Rainforest is a public pavilion by Chilean-German architecture practice GUN Architects, installed in London's Bedford Square during the Summer of 2014. An imposing five metre high micro-climate of minimal tree-like structures with a field of pyramidal fabric ‘stalactites’ which gently drip water – the pavilion is an oasis in the centre of London. Visitors can sit beneath a canopy of inverted prisms to enjoy a forest-like environment of raindrops, pools and plants.

Rainforest is part of GUN Architects' exploration into natural dynamics in the diverse Chilean climate – making water a protagonist of the architecture, where the production of temporal atmospheres is based on water circulation and accumulation. The practice engages in architectural and urban projects rooted in the environmental and cultural context of Chile, attempting to develop design forms which are consistent with current urban expansion and its associated geographical conditions.

An exhibition in the main AA Gallery accompanies the pavilion and describes the development of Rainforest through earlier research by GUN Architects, the pavilion’s conceptual evolution and technical engineering. The exhibition also features photographic works by Cristóbal Palma and Helene Binet.

The installation is part of the London Festival of Architecture 2014 – an annual event that "celebrates the City’s role as a global hub of architectural experimentation, thinking, learning and practice." The festival takes place between the 1st and 30th of June.
