Non Conformist and Bold
This building is not lacking in self-confdence. As proof, you only have to take the second left along the Avenue de Longchamps from the Les Côteaux tramway Station in Saint-Cloud. No sooner have you left behind a quiet row of smart private houses in the traditional millstone grit Parisian style with front steps and plane trees than you come face to face with an odd-looking building, imposing but also childishly simple, more cubist than cube-shaped, decidedly “fashy”, evoking happy memories of a child’s toy.
An appealing, totemic building that you sense is designed for festive celebrations and young people, and that you might expect to fnd in Rotterdam rather than the uber bourgeaois St Cloud neighbourhoods. Even if it is only 300 meters away from OMA’s Villa Dalll’Ava.
With its cheerfulness and nonconformism, the building contrasts strongly with the urban development zone in which it’s located, behind a new block of private apartments and next to neo-Haussmannian offces and a day-nursery in a similar style. It is with the facing 1930s infant school that it empathises, extending the metaphor of the balcony courtyard, the passageways, the brick colour and the forecourt. As for the 1970s infant school next door, it maintains an obvious affnity with it in terms of shapes, only to dynamite the whole lot.
All in all it’s an odd little castle and cubist mountain, that owes its existence to the boldness of the Saint-Cloud Town Council, which has thereby acquired facilities that have revitalised its image and opened it to the most contemporary and positive architectural thinking.
Superimposed but not Separated
This brief provided a real headache: how to accommodate two autonomous programs on a narrow plot of land. KOZ chose to:
– Extrude the available area to the maximum height and hollow it out as with canyons that bring a clear and massive outdoor light deep inside the block.
– Superimpose the two programs without isolating them, by creating visual links between activities and applying the same principles on all facades and in all spaces.
The spaces are superimposed without being separated. They communicate via visual glimpses: you see each other on all sides, you ‘feel’ each other, you can easily fnd your bearings in a building with a spatially fuid but unfamiliar layout. Nevertheless, the functional and administrative autonomy of the two activities (separate entrances and different operational timetables) is respected.
A Pure Colour Scheme
The building uses colour very openly and assertively, with a wide palette ranging from red to green, by way of yellow, pink and orange. These colours cover the façade in wide stripes. Inside, the same colours are systematically repeated, like stepping in an oversized graffti.
The main facade is made of tinted glass with a colour gradient from red to green. The other 3 facades are more homogeneous, albeit coloured too.
A Sustainable Project
KOZ is part of the “environmentally aware” generation. The openings in the roofs and the glass facades bring maximum natural lighting everywhere to limit electrical consumption.
Concrete was chosen for the reasons mentioned above but the preference was for prefabricated concrete, generating less waste and spill.
The tinted glass facades provide good protection against setting sun and long-lasting colour. And of course all hot water is solar heated.
