‘It is remarkable that the building elements bring with them a surprising lightness despite their large formats,’ says Ulrike Dix, the lead architect, also confirming the filigree appearance of the sliding elements, each weighing 700 kg. On the ground floor, another cero sliding window provides a seamless transition between the catering area and the outside, which can be opened to its ،mum extent thanks to a wall pocket attached to the room. Great views both in and out then, at this new-old landmark in the centre of Berlin.
