Sutton House in Quebec’s Eastern Townships underwent a complete overhaul and is an extension of an early 20th-century stone house.
The overhaul involved conserving as much of the original building and structure as possible while entirely reorganizing the inside, improving thermal efficiency, and expanding the ground floor.
The firm, Pelletier de Fontenay, developed custom white cementitious coatings that cover all old and new facades and all the walls inside the house. These lime and cement coatings, developed in close collaboration with local artisans, provide a subtle, tactile finish that will continue to glaze over time. The facades were designed to help regulate the climate according to the season.
Together with restoring the historic masonry, the team also replaced all the deteriorated doors and windows with new high-performance wood windows in line with the new insulated layer.
In order to preserve the monolithic aspect of the walls and protect the stone from possible decay, the entire house and addition were insulated from the inside with a new hemp layer, a bio-sourced material known for its breathability and humidity control.
Inside, the interior walls were lined with a vapour barrier and parged with a natural lime finish.
A fully glazed roof dormer opens above the original addition on the upper floor. Behind the house, the new chimney extends vertically well above the roof.
The walls and roof of the ground floor addition are deep and thick. Three blocks containing storage and a fireplace frame views of the surrounding landscape and support a large overhanging roof, extending the living spaces outwards onto a series of terraces, pathways, and gardens.
What is the estimated cost? We are going through a restoration or tear down dilemma.
