A house can last much longer than the circumstances it was designed around.

Children arrive and leave. Work moves home. Relationships and households change. People recover from injuries. Parents may move in. Mobility changes. What seemed essential at 40 may be unnecessary at 60 and difficult at 80.

We know this. Yet much of the conversation about “future-proofing” housing still involves trying to anticipate these changes and designing solutions for them in advance.

New research into ageing and technology suggests there may be another way of thinking about the problem.

Miguel Gómez Hernández's 2026 doctoral research at Monash University compared the futures imagined for older people by the technology industry with those imagined by older people themselves. His research found a significant difference.

Industry visions tended towards monitoring, automation, health technology and the management of risk. Older people described futures that were more contingent. Technology could be useful, but so could familiar objects, relationships, manual control, repairability and the ability to alter their surroundings themselves.

The distinction matters well beyond technology.

It asks whether designing for an uncertain future should be about deciding more now — or preserving the ability to decide later.

A house that works today is not necessarily a house that will work tomorrow

Australian housing research already shows the difference.

An AHURI study of Australians over 55 found that more than 90 per cent considered their dwelling suitable for their current needs. Only 70 per cent thought it would meet their longer-term aspirations.

That is an interesting gap.

It suggests the problem is not simply a stock of badly functioning houses. A home can work perfectly well for someone's life now and become less suitable as that life changes.

Australia's building regulations have begun responding to part of this problem.

The NCC 2022 livable housing provisions introduce measures including step-free access, wider and more usable circulation, additional bathroom space and reinforcement that allows grabrails to be fitted later.

These are sensible changes precisely because they do not require us to know who will live in the house or exactly what will happen to them.

A reinforced bathroom wall does not assume that someone needs a grabrail today. It makes installing one easier tomorrow.

That small distinction contains a much larger idea.

Designing for change is different from predicting change

There is good evidence that modifying homes can help people remain independent.

A 2025 systematic review examined 20 studies of home modification for older people. Thirteen reported effective outcomes across the measures studied, including fall prevention, functional independence and cost savings. Other research has found benefits from interventions including handrails, bathroom modifications, improved accessibility and occupational-therapist-led modifications.

So the argument is not that we should stop making homes safer or more accessible.

Quite the opposite.

The question is when those decisions need to be made.

Some things are difficult or expensive to change later. Structural arrangements, circulation, stairs, floor levels, service locations and the basic dimensions of rooms can substantially constrain what becomes possible.

Other decisions do not need to be fixed at the beginning.

If architecture can distinguish between the two, a house does not need to contain every possible future solution. It needs to avoid unnecessarily preventing those solutions.

That is a different understanding of future-proofing.

Adaptability can be very ordinary

This does not necessarily mean movable walls, elaborate modular systems or technology throughout the house.

Often the useful decisions are much quieter.

A room with dimensions and access that allow it to serve another purpose later.

A ground-floor space that could become a bedroom without rebuilding half the house.

A bathroom arranged so that additional support can be installed if it becomes necessary.

Services located where they can be reached and changed.

Circulation that does not introduce steps where none are necessary.

Technology that can be replaced without making the building unusable.

A plan that does not depend on every room retaining the function written on today's drawing.

None of these decisions determines what somebody's future should look like.

They simply leave more futures available.

There is another scale to the problem

Ageing in place is often treated as a problem contained within the house.

It isn't.

AHURI's research points to the importance of proximity to family and friends, shops, healthcare, public transport and familiar communities. Other Australian research has similarly found that housing aspirations involve independence, privacy and security as well as the physical characteristics of the dwelling.

A perfectly accessible house in a place where someone can no longer reach the things they need may not support independence particularly well.

That changes the architectural question again.

Designing for a long life is not only about whether someone can move through the bathroom at 80. It is also about whether the house remains connected to a life outside it.

The building and its location cannot really be separated.

Technology complicates the picture

Technology will undoubtedly play a larger role in homes.

Sensors can detect falls. Automated systems can control lighting and temperature. Devices can monitor health. Smart systems can help people with physical limitations do things that might otherwise require assistance.

Those possibilities are real.

But the Monash research is useful because it complicates the assumption that more automation necessarily creates more independence.

Older participants considered questions of trust, privacy, cost, repair and control. They also imagined what happens when technologies stop working, including during disruptions such as bushfires, floods and power failures.

A system intended to increase independence can create a different kind of dependence if basic functions become inaccessible when the system fails.

This is not an argument for analogue houses.

It is an argument for understanding resilience as more than technological capability.

Sometimes a manual override is sophisticated design.

We should also be careful about what the research can tell us

The evidence here is not complete.

The Monash research is qualitative. It helps reveal assumptions and experiences, but its participants cannot represent every older Australian.

Systematic reviews provide stronger evidence that home modifications can improve particular outcomes, but researchers themselves identify gaps around long-term adaptability, personalised interventions and the interaction between housing, technology and changing circumstances.

We therefore cannot point to a particular floor plan and declare it the scientifically proven adaptable house.

Nor should we.

That would reproduce the problem.

People's lives differ. Their needs change differently. Their financial circumstances, families, abilities, preferences and homes are different.

Architecture cannot eliminate that uncertainty.

It can respond to it.

Perhaps we have been asking the wrong question

“Will this house meet your future needs?” sounds sensible.

But answering it requires knowledge neither the architect nor the client possesses.

There may be a better question:

If your needs change, how difficult will this house be to change with them?

That shifts the task from prediction to possibility.

Some decisions made today should last for decades. Others should be allowed to change. Good design requires knowing the difference.

A house does not need to anticipate every version of the life that might happen within it.

It needs to leave enough room for those lives to unfold.

Editorial note
This piece turns ageing-in-place research into a question relevant to anyone designing or renovating a home: which decisions genuinely need to be fixed now, and which should preserve the ability to choose later? Its value is practical rather than ideological. It gives readers a better question to use when making long-term design decisions.
