Prefab triplex: three homes, one lot

A triplex is three homes on one lot, built as a single cohesive building. In a prefab triplex, the homes are made as factory modules or panels and then set and finished on your land. It is the natural next step up from a duplex when you need room for a third household or an extra rental home.

How a prefab triplex is arranged

The three homes usually share walls and are stacked and mirrored to fit a standard lot. A common pattern is two homes reached from the street and a third reached from a rear lane. Each home has its own entrance, kitchen, and bathrooms, so the three households live independently while sharing one lot. From the street, a good triplex looks like one large, modern house rather than three separate buildings.

Who a prefab triplex suits

• Parents with two grown children who each want their own home nearby.
• An owner who wants to live in one home and rent the other two.
• Three related households pooling resources to afford a better neighbourhood.

If two homes are enough, a duplex is simpler. If you need a fourth home, look at a prefab fourplex.

Why prefab for a triplex

A triplex has more moving parts than a duplex, so the time savings from building off-site add up. The three homes can be made in the factory while your lot is prepared, then set quickly. That keeps a larger project on a more predictable schedule. See prefab vs traditional and the timeline for detail.

Cost of a prefab triplex

The lot cost is shared across three homes, which lowers each household's share of the land compared with a duplex. The building cost is higher than a duplex because there are three homes, but lower than a fourplex. For real ranges, read the prefab multiplex cost guide, and see how families fund the build.
