When a parent is diagnosed with dementia, one of the first things adult children start thinking about is where they should live. Residential aged care is one option. Living in the main house is another. But for many Melbourne families, there is a third path that is increasingly popular and — for the right situation — significantly better for everyone involved: building a G-Flat™ in the backyard.
A properly designed granny flat dementia design Melbourne build keeps your parent close — within eyesight, within earshot, within a 30-second walk — while giving them a space that is entirely their own. It preserves their dignity and independence in a way that moving into the main bedroom simply cannot.
Why a Granny Flat Works Well for Dementia Care
Familiar, consistent environment. People living with dementia benefit enormously from environmental consistency. A secondary dwelling designed from the start for their needs — with a layout they can learn, fixtures in predictable positions and a space that does not change — supports orientation and reduces confusion.
Physical separation with emotional closeness. A backyard G-Flat™ provides physical separation — a private front door, a separate living space — while keeping the family within immediate reach if something goes wrong.
Reduced caregiver burnout. A secondary dwelling gives caregiving family members a genuine boundary: they can be present and involved without being constantly on duty.
The Design Features That Matter Most
Single-level, step-free living
All Innovista G-Flat™ builds are single-storey, which eliminates staircases as a hazard. Step-free access means no threshold lips between rooms, no raised shower trays and no steps between the interior and the decking or outdoor area.
Victoria’s 2026 Livable Housing Silver Standard, which now applies to new secondary dwellings, mandates flush entry, wider doorways and step-free shower access as minimum standards. Every new G-Flat™ build meets these requirements as standard.
A simple, consistent floor plan
The Lana 2 G-Flat™ is particularly well-suited to dementia care. Its layout places both bedrooms and both bathrooms in a straightforward arrangement, with the living and kitchen area opening to the front. The dual-bathroom configuration — Bathroom 1 positioned directly adjacent to Bedroom 1 — is especially practical for a parent who needs reliable, close bathroom access through the night.
Bathroom accessibility
The Luxe G-Flat™ includes underfloor heating in the bathroom — a feature with real practical value for older adults who are more sensitive to cold. The frameless walk-in shower in the Luxe finish removes the shower frame as a trip hazard and makes wet-area access easier for a person with mobility challenges. The floating toilet and in-wall cistern allow for easier grab rail installation.
Heating and cooling
The Luxe G-Flat™ includes a multi-head split system to the living area and both bedrooms — providing independent heating and cooling control across all habitable rooms. For dementia care, consistent temperature control throughout the dwelling is important.
You can see the full inclusions and specifications for the Lana 2 and each finish level on our G-Flat™ page.
Positioning the G-Flat™ on Your Block
Visibility from the main house. Position the secondary dwelling so the main house has a clear sightline to the G-Flat™ entry.
Short, direct path between the two dwellings. The path from the main house to the G-Flat™ should be short, well-lit and easy to navigate — ideally a straight, level path with no steps.
Your setback requirements will define the available positions on your specific block.
Insuring a G-Flat™ Used for Family Care
A G-Flat™ occupied by a family member is typically covered under the standard home building insurance policy for the primary property, provided the insurer is notified. You can read more about insuring your G-Flat™ correctly to make sure the structure is protected from day one.
