Backing onto the existing building on 34, rue Dombasle, the project is a six storey structure located at the corner of two streets which mirrors the design of the neighbouring building, without the seventh floor. The building’s lower section is made up of grey stone panels. The street-facing façade of the neighbouring school building aligns exactly with the rear of the new structure. The narrow, slender western façade thus serves as the figurehead for this corner of the plot. Occupying the corner of the built volume, it is the same height as the buildings along rue Dombasle. On the west side, the corner’s façade is glazed from top to bottom. The façade is composed of randomly distributed panels, and provides external spaces along its entire width. Large non-abutting sliding panels extending from floor to floor provide this side of the edifice with graceful proportions. This system of fixed and sliding, opalescent and transparent glass panels gives the narrowest of the corner façades a sophisticated evanescence.
On the north side, the six storey façade overlooking the street features a number of vertical, cream white limestone panels covering a single storey – some of them fixed, others sliding. Identical to one another, they form an untreated façade. The joinery is in anthracite grey aluminium on the outside, while the guardrails express the same vocabulary as the ones on the glass corner units, or, in other words, the glazed surfaces range in tone from opalescent to transparent.
The composition of the panels, bay windows, and balconies is synchronised, both horizontally and vertically, with that of the neighbouring façade, and the width of the three associated panels is equal to that of the columns defined by the large windows of the neighbouring building. Thus, by echoing its design and materials, the new façade mirrors the composition of the general façade of the plot on rue Dombasle.
