Kurzbeschreibung
This jewel is in London Mayfair in the inner courtyard of 46 Berkeley Square and is an extraordinary piece of architecturally exposed steel construction.
The inner courtyard is used as a restaurant area for the luxurious private club “Annabel’s” and was designed by Palmer Lunn Architects.
The roof engineered by Waagner Biro steel and glass consists of seven segments, each consisting of two stainless steel arches and three curved glass units. Each roof segment is mounted on its own rails on which it can move freely. Due to a precisely fitting size difference between the individual segments, they can be telescoped into each other.
The opening mechanism is controlled via a control panel and can
This jewel is in London Mayfair in the inner courtyard of 46 Berkeley Square and is an extraordinary piece of architecturally exposed steel construction.
The inner courtyard is used as a restaurant area for the luxurious private club “Annabel’s” and was designed by Palmer Lunn Architects.
The roof engineered by Waagner Biro steel and glass consists of seven segments, each consisting of two stainless steel arches and three curved glass units. Each roof segment is mounted on its own rails on which it can move freely. Due to a precisely fitting size difference between the individual segments, they can be telescoped into each other.
The opening mechanism is controlled via a control panel and can be opened within 4 minutes to allow guests to dine in the open air. However, it not only offers protection in bad weather, but also acts as an acoustic barrier to prevent possible noise pollution during the night.
A major challenge was combining the tolerances for curved glass with the tolerances for the steel arches. It had to be ensured that the shapes of both materials matched 100%. This was achieved by reducing the allowable tolerances of the steel arches to half the values of the best class of BS EN ISO 13920.
