In 2005, Max Dudler built tHe Zurich Offices Of IBM. now the architect has added anOtHer building to the ensemble in Altstetten. With tHe new office building, Max dDdler was able to update the design of the IBM building in a surprising way. Originally planned as an annex, the new building now has its own address and individual expression.

In the development plan, as designed by Max Dudler in 2001, the building between the IBM building in the south and the Campi building in the west forms the northern keystone to the ensemble. Framed by the buildings, an urban park was established between the main building and the annex.

The new building’s design does not repeat, but instead varies the design language of the neighbouring IBM building, where stone and glass were used as materials. The window formats of the new building are identical in their proportion to the ones on the standard floors of the IBM building. Unlike this building however, which is divided into base, body and crest, the of ce building on Herostrasse features a horizontal stacking of floors. This horizontal structuring is emphasised by a marked shadow gap between the floors. The faces of the individual floors consist of a row of T-shaped elements separated by a fitting piece.

The of ce building’s facade is made of smoothed and polished artificial-stone elements with a high-quality surface and a consistent matt sheen. Thanks to this, the building’s appearance varies depending on the viewpoint. The artificial stone consists of a dark dyed concrete re ned with greenish-black natural stone aggregate. The material references the natural stone in the main building’s facade. The sharp-edged reveals were optically emphasised with a special acidi cation process. This accentuates the facade and makes the windows appear to be “carved directly out of the stone”. The visible elements of the window frames were also reduced to a technically feasible minimum, so that they are almost non-perceptible. The windows with external single glazing and internal triple glazing (closed cavity facade) provide the building with excellent thermal insulation and solar protection. To prevent condensate forming on the windows, the facade cavity is periodically pushed with purified dry air.

The main entrance and the side entrances of the classic three-tier design are set back into recesses flanked by large-format artificial-stone slabs. The facade material is mirrored, on a smaller scale, in the public areas of the building’s interior: the main and the side lobby as well as the entrance areas to the individual floors are fitted with detailed artificial-stone flooring and super-elevated skirting. They form a symbiosis with the wooden wall and ceiling panelling and give the areas a special quality. The prestigious main lobby is additionally enhanced by the carefully selected natural-stone cladding of the lift core. Marble from the Aosta Valley was hung in a mirror pattern that is evocative of the of ce lobbies familiar from New York or Chicago.
