More of the families we build for are planning for more than a couple and their kids. Aging parents, adult children who move back for a while, a live-in caregiver, or simply the wish to have everyone under one roof at the holidays — the multigenerational home is quietly becoming one of the most requested things we design.
Done well, it feels generous rather than crowded. The catch is that it has to be planned that way from the start; you cannot easily retrofit privacy.
A second suite, not a spare room
The heart of a multigenerational plan is usually a true second primary suite — its own bedroom, full bath, and often a sitting area or small kitchenette — positioned for privacy rather than tucked in as an afterthought. Whether it reads as an in-law quarters or simply a dual primary, it lets two generations share a home while each keeps a real retreat.
Put a bedroom on the main level
A main-level bedroom and full bath is the single most useful move for a home meant to last. It serves guests and grandparents now, and the owners themselves later, without a staircase becoming the thing that forces a move. Designed in from the start, it never reads as a compromise.
Shared and private, on purpose
The best of these homes breathe between together and apart. Generous shared spaces — a great room, a big kitchen, a covered patio — pull everyone in, while bedroom wings sit far enough apart that no one hears anyone else's morning. A separate entrance, a second laundry, or a quiet coffee bar upstairs can be the difference between coexisting and actually enjoying it.
Quietly built to adapt
Good multigenerational design borrows from universal design without announcing it — wider doorways, a curbless shower, blocking in the walls for a future grab bar, a bedroom that could become a study. None of it changes how the house looks or feels. All of it means the home can keep pace with the family living in it.
Plan for the life, not the layout
The right plan starts with how the household actually lives — who needs privacy, who needs help, who visits and how often — and works back to the walls. Start there, and a home for several generations stops feeling like a compromise between them and starts feeling like it was built for all of them.
