This site is the hub between the new district and the city. It is located among other large office programs organized at the end of a planted mailbox and overlooking the RER rail network. From here opens up a view of old Massy. The triangular shape of the plot creates a 360° interaction with the context.

Within a volume composed of rasterized office trays, a few "formal events" of exceptional dimensions are inlaid, both inside and outside. They dig into the form to establish a dialogue with the landscape. They are also perfect spots for relaxation... A patio nestles in the heart of the building, perceptible from the streets through three monumental entrances. In their lower part, the façades have an inflection to expand the public space.

The curtain wall of the facade, with invisible fixing, is of "ventilated" design. Silkscreened on all sides and with large facets in places, it transforms the appearance of the volume into a smooth and mysterious monolith.

The architecture is as if sculpted, like an identifiable prism on the renovated peri-urban skyline. Abstract and immaterial during the day, at night the interior is visible, a luminous landmark witnessing domestic use.
