UK-based Proctor and Matthews Architects has submitted plans for a 34m-tall Heart of Africa Biodome at Chester Zoo, England.

The £90m ($143m) scheme is touted as biggest biodome and is sited on a 16,000m² area and is larger than the Grimshaw-designed Tropical House at the Eden Project in Cornwall.

The scheme is part of the £225m ($359m) ‘Natural Vision’ redevelopment proposal for the zoo, and is overseen by AECOM and Barton Willmore.

The EFTE-clad structure will feature an undulating, free-form roof structure. The interior is expected to simulate the natural African rainforest habitats of the Congo, with a jungle canopy and authentic climate.
