The open architecture called “Lejeune Residence” has revitalized a once neglected maisonette building in Montréal into a single-family home with flexible interiors and an outdoor garden. The open spaces were organized in such a way that a subtle distinction between inside and outside is possible. During the summer, the living room furniture is brought outside onto the terrace, which is on the same level. This natural extension of the home’s living space allows owners to enjoy the outdoors, and even in the colder months, the fireplace and garden can be enjoyed both inside and out, blurring the lines between the two. The kitchen, dining room and living room have been realized as a single space, while the materials and colors of the furniture define different areas and improve the feeling of fluidity in the interior.
