Quebec-based architectural studios blanchette archi.design and MDTP atelier d'architecture have completed Éléonore, a 15-storey rental residential building on the banks of the Ottawa River in Gatineau, Quebec. The building design is the result of a collaboration between the two studios; the interiors of the residential units and communal areas were designed by blanchette. Éléonore embodies the studios’ joint commitment to rethinking urban spaces and enhancing collective living. This is achieved through a harmonious blend of heritage preservation and contemporary architecture. Developed in partnership by Oktodev and Endevco, Éléonore includes the integration of two heritage buildings, restored as part of the project.
Collective living
The 5,097-square-metre building’s design prioritises collective living and well-being, featuring 242 apartments and various shared spaces. A gym, self-service library, dog park, and co-working spaces enhance everyday living. A third-floor terrace with an outdoor dining area encourages social gatherings, while a rooftop pool and panoramic terrace provide views across the Ottawa River.
Design rooted in an evolving urbanism
The 15-storey building (plus three underground parking floors) comprises two volumes, each with a distinct materiality: one is clad in red bricks, echoing the existing typology of the district, and the other is clad in aluminium, with a light, reflective anodised colour. This metallic volume provides a backdrop to the site’s two heritage houses; set on a brick base, it establishes a strong visual connection with the first volume.
Along one side of the building, on rue Notre-Dame-de-l’Île, the base is made up of a row of townhouses. Benefitting from additional height and direct access from the street, these ground-floor units ensure a smooth transition with the evolving urban fabric. The base extends northwards, creating a third-floor communal terrace.
Éléonore’s bright, double-height lobby has an abundance of windows, fostering a strong link with the outdoors. The landscape design includes a public plaza and structural colonnade, connecting the public and private spaces. The project seeks to promote social inclusion and community engagement, offering gathering spaces accessible to all.
Eléonore’s architectural design is rooted in an evolving urbanism. The building relates to newer structures of more than ten storeys and to older houses that are an integral part of the landscape.
“The project's site integration and volumetric approach reflect a sensitive response to the context, honouring the site's history, while asserting a contemporary architectural identity,” explains David D. Boisseau, associate architect at blanchette archi.design.
“With an integrated approach, Éléonore strikes a balance between heritage preservation and architectural innovation," adds Audrey Patenaude, associate architect at MDTP atelier d'architecture. “This project underscores our commitment to designing spaces that respect their environment while addressing contemporary housing needs.”
A dynamic architectural expression
Éléonore’s staggered balcony design creates a rhythmic effect on the longitudinal elevation of the aluminium volume. This anodised metal cladding captures colours and reflections as they change throughout the day, giving the structure a vibrant and dynamic architectural expression. The custom-designed, ceramic-fritted balcony screens further enrich the building’s aesthetic. Narrower facades feature loggias and open-air walkways, while strategic setbacks align with the surrounding urban scale, ensuring the building’s cohesive integration.
“Éléonore is an ambitious project that demonstrates our ability to combine design excellence, efficiency, and respect for the existing architectural framework,” says Patrick Blanchette, senior architect and associate president at blanchette archi.design. “It reflects our signature approach to innovative and sustainable design.”
Éléonore is named in honour of the founder of a red-brick, three-story monastery located on nearby Laurier Street.
The project aims to achieve LEED Gold certification, reinforcing its commitment to sustainability and energy efficiency.
