The Saint-Georges Center contributes in a confident yet discreet manner to the revitalisation of a previously neglected urban quarter close to the city centre of Geneva. The new structure replaces the north wing of a three-part office ensemble from the early 1960s. The eight-storey building nestles against the existing ten-storey main structure with a form that gently curves towards Boulevard Saint-Georges, establishing a certain autonomy in the urban setting. The treatment of the ground floor follows its own logic, whereby the canopy line of the neighbouring building is picked up and emphasised to create a clearly marked entrance: the ground floor walls recede, drawing the street space inwards, while the upper floors curve out towards the general building line. The façade displays a range of reddish tones leading into greys, in response to the colouration found in the immediate city context. The variations in physical depth and colour saturation of both vertical and horizontal elements generate the impression of an immaterial space of colour within the façade, which changes dynamically as the observer alters position. The façade profiles on the south of the building towards the interior of the plot are deeper so as to function as a brise-soleil, optimising passive solar performance.

The outer skin of the building has all the attributes of a contemporary, intelligent exterior skin, including highly insulating multilayered glazing and external solar protection. Additional contributions from active building components and the use of geothermal energy have resulted in the building being awarded a Minergie certificate under Swiss sustainability standards.
