Multigenerational House Plans
Find the best multigenerational house plan options for your family. From single family residences with multiple en-suites to multi-unit options, we have options for every family in Boise, Mountain Home, and the whole Treasure Valley.
Stop modifying old houses to fit your family. Pathway Builders is a premier custom home builder specializing in "on your lot" construction in the Treasure Valley. We help you build specialized multigenerational house plans on your land that balance the right mix of shared family connection with individual privacy. Whether you need a main-level suite for parents aging in place or a separate unit for young adults, we have a solution.
While we encourage you to choose one of our established plans as a starting point to streamline the design process, we can customize any of our home plans to better fit your specific needs.
Key Design Features for Modern, Multigenerational Families
Our multi-gen home plans are designed to foster harmony through thoughtful layout choices rather than just adding square footage. We focus on proactive design that adapts to your family's needs today and tomorrow.
- Zoning for Privacy: Utilize separate wings or suites on opposite sides of the house to reduce noise transfer. Features like private entrances and sound-dampening technology ensure personal space, even when living under one roof.
- Proactive Design for Aging in Place: Choose single-story living for maximum accessibility, or ensure plans include a primary suite on the main level. Incorporate universal design features—like zero-step entries, wide hallways, and barrier-free showers—to avoid costly future renovations.
- Living Autonomy: Consider a mother-in-law suite featuring a separate sitting room and kitchenette, or a junior suite with a private bath for adult children.
- Structure Options: Decide between two buildings (primary home + ADU) for total autonomy, or one building with intelligently zoned shared spaces and a central kitchen.
Types of Multigenerational House Plans
As an experienced custom home builder, we know that no two families are alike. That’s why we offer flexible floor plans for every family dynamic. If you are considering building a multigenerational home on your land, you have many different options available to you, particularly if you are building a home on your land with acreage. The type of multigenerational floor plan you choose to build will primarily be determined by how independent your family is, what your privacy preferences are, how you want to use your home, and, potentially, zoning considerations in the area you choose to live.
Here are 4 options for multigenerational floor plans that we can build across Treasure Valley, Idaho.
Integrated Living All Under One Roof (Residence with Multiple Suites)
This multigenerational option keeps everyone under one roof in a single structure while maintaining privacy. These plans feature dedicated wings or suites—perfect for fostering relationships while providing personal space, especially for those needing accessible living. This integrated approach can be great when there are potential health concerns that reduce an older family member’s independence, while still fostering better relationships with shared spaces.
The Panorama: 3 Main Suites, Vertical Separation, Maximum Budget Efficiency.
The Ponderay Plus: Lateral Separation, Main-Level Junior Suite, 3,000 Sq Ft.
The "In-Between" (Connected Private Suite)
For a multigenerational house plan that offers a distinct "home within a home" feel, you may want to consider a multigenerational house plan with an attached mother-in-law suite. It is the perfect balance between everyone under one roof and living in completely separate buildings. A home with a connected private suite, especially if it includes a kitchenette, is ideal for those who want to maintain some independence, but still be close to the rest of the family.
The Pathfinder: Mother-in-Law Suite Upgrade, Kitchenette Potential, Semi-Independent.
The Compound (Primary Residence + Detached ADU)
For a multigeneration home plan with ultimate flexibility and privacy, pair a primary single family home with a detached Accessory Dwelling Unit (ADU). This can also be a great option for family that wants complete autonomy or if you envision your family’s use changing over time. The separate ADU can be rented out to another family, used as a short-term rental, or perhaps converted to a separate office if you no longer need or want to use it for multigenerational living. This is also an excellent option to turn your current residence into a multigenerational home. For more on ADUs, learn about the benefits of building an ADU in Boise or view our ADU floor plans.
The Piedmont ADU: Compact two-bedroom layout, ideal for maximum capacity
The Pinewood ADU: Spacious one-bedroom layout, ideal for luxury plan living
Two Residences On A Single Piece Of Land
This multigenerational living setup can be ideal for older generations with full independence or when your multigenerational living situation includes extended family members.
Depending on zoning laws and restrictions of your land, you may have the option to elect to build two separate single family residences on your land without dividing your land into separate parcels. ADU zoning and building restrictions vary by municipality across the Treasure Valley, but Pathway Builders has extensive experience navigating local regulations to maximize your property's potential.
