The small open enclosure south east of the Elephant and Rhino Pavilion was built in 1922 as a racoon enclosure and used for red pandas before passing to mongooses. It consists of a grassy mound within a reinforced concrete octagonal retaining wall. This wall has an inwardly splayed upper lip to prevent escape. An ailanthus tree at the centre of the mound was uprooted in the destructive storm of October 1987.
Demolished and area used for the new Children's Zoo in 1995.
The New Lion Terraces displaced Anthony Salvin Junior's Lion House of 1875-77 and the Cattle Sheds of 1869 which, from 1967, had included Chi-Chi's Giant Panda Enclosure. It came in the 150th anniversary year of the foundation of the Zoological Society of London and was the final component of the post-war reconstruction programme. The terraces are a rambling complex covering two acres of largely open space. The buildings are deliberately obscured in favour of landscaping that was intended as an improvement in the display and welfare of the animals, an approach that relied on the precedent of the lion and tiger exhibits at Whipsnade. It was built 1972-76, funding from Government and Sir Charles Clore; brief by D M R Brambell, Curator of Mammals; John Toovey, Colin Wears and Roger Balkwill, architects; Margaret Maxwell, landscape architect; R T James and partners, engineers; J Jarvis and Sons Limited, building contractors. It cost £666,232. Sculpture enrichments include a finely lettered slate dedicatory plaque designed by Banks and Miles and cut by David Kindersley. Another stone inscribed 'The Lions House' was taken from above the entrance of the 1875-77 Lion House (the 'S' is a 1970's insertion). A large lion mask was similarly resited and there is a cast lion's head presented by its sculptor, William Timyn, in 1976.
The group of buildings that forms the Bird Incubation and Rearing Centre was formerly the Zoo's North Gate. It has three sections: the former North Gate itself, flanked by a former toilet block and the former North Gate Kiosk. Built 1926, probably by Walter, Hearn and Chuter, architects. North Gate Kiosk added 1936, Tecton (Berthold Lubetkin), architects. Closed and altered for use as a store, 1975. Converted 1989-90, Colin Wears with the John S Bonnington Parternship, architects. North Gate Kiosk listed Grade II. The North Gate Kiosk, added on the east side of the North Gate, was based on Lubetkin's 1934 Shelter and Kiosk for Whipsnade and was paralleled by his Main Entrance at Dudley Zoo of 1936-37. The kiosk included a gatekeeper's lodge to the west, roofed as part of the North Gate and, beyond a passage to the exit turnstiles, a block for a cloakroom and refreshment bar.
