Granny flats have come a long way, no longer the makeshift backyard structures of decades past, but fully realised secondary dwellings that balance style, function, and long-term value. In 2025, these compact homes are becoming smarter, more beautiful, and more desirable than ever. Whether you’re building to accommodate family, generate rental income, or simply make better use of your land, understanding the latest design trends will ensure your space meets modern standards and expectations.
For those planning to build granny flats Melbourne, staying ahead of these trends not only adds comfort and style but it also directly impacts resale value, rental demand, and livability.
Let’s explore what’s defining 2025’s best-designed granny flats, with a focus on layout innovation, natural flow, and smart integrations that work particularly well in Melbourne’s climate and property market.
1. Multi-Functional Open-Plan Living
In a compact footprint, open-plan designs are no longer optional; they’re essential. But in 2025, these layouts are getting smarter. The living, dining, and kitchen areas seamlessly coexist, supported by hidden design enhancements that maximise space:
- Moveable walls or pocket sliding doors to create instant privacy or open flow
- Built-in bench storage and shelving in unexpected places
- Wall-mounted media units that free up floor area and reduce visual clutter
This kind of layout makes even a 1 bedroom granny flat melbourne feel like a full-sized home, ideal for independent living, extended family, or even short-term rental.
2. Integrated Outdoor Spaces That Extend Living Areas
Melbourne’s lifestyle encourages outdoor living year-round, so in 2025, outdoor integration has become non-negotiable. Today’s top granny flats offer a seamless flow between inside and out, thanks to:
- Wide stacking or bifold doors that completely open up the living space
- Low-maintenance timber or composite decking
- Covered alfresco areas with outdoor lighting and built-in heating
These outdoor features aren’t just about aesthetics; they enhance the livable space and appeal to both tenants and future buyers. Innovista’s Lana Series includes optional decking with privacy screens, allowing you to enjoy the outdoors even in close suburban settings.
3. Natural Light And Airflow As Central Design Elements
As block sizes shrink, getting enough light into a granny flat is a growing challenge. That’s why the best 2025 designs are using a combination of architectural and material techniques to make interiors brighter and healthier:
- Highlight and clerestory windows that invite soft daylight
- Skylights in bathrooms and kitchens make rooms feel larger
- Corner windows and large sliders that enable cross-ventilation
These features are especially crucial in granny flats Melbourne, where the seasons vary dramatically and good airflow can significantly lower energy costs.
4. Compact Kitchens That Don’t Compromise On Style
Kitchens are still the heart of any home, even in a 60m² space. In 2025, compact kitchens are not only smarter but visually stunning, with key trends including:
- Full-height cabinetry for vertical storage
- Integrated appliances like drawer dishwashers and slimline ovens
- Curved island benches that soften the layout and improve movement flow
- Premium finishes such as sintered stone, matte cabinetry, and brushed metallics
Innovista’s Luxe kitchen packages reflect these choices with LED splashback lighting, pendant task lighting, and space-savvy layouts ideal for long-term use in both rental and owner-occupied dwellings.

5. Spa-Like Bathrooms With Big Impact
Modern granny flat bathrooms are prioritising both elegance and efficiency. Despite limited space, top designs in 2025 feature:
- Frameless walk-in showers that reduce visual barriers
- Floating vanities with underlighting for a luxurious feel
- Large-format tiling for a seamless, expansive look
- Smart mirrors with touchless controls, lighting, and demisters
These features are ideal even in a 1 bedroom granny flat melbourne, making the space feel premium and future-ready.
6. Smart Home Features And Energy Monitoring
Energy efficiency and tech integration have moved beyond trend; they’re now a baseline. More homeowners are requesting:
- Digital door locks and private entry keypads
- Smart security systems with remote monitoring
- App-controlled lighting and air conditioning
- Solar and battery-ready builds for sustainability
In line with this, Innovista includes 7-star energy compliance as standard and offers smart tech packages designed around lifestyle goals, perfect for investors and multi-generational families alike, reinforcing why granny flats are the future of multi-generational living in today’s evolving housing landscape.e.
7. Interior Design That Prioritises Calm And Comfort
Interior schemes have taken a soothing turn in 2025, with many homeowners gravitating toward Japandi, Scandinavian, and coastal-inspired palettes. Expect to see:
- Neutral tones like soft beige, warm whites, and earthy greys
- Natural materials, including oak-look flooring, rattan accents, and linen curtains
- Matte black fixtures for contrast without overwhelming the space
Innovista gives homeowners the choice of light or dark scheme packages, making it easier to align the granny flat’s aesthetic with the main residence or rental expectations.
8. Accessibility and Age-Inclusive Design
With multi-generational living on the rise, accessibility is no longer optional; it’s integral. Modern granny flats Melbourne are being built to suit ageing residents, mobility-limited occupants, and families planning for future-proof homes.

While some may think a single-bedroom granny flat is too limited, 2025 design trends prove otherwise. A well-designed 1 bedroom granny flat melbourne can include all the hallmarks of high-end living, open flow, private outdoor space, premium materials, and even integrated work-from-home zones.
By prioritising vertical storage, smart zoning, and multi-use features, you can achieve a compact space that lives like a full home. These one-bedroom layouts are especially popular for downsizers, students, or solo renters and offer exceptional ROI when paired with the right inclusions.
