It’s a century since the birth of Frei Otto (1925-2015), the German structural engineer and architect and one of the pioneers of the new, lightweight style of highly technical architecture that was to dominate public buildings, event spaces, spans and stadiums from the 1970s onwards.

Who is architect and engineer Frei Otto?
Frei Otto: Building with Nature looks back at Otto’s life and career, with special emphasis on the designer’s exploration of large-scale, lightweight structures. These days, Otto’s legacy is pretty much cemented by the dramatic landscape of the Munich Olympic Park, started in 1968 and completed for the 1972 Games. The tented structures, some of which ring the tiered seating of the Olympiastadion, co-designed with Günther Behnisch, were inspired by Alpine vistas.

Behnisch had been switched on to Otto’s work by the dramatic forms of the West German Pavilion at Expo 67 in Montreal. Characterised by his intense study of plant structures and geometry, Otto’s biomechanical forms predated the digital age and the widespread use of CAD design. Instead, the method of choice was model making, and the book is awash with imagery of these detailed, structurally precise, scale models that helped Otto determine how materials would perform.

In Otto’s view, lightweight architecture meant minimising a structure’s impact on the environment, not just physically but also in terms of use of materials and energy. It was the heyday of high tech’s association with what were once left-field concerns but are now mainstream architectural thought. Awarded the Pritzker Prize in the week of his death, Otto’s contribution to the sustainability debate can’t be overstated.

Projects include Montreal and Munich, as well as Otto’s own house and Atelier near Stuttgart (completed in 1971), the Multihalle exhibition centre in Mannheim (1975) and many more, along with unbuilt projects and schemes.
