Opening by Queen Elizabeth

In addition to the projects for clients such as Keukenhof, Floriade 2002 and botanical gardens in Leiden and Frankfurt, Smiemans completed a prestigious project at Wisley Garden near London: for the internationally renowned British Royal Horticultural Society (RHS). This project required a special educational glasshouse, which is now known as "The Glasshouse" and attracts more than 1 million visitors every year. Smiemans built the entire structure and installed and commissioned all climate, mechanical and electrical services. Queen Elizabeth officially opened The Glasshouse in celebration of the garden's bicentennial year on June 26, 2007.

Thee Botanical Climate zones

The HighLight system has been used here in a unique design: the maximum heights are more than 12.50m and the total surface is more than 7,000 m². The typical rounded shapes give the glasshouse its magnificent classic-contemporary look. Everyone can enjoy, see, smell and feel the tropical and subtropical flowers and plants in “The Glasshouse”. Its setting is spectacular with a waterfall, rock formations, caves and a wealth of plants and trees. There are three climatic zones, a moist, a dry and a tropical climate (high temperature and high humidity). In the tropical zone the RHS organizes an annual butterfly show, which is very impressive as shown by the many visitors. The Glasshouse transforms into a tropical paradise with more than 6,000 free-flying exotic butterflies.

The Clore Learning Centre

The RHS experts in Wisley are very pleased with the prosperous growing and blossoming of all their exotic plants, partly because of the excellent lighting and climate conditions. In addition to this showcase we also built nursery greenhouses, technical areas and classrooms using the more traditional Venlo glasshouse system. The Clore Learning Centre, incorporating a Discovery Room and a Growing Lab for practical gardening and science creates a flexible learning space with more than 5,000 cultivated plants in three different temperature zones and the interactive Root Zone.
