Genuinely Lab-esque, practically a sister building. Arup and Lubetkin's forerunner to our favourite art deco cafe.
From designmuseum.org :-
"Less than a year after his arrival in London, Lubetkin joined forces with a group of young architects to form a group named Tecton. Lubetkin’s command of English was still slight, but his young collaborators were awed by his intellect and sophistication. They opened a tiny attic office and struggled to find commissions, while the Trad v. Rad debate divided British architecture, and Lubetkin made his name by writing articles and giving speeches as a rad.
The first Tecton commission was a Gorilla House at London Zoo in Regent’s Park. He built the house in his favourite form, a circle, as a Corbusian machine à habiter for animals. Determined to build the circule in concrete, Lubetkin contacted the Parisian civil engineers, Christiani & Nielson, who referred him to their London representative, a brilliant young Dane, Ove Arup. Sharing Lubetkin’s zest for experimentation, Arup made an inspired contribution to the Gorilla House and they began a lifelong collaboration."
