Ateliers Castelnau

The project consists of three pavilions, including the neighbouring cooperative's development, which is an integral part of the overall plan. These structures frame Castelnau Street West and the new courtyards opening onto that same public road. In continuity with the materiality of nearby buildings from the Atelier Castelnau project, the use of both light and dark tones, against the more neutral nature of the grey stone, provides a unifying thread with the adjacent heritage ensemble. The pavilions are physically connected, forming a coherent and integrated whole. The interweaving of the main pathway with the built volumes breaks up and animates the façades, especially along the western courtyard where the main entrances and circulation paths are concentrated. 

The distinct entities include mezzanines, the main entrance hall to the overall complex, and the building housing the community housing units. The articulation of the private spaces draws inspiration from the printing activities that once occupied the former workshop building and the site over time. Echoing the techniques of positive and negative printing, the façades facing the street and courtyards feature contrasting outdoor private spaces: recessed loggias and projecting balconies. The loggias minimize the visual impact of residential occupation on the public realm, while the balconies enliven the courtyards and outdoor spaces at the heart of the block. At ground level, a shared gym for all residents opens onto both the southern courtyard and the rear garden. The contemporary architectural language is conveyed through the choice of materials and the composition of volumes. Rooftop mechanical equipment is set back from the façades. The entrance hall is also set back from the upper floors and features three fully glazed façades.

In line with the overall site plan, the positioning of the Phase 2 building of the Ateliers Castelnau project completes the southern courtyard with the construction of a second building forming three wings: one along Waverly Street as a backdrop, one perpendicular to Castelnau Street, and the third fronting Castelnau Street itself. The placement of the Phase 2 building helps enclose the southern courtyard, enables the layout of the rear garden, and ensures clear separation from the future Phase 3.
