The exhibit will feature a new paddock surrounded by a moat, night quarters and a day gym for the gorillas, as well as visitor viewing verandas and a walkthrough aviary.
Two of the Regents Park zoo's existing Sobell pavilions and a covered walkway will have to be flattened to make way for the new development.
Though none of these buildings are listed, because the zoo is in a conservation area the practice has also submitted a conservation area consent application for this demolition work.
The scheme will be the third project the practice has designed for the Zoological Society of London.
Others include the lion enclosure at Whipsnade Animal Park, in Bedfordshire (featured in the AJ 01.09.05) and the new walkthrough squirrel monkey exhibit at London Zoo.
Over the years the zoo has landed a number of top architects to design exhibits and enclosures. Perhaps the most famous is Lubetkin's Grade I-listed penguin pool, which currently stands empty.
