Next to the Temple de Champel stands a residential building constructed in 1950 by Georges Addor. It is, in a way, a symbolic construction which combines the two faces of Champel: the upper part of the block is neat, yet quite conservative, while its lower section is uncompromisingly modernist.
The building's first floor is entirely occupied by the parish common room and used by the adjacent Temple. As it is moved forward in relation to the rest of the building, its frontal part is supported by concrete pillars, which create a slight resemblance with El Lissitzky's Horizontal Skyscrapers (albeit this one carries a building on its top). The modernist part of the building has some interesting details: its wall facing plateau de Champel is furnished with a long strip of windows while its south-west side is decorated with a bronze sculpture created by Paul Bianchi.
The reason why this block of flats is composed of two totally different parts is clear when one looks at its surroundings: on one hand there is the low, modernist Temple and on the other, there are the tall, traditional residential buildings. The lower part of our house nicely reflects its liturgical neighbour, whereas the upper part is in line with the general style of the adjacent properties. In this way Avenue Dumas 2 does not break the coherence of the area and at the same time manages to retain an original, modern character.
