Designed at the end of the 60s, the Macdonald warehouse extends along the southern side of the boulevard of the same name. The conversion of the industrial building into a residential, commercial, and office space implies an extensive modification of its structure. Partially hollowed out, the building now contains a two-floor interior courtyard at its center around which the residential units are arranged.

The landscape of this spacious courtyard, conceived of as a garden, contrasts markedly with the urban environment of the warehouse. A natural habitat is transposed within in an artificial manner. With no preconceived architectural design, the project leaves significant space to the random and unsystematic development of its plant forms. The residential units, immersed within this piece of reconstituted nature, become the privileged observatories of this plant development.

The technical constraints placed on this garden come from its environmental low carrying capacity. A layer of shrubs made up principally of rhododendrons imparts a shared character to the courtyard. Extending out in line with the poles of the base concrete slab, a layer of trees creates a play of vis-à-vis and transparency between the residential facades facing one another. The textures, colors, and flowering of the various plant varieties selected complement one another within the spaces. The diversity of broadleaved and evergreen varieties ensures, as in forest undergrowth, a quality landscape presence throughout the year.
