Pair of prefab homes ‘intertwine’ on a single lot

One lot, two homes—that was the directive for this compact site in downtown Toronto. To make the most of the 25-foot wide lot, the architects at Baukultur/ca designed two semi-detached prefab homes that are slightly offset instead of aligned side by side.

The duo of three-story houses interlock, sharing a wall in the middle. One of them soaks in the street view, while the other looks out onto a backyard (yet preserves a “front” entrance, just a little more set in from the sidewalk).

The project, another handsome exercise in bringing a bit more density to tight urban lots, leaves plenty of space for both abodes, each of which features a spacious living room, modern kitchen, and plenty of windows to bring in natural light.

It’s an efficient design made all the more efficient by prefab construction. The architects decided to build the walls and ceiling panels offsite in a factory, allowing them to complete the building envelop in just five days and keep construction noises to a minimum.
