What Are Multi-Family Homes?

With at least one shared wall between dwellings, our multi-family home designs provide separate accommodations for each household. They include duplexes comprised of two dwellings sharing one common wall, triplexes for three households, and quadplexes for four families.

At Design Basics, our multi-family house plans are available in a variety of sizes and styles to fit your needs. Whether you plan on renting out one or more of the residences, want to be close to an aging family member, or are just looking for a space-efficient housing option, we're here to help you build the ideal home!

Why Are People Choosing Multi-Family House Plans?

Multi-family homes are great solutions when land is limited or in areas with steep housing costs. This is because you're able to have multiple dwellings in one building that requires less land than detached homes.

Homeowners who want to earn some extra income and investors often choose multi-family homes because you're able to live in one of the residences while renting out the others.

Finally, those who may need to be close to an aging parent or other relatives, but still want plenty of privacy, space, and independence can also benefit from choosing one of our multi-family floor plans.

Design Basics is committed to helping you build a multi-family home tailored to your exact needs!

Types of Multi-Family Homes

Multi-family home plans are available in many different architectural styles and square footage sizes. Design Basics offers three configurations of multi-family floor plans.

29398 Flacco Twin / New for 2023 Duplex Home Plan


A duplex is a twin-residence house plan, joined together along one wall. Many of these designs feature a layout where both sides of the duplex are identical except they’re reversed (“flipped.”) Other duplex styles may appear as one, large family home with separate entrances.

Multi-Family Home Plan #29377


Triplexes or 'threeplexes' are comprised of three connected dwellings, typically laid out side-by-side. While not as common as duplexes or quadplexes, a triplex can be a great choice depending on the size of the lot and your housing needs.

29381 McAdoo Springs Quadplex Multi-Family Home Plan


If you opt for a quadplex or fourplex floor plan, the building will consist of four independent, but connected, residences.

Our in-line Quadplex home plans are built side-by-side.
