Narrow Passive House by One SEED (www.oneseed.ca) The clients are a young and visionary couple, pregnant with their first child, who wanted to do something different. A tight budget meant they needed the flexibility to maximize rental income with a secondary suite now, but also to accommodate a growing family down the road. Small bedrooms promote a tight-knit family by dedicating square footage to one large gathering space which includes the kitchen, dining, living, and a work station. There are no separate TV rooms, offices, or dens. The basement suite has two bedrooms, however one or both bedrooms can be re-assigned to the house, creating a studio apartment with a private sleeping space as needed.
