BLOCK F: HIGH-END FACADE ELEMENTS This formulation certainly has a double meaning: it relates to the high technical demands and the fact that the residential tower is approximately 140 metres high. With its 35 floors and its distinctive sculptural architecture, it is a firm landmark of West London. The building shell comprises about 2,400 prefabricated facade elements cladded with glass, ceramics or a combination of these two materials. The elements were realised by a successful interplay of competencies exhibited by the two renowned specialists Lindner Fassaden GmbH, D-Arnstorf (in co-operation with its local partner Lindner Facades, London) and Agrob Buchtal GmbH, D-Schwarzenfeld (in co-operation with its local partner EH Smith, GB-Solihull and GB-Brasted). All elements were manufactured by Lindner Fassaden GmbH in Arnstorf in Lower Bavaria. Before that, the elements and composite system were inspected in detail in terms of the requisite properties such as sealing against air and water or noise protection. The standardised versions were then manufactured within the framework of sophisticated line production while special versions such as wing or corner elements were manufactured in a so-called island production process. In optimising the material flow, the distinctive experience offered by the company in areas of lean production and the Kanban system paid off in practice. DETAILS ON THE CERAMIC CLADDING (PART OF AGROB BUCHTAL) The architects PLP Architecture, London, desired a salmon-coloured terracotta shade in three differentiated nuances and two surface finishes (smooth and grooved) for the ceramic-clad elements. DETAILS ON THE ELEMENTS (PART OF LINDNER FASSADEN GMBH) The warm facade largely comprises elements which are 1.5 metres wide and 3.25 metres high, whereby the Lindner CW85 system permitted a certain level of standardisation and therefore improved feasibility. At the same time, the building’s distinctive silhouette also demanded individual special solutions. One example is represented by the staggered eastern side where every second floor forms a step offering patios for its residents. Furthermore steel balconies were created elsewhere. This required the use of thermally separated “wing elements” 2.25 metres wide which not only clad the cold area but also serve as wind and visual protection. The southwest side is marked by another typical feature in the form of an elevator shaft which is visible from afar and where all-glass elements measuring 3.05 by 3.25 metres ensure optimum transparency.
