A crystal made of glass and concrete
Like a huge crystal, in London's historic centre - the nine-storey office building at One Coleman Street impresses with its unique vitreous facade. Each of the solar control glass panes is tilted at a different angle, in which the structural glazing was glued to the frame construction without any visible fasteners. None of the "prefab" steel parts were used more than six times. In spite of all these variations, the geometric shapes provide for an overall spatial symmetry. The building, however, also meets the highest technical demands: 3,000 square metres of solar control glazing (ipasol neutral 68/37) allow a lot of daylight into the building, in turn preventing the rooms from heating up too much in the summer and also providing effective thermal insulation on cold days.
