One roof, three generations: designing for everyone.

Suites, laneways and main-floor bedrooms: how Vancouver families are building for three generations, the design details that preserve privacy, and the cost math versus assisted living.

The fastest-growing brief we receive isn't a bigger house — it's a smarter one: grandparents close but independent, adult kids launching slowly, one property working for three generations. Here's how these homes get designed, and the cost math that surprises every family.

The math families run too late

$3000$6000$9000Assisted living, private (monthly)Assisted living, private (monthly): $5,000–$8,500 /mo$5,000–$8,500 /moGarden suite at home (amortized)Garden suite at home (amortized): $1,800–$2,700 /mo$1,800–$2,700 /mo
Representative comparison: private-pay assisted living versus amortizing a $450k–$600k garden suite over 25 years. The suite is an asset that appreciates; the fees are not.

A laneway or garden suite costs serious money — and still runs a third of assisted-living fees, while adding permanent value to the property. When the suite is eventually vacated, it becomes rental income. No monthly fee ever does that.

Three configurations that work

The garden suiteMost independent

A laneway or garden home gives parents a front door of their own — closeness without cohabitation.

The main-floor wing

A bedroom, barrier-free bath and laundry on the entry level — the house works for decades of knees, strollers and everything between.

The legal suiteMost flexible

Starts as a mortgage helper, becomes a grandparent suite, ends as a launching pad for adult kids. Build it legal on day one.

Design details that preserve the peace

  • Separate entries and sound separation — privacy is acoustic before it's spatial; party assemblies get real attention.
  • Barrier-free by stealth — zero-step entries, 36-inch doors and blocking for future grab bars cost almost nothing during construction.
  • Kitchenettes done legally — what counts as a second kitchen affects suite status; we design to the rulebook.
  • Shared outdoor rooms — one good courtyard or deck between homes does more for family life than any interior plan.

Start with the family meeting, not the floor plan. The best multigenerational projects begin with everyone's honest needs on one page — we facilitate that conversation as part of design, gently.
