a carpenter apprenticeship before pursuing formal architectural training. His education spanned the Technical University of Munich, the Illinois Institute of Technology, and the TU Berlin. During a formative period between 1959 and 1961, he served as an assistant in the Chicago office of Mies van der Rohe. In 1963, he established an independent practice in Berlin, where he focused on documentation and conceptual studies regarding hanging houses and spatial networks.

Roland gained recognition for his analytical work on lightweight structures, supported by a scholarship from the Graham Foundation for Advanced Studies in the Fine Arts. His 1965 publication, Frei Otto – Spannweiten, provided a comprehensive study of spatial net architecture. Beyond his writing, he contributed to the field through international lectures in Canada, the United States, and Portsmouth throughout the late 1960s, while concurrently working on unbuilt projects such as an unrealized sports stadium in Abu Dhabi designed with Jörn-Peter Schmidt-Thomsen.
Development of Spacenet Technology
Beginning in 1970, Roland shifted his professional focus toward the development of play-based spatial nets. In 1974, he founded the firm Conrad Roland Spielbau to manufacture these rope structures. His technical expertise was formalized in a 1974 patent for spatial networks, which detailed potential applications beyond playgrounds, including exhibition pavilions, work scaffolds, and furniture. The corporation COROCORD Raumnetz GmbH, which succeeded his original company, continues to utilize his design principles.
Major Installations and Later Years
Roland’s work was frequently associated with the Federal Horticultural Show (BUGA) in Germany. His projects included the 1975 Super Two Mast Spacenet in Mannheim and the notably large Super Four Mast Spacenet in Düsseldorf’s Südpark. This latter structure underwent remedial maintenance in 2007 to ensure its continued utility. In 1987, Roland relocated to Hawaii, where he lived until his death in 2020.
