Floor Plans Perfect for Larger, Multigenerational Families (2024)

Multigenerational homes are one of the latest trends in homebuilding. Since the global pandemic, multigenerational home purchases have increased for a variety of reasons, the most important reason being to care for aging parents, followed by spending more time with family and cost savings.

With all that said, the trend toward multigenerational homes had begun before the pandemic, which tells us this trend is expected to continue post pandemic. Parents are moving in with their adult children to help them raise kids, to help manage healthcare issues, or just to be closer to their family in general. It’s also common for adult children to return home after college to save money on living expenses or to continue helping out around the house.

The benefits of multigenerational living are clear and varied. Whether it’s to share financial and homeownership responsibilities, to strengthen relationships, or to ensure the safety of the elderly and children, it’s also important for everyone to have their own space. Choosing a flexible design option allows for private retreats in the home that are essential for minimizing family tension and for personal well-being.

If you’re considering building a multigenerational home or just want to have that option in the future, consider some of these customizable floor plans. For the sake of convenience, we have organized the floor plans by our primary regions of the country: the Pacific Northwest and Central and Southern Arizona.

1. The 512 Suite

Before we jump into our multigenerational floor plans, we’d like to draw your attention to the 512 Suite for a very important reason: it can be added to most Adair Home plans. So, as you peruse the floor plans below, consider adding this fully functioning “home within a home” that includes a bedroom, full bathroom, kitchenette, and space for a stackable washer and dryer. Plus, it comes with its own entrance, making this addition perfect for independent living.

2. The Cascades

With 3,495 square feet of living space, the Cascades is the largest of our multigenerational floor plans. This home comes standard with four bedrooms and a loft, but you have the option to convert the loft into a second master suite. Having one of the master suites on the main level opens the possibility for single-level living for aging family members.

Having enough space for the family to gather for meals or quality time won’t ever be an issue with the Cascades. The spacious kitchen opens up into the nook, a place that would fit a breakfast table nicely. Beyond the nook, the great room stretches high into the open space of the second floor. Around the corner sits a cozy dining room with a window looking out onto the front porch and yard. The den can be used for a number of different activities, including relaxing, reading, and enjoying some television or a movie.

If your family still needs just a bit more space, a studio can be attached onto the house. For families with several drivers, another garage can be added to the final design.

3. The Mt. Rainier

At 3,217 square feet, the Mt. Rainier dedicates its living space to nearly any type of room you could ask for. The bedrooms are spacious and can be adjusted to your needs. For example, this home comes with the option of dual master suites, one on the first floor and one on the second (converted from the bonus room). But the customization doesn’t end there. The master suite on the main level can also be extended to include a sitting area and private entrance, providing plenty of living space and privacy for an older parent or adult child.

Other convenient spaces and rooms include the Jack-and-Jill bathroom, large mudroom with drop zone, den, kitchen nook, and loft space on the second floor. Each space is dedicated for a specific use, which means you never need to use a room for something other than its original purpose. If your needs expand beyond these, consider adding another garage or a studio to the final design.

4. The Ashland

Another multigenerational home with two stories, the Ashland has 3,136 square feet of living space and comes standard with two master suites and three additional bedrooms. Both master suites, one on each level, have the same layout with a large walk-in closet that can be extended to provide more storage space. Add the optional dual sinks for couples, or enjoy the extra counter space if only one person will be using one of the master suites.

The Ashland is one of the more special designs in terms of the number of customizations available. A large family means more food, which makes the kitchen pantry a great place to store nonperishables. A large family also means more community space, which makes the enlarged dining room a perfect addition to your home design. For those who love to lounge outdoors, the wraparound porch is a welcoming space. But we’re not leaving the indoor loungers out; the downstairs den is perfect for a media room.

For more space, be sure to add the third car addition to the garage or add on an attached studio to use as a guest room or storage space.

5. The Cashmere

It may have only a single level, but with 3,120 square feet, there is plenty of room for everybody in the family to find their own private corner in the Cashmere. The master suite, which includes dual closets, can include an optional door that opens to the back patio for private entry and exit. Consider upgrading the bath to a master bath for those who enjoy relaxing with a warm bath at the end of the day. Although only three rooms are marked as bedrooms in the floor plan, the bonus room can also be converted to a large fourth bedroom in its own corner of the house.

