building envelope.
The facade has been carefully designed to respond to the site conditions. The southern window fronts are shaded by the terraces in front, and are fitted with glass railings across the whole facade. These windows can be fully closed by sliding and rotating all-glass elements. As a result, the terraces act as a buffer against the wind on all floors, providing optimal climate control for the apartments.
All rooms on the south, east, and west facades are equipped with highly reflective interior solar shading. The surrounding wave elements offer sun, wind, and noise protection. Every component of the facade, from the aluminium shafts to other elements, was carefully affixed to the structure,

like the facade construction itself, with “high precision.” This was helped by the application of the same universal steel brackets throughout. “This innovative approach not only ensured a high level of accuracy but also simplified both the planning and assembly processes,” say the architects. To achieve the desired aesthetic impact of the metal exterior, similarly precise design techniques were employed. The rotating shaft elements were generated “parametrically,” and standardised in order to ensure cost-effective production. This involved the use of a three-dimensional virtual model, which was processed parametrically for integration into the data-controlled prefabrication process at the cladding supplier’s factory.
