867 De Bougainville is a minimalist house located in Quebec, Canada, designed by Bourgeois/Lechasseur Architects. The project is a complete remodelling of a ground floor apartment in a building dating back to 1924, located in Quebec City’s Montcalm neighbourhood. The clients, a young family, decided to convert the ground floor into their main residence. The space was remodeled to make it airy, bright and more functional. The living areas are spread out through a large linear area crossing the building from east to west. Now the light flows in more freely. During the demolition work, a brick common wall was seen as an element of interest to be kept and enhanced.
