Davies Alpine House
The arched shape of this greenhouse is both a new landmark and a welcoming gesture towards visitors to the Royal Botanic Gardens at Kew (a UNESCO heritage site). In the tradition of the innovative, high-tech glasshouses of Kew, this design provides a balanced, energy-efficient growing climate for Kew's collection of Alpine plants. The height of the two back-to-back arched structures ensures efficient thermal updraught to expel warm air at the top of the structure. A fan-shaped cloth provides protection from sunlight. Underground, air is conducted through a concrete labyrinth where it cools down before being reintroduced at the bottom of the greenhouse.
