The Langlois-Lessard residence in Léry

A successful integration on the shore of Lake St. Louis

Via v2com

Located in a flood zone along the shore of Lake Saint-Louis, the design of the Langlois-Lessard Residence is a direct response to the questions that where raised during the visit to the site. The reflections included how to integrate architecturally with an exceptional natural site and how to define the spatiality of the house, its volume and its fabric, in response to the site itself.

Langlois-Lessard house - WestmountMag.caTo preserve the pristine beauty of the site and its many mature trees, a compact footprint was adopted by the architects, Chevalier Morales, keeping the pool integrated with the house through a low horizontal wall of natural stone, which also ensures intimacy. Only seven percent of the site is built upon. Oriented towards impressive views and sunsets, the residence – benefiting from an acquired right – is sited near the water, creating the impression from within that the interior spaces are unfolding onto the lake.

Both the exceptional quality of the landscape and solar orientation of the site guided the general planning of living spaces on both floors. As the project progressed and was refined, many architectural elements come to define the spatial identity of the house.

First, an open fireplace sits on the axis of the main entrance, at the heart of the volume, while service blocks detached from the exterior walls flank its sides, creating subtle sculptural volumes. Next, each floor is characterized by a remarkable spatial openness, yet the two are only connected through a very narrow and minimalist staircase.

Given the water’s proximity and the elusive nature of the horizon beyond, the ground floor was imagined not only without double-height spaces but additionally with a relatively low ceiling, reinforcing the view towards the horizon. Inversely, on the second floor, the bedrooms enjoy interesting angular ceilings that generate a whimsical play of light and shadow.

Langlois-Lessard house - WestmountMag.caThe volume of the house follows from two principles: to offer intimacy to the owners and to react to the strong winds that originate in the west. The relatively opaque stone base offers the required intimacy, stretching along the pool while also establishing an artificial horizon on which the upper volume lies. The latter is displaced to offer a covered terrace protected from the sun on the poolside. The roof has been shifted and angled in response to the surrounding nature environment. This pushing of the upper volume towards the interior of the site generates both a protection of the main entrance while on the side of the site, it creates a counter-effect, projecting the dining room towards the lake.

Langlois-Lessard house - WestmountMag.caThe elaborate integration of natural textures comes from an acute observation of the surroundings and the general character of the city of Léry. Roughly shaped natural limestone, hemlock-textured concrete, and wood siding all work together to integrate the house to the natural tones of the site which are characterized by the bark of surrounding trees, the neighbouring houses’ wood siding, stone walls and even the various other waterfront walls constructed of concrete block.

Inside, the polished concrete floor and concrete fireplace dominate the material palette while the furniture softens and adds to the tone-on-tone effect. The neutral palette allows place for the surrounding landscape and its shifting seasonal experience to penetrate within.
