架构师提供的文本描述。一个年轻的成长中的家庭对扩大他们位于罗斯蒙特-佩蒂-爱国者的五层楼的想法感到兴奋。由于他们想留住楼上的房客，客户们同意牺牲他们后院的一部分来扩建。

Text description provided by the architects. A young growing family was excited about the idea of enlarging the ground floor of their 5-plex situated in Rosemont-Petite-Patrie. As they wished to keep their upstairs tenants, the clients agreed to sacrifice a portion of their backyard for the extension.

1350平方英尺的延伸部分，我们绰号为“沙发蛇”(花园蛇)，包括一个新的楼梯在一楼平面图，一个主卧室和一个浴室。由3间卧室和一个开放式概念浴室组成的“儿童区”在二楼占据着主导地位。

The 1350 sqft extension that we’ve nicknamed “the couleuvre” (the garden snake), includes a new staircase on the ground floor plan, a master bedroom and a bathroom. The ‘kids zone’, comprised of 3 bedrooms and an open concept bathroom, dominates the second floor.

建筑部分由一个棱角分明的黑色卷和白色斑点组成，它像蛇一样蜿蜒曲折，包裹在主卧室周围，里面包着从拆除旧车库中打捞回来的砖块。

The architectural parti consists of an angular black volume with spots of white, which twists and turns in a snake like manner, wrapping itself around the master bedroom clad in bricks salvaged from the demolition of the old garage.
