The Grande Arbor: A Home Designed to Support Multigenerational Living

Cavco Industries introduced a new manufactured home prototype at the 2026 Innovative Housing Showcase in Washington D.C. to show what’s possible in innovative homebuilding. The Grande Arbor home broke new ground in construction and was designed to give growing, blended and multigenerational families more flexibility in how they live together. The home was designed with two Grande suites on opposite ends of the home, joined by common living areas in the center. 

For decades, manufactured homes have been built to sit on top of permanent steel chassis. The chassis is the heavy-duty steel frame that forms the home’s structural base and enables transport. The Grande Arbor prototype designed by Cavco is the first manufactured home built to the HUD Code engineered to stand without a permanent steel chassis frame. This means the home is set on the ground on a foundation like an onsite-built home — and that innovation opens a world of affordable housing opportunities for Americans. 

The Grande Arbor’s design is a genuine engineering milestone innovation, showing what’s possible in the near future for affordable housing solutions.

The Double Grande Suite: Made for Multigenerational Living

The Grande Arbor was designed to support multigenerational living. Blended family life is at an all-time high, with families living with grandparents or adult children under the same roof.  

More than 74 million Americans currently share a multigenerational household, and nearly one in five homes purchased in 2024 were bought specifically to support multigenerational living.  

Rising housing costs, aging parents, adult kids moving back home: the reasons for multigenerational living vary, but most of today’s housing floor plans haven’t caught up with the trending housing need. The double Grande suite was built to support family needs. Rather than the home having a single primary bedroom paired with a smaller second bedroom, the Grande Arbor design divides the home into two symmetrical wings, positioned on opposite ends with a shared kitchen, dining and living space in the home’s center. 

“This floor plan was all about creating a space where both bedrooms feel like primary suites,” said Saul Morales, the floor plan designer for the Grande Arbor. “Each suite has its own bathroom, walk-in closet with storage and privacy, with the shared living areas bringing everyone together in the middle.” 

Morales also recessed each bedroom wing about 12 inches from the exterior wall. It’s a detail he says most buyers won’t consciously notice – but they’ll “feel it, in the added architectural depth outside and the stronger sense of space inside.”

Two Innovative Firsts in One Innovative Home 

The Grande Arbor pairs an industry-first innovation below the floor with a layout built for how families want to live. Together, they open up new possibilities for manufactured housing – in how a home can be designed and built, where it can be placed and, most importantly, how well it can serve the people who will call it home.
