Talking about Tectons . . .

This week’s VIP Tecton Tour highlighted the intensity of work our unique Modernist conservation project has demanded throughout the past 18 months.


While the work in itself has been consuming, visitor logistics were a challenge – we remained open to the public during the whole of the restoration programme which is no mean feat when two of the 1930s Tecton structures, Entrance and Safari Shop, were in constant use and both geographically placed at the point of entry and exit for all visitors.

“The transparency of the project allowed visitors to keep up to speed with reparation work and share our delight at uncovering treasures from the past – and our frustrations when inclement weather hindered progress.”

Rain didn’t stop Team Tecton thanks to a shrink-wrapped waterproof skin across the full span of the Bear Ravine.

DZG has the world’s largest single collection of Tecton structures, which were designed by renowned Modernist architect, Russian-born Berthold Lubetkin, and built during 1935 and the zoo’s opening in May 1937.

Jill said: “Today’s market offers a vast range of versatile building products, but in 1937 when DZG ?opened to the public the designs of the Tectons were considered structurally daring and made use of a new material, pre-stressed concrete.

She added:? “Across eight decades it would have been easy to allow them to decline into the role of concrete dinosaur instead we chose to offer them sanctuary, gradually adapting them as a modern zoo evolved.
