Designing for Generations: What to Ask Custom Builders Adelaide Before You build together

Multigenerational living is becoming more common in Adelaide.
Whether its aging parents moving in, adult children returning home, or families pooling resources to afford a better lifestyle—more people are sharing space across generations.
And with that shift comes a different kind of build.
You’re not just creating bedrooms and bathrooms. You’re designing for independence, privacy, accessibility, and long-term liveability—all under one roof.
That’s where working with custom builders becomes essential. Off-the-shelf plans rarely work for three or more generations. But with the right questions up front, a custom builder can help you create a home that balances togetherness and separation perfectly.

1. Can You Help Us Design Separate Living Zones?

One of the most important features in a multigenerational home is separation. Each generation needs its own space—not just for sleeping, but for living.
Ask your builder:

• Can we include a second living room or media area?
• Can the floorplan support two master suites?
• Is it possible to add a self-contained wing or guest suite?
• Can you help us zone the house so areas can be closed off when needed?

Adelaide’s best builders can design from scratch, they’re well-placed to make sure each generation has the space they need—without making the home feel fragmented.

2. How Can We Maximise Privacy Without Sacrificing Connection?

Privacy matters. But so does staying connected.
It’s a tricky balance, one that experienced custom builders know how to manage.
Ask:

• How can we soundproof bedrooms and living spaces?
• Can we separate entrances or outdoor areas?
• What internal layout helps minimise foot traffic through shared zones?
• How can we design shared kitchens or laundries for dual use?

Thoughtful design can reduce friction and give everyone their own retreat. Look for builders who’ve done this before and can show you real-life examples.

3. Can You Make the Home Adaptable Over Time?

Multigenerational needs aren’t fixed. Children grow. Parents age. Life changes.
That’s why flexibility matters more than anything else.
Ask your builder:

• Can this area be converted into a separate apartment later?
• Is the ground floor fully accessible for older family members?
• Can we install wider doorways or ramps now, even if we don’t need them yet?
• Are there any smart ways to future-proof the floorplan?

Custom builders who specialise in long-term liveability can guide you through these decisions—helping you avoid expensive renovations down the track.

4. How Do You Approach Accessibility?

If part of your multigenerational plan involves elderly relatives or people with mobility issues, accessibility needs to be built in from day one.
Ask:

• Can we include a step-free entry and wider hallways?
• What bathroom features support aging in place?
• Are lever-style handles, and low-threshold showers included?
• Is there enough space to move easily between rooms with a walker or wheelchair?

These features don’t need to make the home look clinical. Many custom builders now offer accessible design that still looks modern and welcoming.

5. Can We Add a Second Kitchen or Kitchenette?

Having two cooking areas makes life easier when people live under one roof but keep different schedules or dietary needs.
Ask:

• Can we fit a kitchenette into a second living area?
• What plumbing and power requirements should we plan for?
• Will this affect our council approval or zoning?

A second kitchen doesn’t have to be large. Even a small wet bar or galley space can reduce strain on the main kitchen—and give older parents or grown children more independence.

6. What Are the Best Ways to Manage Energy Use?

More people means higher energy demand. But smart planning can keep running costs under control.
Ask your builder:

• Can we zone heating and cooling for each living area?
• What energy-efficient systems can we install to reduce costs?
• Will you include solar, battery storage, or EV charger wiring?
• Can we install smart thermostats and lighting to manage usage?

Many of Adelaide’s best custom home design builders are leading the way in Australia for energy-efficient design. They can help you future proof your home for rising energy prices and environmental impact.

7. How Will You Design for Shared Outdoor Space?

Outdoor areas in multigenerational homes need to serve a lot of purposes—relaxation, play, privacy, and entertainment.
Ask:

• Can we divide the backyard into usable zones?
• What’s the best way to add multiple seating or dining areas?
• Can we include a granny flat or studio in the design?
• What landscaping options improve accessibility and shade?

Builders who understand multigenerational needs won’t just think about the house—they’ll help you make the whole block work harder.

8. What Will Council Allow on Our Block?

Rules around dual living, studios, and second kitchens vary between councils—and can change depending on your block’s size, slope, or zoning.

Ask your builder:

• • Have you worked with this council before?
  • Can you handle the approvals process for us?
  • What are the local requirements for secondary dwellings or extensions?
  • Will our plan be subject to planning restrictions?

Experienced builders know how to navigate local red tape. They’ll be upfront about what’s possible—and help you avoid costly delays.

9. Who Will Be Our Main Contact Throughout the Build?

Communication is key on any project, but especially on a complex build like this.
Ask:

• Will we have one point of contact throughout the build?
• How do you handle design changes mid-build?
• How often will we get updates or site access?
• Can we sit down regularly to review progress?

Multigenerational builds involve more voices and more decisions. You want a builder who’s organised, transparent, and proactive.

10. Can You Show Us Examples of Other Multigenerational Homes You’ve Built?

Don’t settle for theory. Ask to see real builds.
Look for:

• Completed homes with a similar number of residents
• Floorplans that reflect separation and shared zones
• Design features that prioritise accessibility and adaptability
• Homeowners who can share their experience
