The building: The great Glasshouse Hans painted after visiting botanical garden in Wales where architect Norman Foster (known for high-tech buildings with sustainable label) built the world's largest single-span conservatory.
It is a greenhouse with plant species from several continents and provides a model for sustainable development.
The greenhouse's location in the rolling hills overlooking valley impressed because its ingenious construction, an ellipse in glass reflecting the undulating landscape, merges with its surroundings : a perfect symbiosis of nature and culture!
