As families grow more connected and housing costs rise, more people are embracing multigenerational living—where two or more generations live under one roof. Custom homes are uniquely positioned to make this lifestyle not only practical but enjoyable for everyone involved.
Whether you’re planning to welcome aging parents, support adult children, or create a flexible home for the future, designing with multigenerational needs in mind can lead to a more harmonious and functional household.
Here’s what to include in your custom home to support multigenerational living, plus tips on how to get it right.
Why Multigenerational Homes Are on the Rise
- Aging in place: Baby boomers prefer staying with family over moving into assisted living.
- Financial benefits: Families can share mortgage, utility, and maintenance costs.
- Childcare support: Grandparents can help with children, and grown children may help with caregiving.
- Cultural values: Many cultures prioritize extended family living under one roof.
In short, it’s a lifestyle that fosters closeness, convenience, and cost-sharing—but it requires thoughtful design.
Key Design Elements for Multigenerational Homes
1. Separate Entrances or Wings
Whenever possible, design private entrances for in-law suites or lower-level apartments. This allows for privacy and autonomy while keeping everyone under the same roof.
Design ideas:
- Side entrances
- Basement walkouts
- Separate garage entries leading to private quarters
2. Dual Primary Suites
Two fully equipped primary bedrooms with en-suite bathrooms offer comfort and dignity for both older and younger adults. Locate them on separate floors or wings of the home for added privacy.
3. Flexible Common Spaces
Open living and dining areas should accommodate larger groups, but also offer options for quiet time or smaller gatherings.
Include:
- A spacious kitchen with dual ovens or refrigerators
- Living rooms with multiple seating areas
- Optional dens or TV lounges in multiple parts of the home
4. Secondary Kitchen or Kitchenette
A separate kitchen or kitchenette in a private suite enables grandparents or adult children to cook independently.
Features to consider:
- Compact appliances
- Small sink and microwave
- Separate pantry or cabinetry
5. Soundproofing and Zoning
Sound management is essential in multigenerational homes. Use insulation, thicker doors, and smart layout planning to minimize noise transfer.
Also consider zoned HVAC systems so different areas can be temperature-controlled to suit individual comfort levels.
6. Accessible Design
If you’re accommodating elderly parents, incorporate universal design features that promote aging in place safely.
Examples:
- Zero-step entries
- Wider doorways and hallways
- Walk-in showers with grab bars
- Lever-style handles and smart lighting
7. Multipurpose Rooms
Add rooms that can shift use as family dynamics change. For example, a home office can later become a nursery or a private sitting room for grandparents.
8. Extra Storage
Multigenerational living means more belongings. Plan for ample storage throughout the home:
- Oversized closets
- Built-in cabinets
- Attic or basement storage
- Mudrooms with lockers or cubbies for each generation
9. Outdoor Living Spaces
Design outdoor areas for shared enjoyment and retreat. This could include:
- Covered patios with separate seating areas
- Garden space for grandparents
- Play zones for children
- Private balconies off in-law suites
Legal and Zoning Considerations
Before breaking ground, check local zoning regulations. Some areas have restrictions on secondary kitchens, in-law suites, or multi-family-style layouts. A good architect or builder familiar with your area can help you stay compliant.
Should You Build Up or Out?
This depends on your lot size and family needs:
- Building up (two stories): Keeps the footprint small, ideal for separate living zones on different floors.
- Building out (ranch style): Offers better accessibility and single-level convenience, especially for older adults.
Final Thoughts
Designing a custom home for multigenerational living isn’t about making compromises—it’s about enhancing connection, comfort, and independence for everyone under one roof. With the right features and planning, your home can be a place where multiple generations not only coexist but thrive.