The kitchen is the space used most often by members of any household, so it’s important to make sure it has enough space. A large pantry and gourmet kitchen help to store a lot of food and ensure the right equipment is available for the number of family meals cooked each day.

The Cashmere is perfect for a big family, so be sure to anticipate the need for additional cars when the time comes by adding a garage to the final design. As everyone gets older, more space will be required, so consider the additional studio from the start.

6. The Mt. Hood

The Mt. Hood is a single-level floor plan with the option for two master suites, each of which can have its own separate entrance at the back of the house. The primary master suite is separated from the other bedrooms for the family members who need the most privacy. The second master suite can be converted from the bonus room without giving up space in either of the other two bedrooms.

The Mt. Hood emphasizes space in the common areas too. With two entrances, the dining room flows to the front door from one and the great room from the other. From there, the great room expands into the nook and kitchen. For those looking for a bit more elbow room in the kitchen, add a few feet to it. As with all our models, an additional garage and studio space works perfectly for a growing family.

7. The St. Helens

The St. Helens has a similar option for dual master suites in its 2,711 square feet. This single-level rambler works great for those looking for options to add more space and conversion to their home. The primary master suite can be extended, adding another 68 square feet to create a seating area, and the bonus room on the other side of the house can be converted to a second master suite without sacrificing any of the other three bedrooms.

One of the best features of this home is the openness. You might even consider the great room, dining room, and kitchen to be one big room. In the kitchen is a large walk-in pantry to store all the goods. For more space, consider the additional studio and garage.

8. The Creston

The Creston is a two-level, 2,512-square-foot floor plan that comes standard with five bedrooms, but two of the upstairs rooms can be converted to a second master suite. The master suite on the main level is the only bedroom on that floor, providing extra privacy and easy access to the kitchen and other common spaces. Upstairs, the second master suite sits opposite the bonus room, which can be used according to a number of different preferences. On the other side of the house sit the other two bedrooms, ensuring plenty of privacy all around.

As you can guess from the number of bedrooms, this home is for a big family, so the large kitchen and walk-in pantry are necessities. The same goes for the wraparound porch, which could be used as dining space in the warmer seasons.

9. The Jefferson

If you’re looking for a multigenerational floor plan option for a narrow lot, the Jefferson packs 2,222 square feet into two floors with a compact footprint. In the standard plan, all of the bedrooms are located upstairs, and you have the option to convert the loft to a fourth bedroom. The master suite touts dual closets; this is one of the few floor plans that does.

For an additional bedroom, you have the option to convert the den on the main level to a full bedroom with a full bathroom just across the hall. An entrance at the back of the house also provides the option for a semiprivate entrance and sitting porch. As with any large family, a spacious kitchen pantry is a necessity. Plus, with an open floor plan, the chefs of the house never need to be excluded from those in the dining room.

10. The Chapman

Standing at 3_,495 square feet, the Chapman combines modern luxury and charm with its open floor plan that touts vaulted ceilings. For families with elderly parents, this plan accommodates with the master suite on the main level. On the other side of the great room, opening into the kitchen and nook, is a den available for either a playroom or media room. For practical purposes, the mudroom comes with an optional bench and cubbies to make organization easy. The garage, which has an option for a third car bay, sits just outside of the mudroom.

Up the winding staircase, the second floor begins with a loft perfect for decoration and a space for the kids to play. You’ll find three bedrooms on this level. You’ll also have the option of turning the loft into a second master suite. In this scenario, the fourth bedroom becomes a bathroom.

11. The Pike

This one-floor, 2,711 square-foot, rambler-style home emphasizes space, relaxation, privacy, and customization. The Pike is designed as an open floor plan, so you might consider the great room, dining room, and kitchen to all be one room, which is great for spending time together. For extra privacy, the master bedroom, which can be expanded by four feet, stands separate from the other two bedrooms and bonus room.

The bonus room can be used as a media or playroom, but for families with elderly parents, this room is perfect for a second master suite. Additional perks of this design include an extension of the garage for a third bay and a covered patio in the back for the whole family to enjoy the weather when it’s warm.

12. The Benson

Perfect for a narrow lot, the Benson stands at 2,222 square feet and two stories. One of the perks of this home is its versatility. For example, the den on the first floor can be used as a place for the young ones to play, or it can be turned into an easily accessible bedroom for elderly parents. There’s also the possibility of turning the second-floor loft into a fourth bedroom. This home has options and works perfectly as a multigenerational home no matter what phase of life the family is in.
