Economic value of universal housing design

Front cover of the report showing an older grey-haired couple sitting together smiling. Title is exploring the economic value in housing built to universal design principles.Consumers buy things that they want and need now rather than purchasing things with the future in mind. Well, that makes sense. For everyday items this poses no problems. But for expensive, longer lasting items, such as a home, it can be a problem. Many older Australians live in a home that was purchased in mid life. It was suitable then. But now that cherished home is challenging their independence in older age. That’s why all homes should have universal design features.

A new report based on a survey of care-givers, both paid and unpaid, provides insights into their experiences and observations on the impact of home design on their caring role. The researchers found that housing design features and proximity to amenities had a value that extended beyond those of residents. That is, it facilitates community capacity and social engagement, physical wellbeing and ease of providing care services. 

The executive summary concludes with a statement that supports universal design in housing for people to age well:

“The public value implicit in universally designed housing is conceptually demonstrated by associated increases in ageing well outcomes and reduction in the need for, the level of, and the time spent on, care to support positive ageing outcomes (ie. generating efficiency gains in achieving ageing well outcomes).

The key findings of the study 

    • Universal design features impact on the level of care needed to support ageing well.
    • The location of the home and access to amenities also has an impact on the level of care needed.
    • The time needed to support people with basic living activities is reduced.

The title of the report is, Exploring the economic value embedded in housing built to universal design principles: Bridging the gap between public placemaking and private residential housing.

The study was undertaken by RMIT University and the Longevity Group Australia.

From the abstract:

We explore the public value implicit in housing incorporating universal design principles. Value is conceptually demonstrated by identifying housing design and location attributes, associated with increases in ageing well outcomes via the reduction in the time spent on caring duties.

A survey captured the experiential knowledge of in-home care service providers and their observations of the impact of the home on the ageing well outcomes. 

We found that certain housing design and location features have value that extends beyond that experienced solely by its residents. It also facilitates community capacity and social engagement, physical wellbeing and ease of delivery of public services such as care support.  

Sea Change or Urban Uplift?

long view of a Perth city mall with shops and cafes under awnings and trees for shade. Tall buildings are in the backgroundWhile some retirees will seek a sea change to resort-style living, others want to stay connected to their families and established neighbourhoods. Some might even be thinking about planning renovations to make staying put easier. A place in the country sounds ideal, but is it the right choice?

An article in Aged Care Insite critiques the age-restricted model of villages. It asks if this is a sustainable model into the future. The article was written in 2018 and shows foresight given today’s issues with aged care. Many of the current issues are discussed and the author, Susan Mathews questions if this is the right way forward. 

Mathews proposes alternatives, one of which is flexibility of design across the housing market so that people can receive care at home when it is needed. This fits with the principles of universal design as outlined in the Livable Housing Design Guidelines at Gold level. Other key points are inter-generational interaction, connectivity, inclusion, and proximity to conveniences. A good article  from an architect’s perspective. The title of the article is Aged Care in the urban context: what’s missing?  

Autism friendly home environment

Picture of a large family looking jubilant outside their houseFamilies living with autism have lots of stories to tell. Some of these stories were captured by researchers. The aim was to find supportive home features to make homes more autism-friendly. 

A study by Wasan Nagib and Allison Williams uses family stories to explore the challenges they face. The authors of  “Toward an autism friendly home environment” conclude with three recommended home typologies – detached and attached houses, and apartments. They also discuss policy implications. The article was published in Housing Studies, by Taylor and Frances Online. You can access a free read of the article via ResearchGate.

Abstract:

This study explores the challenges faced by children with autism and their families in the home environment and how physical elements of the home environment can be designed or modified to alleviate these challenges and create an autism-friendly home.

The research employs qualitative methods to learn from the experiences of key informants involved in creating or modifying the home environment of people with autism; this involved interviews with architects and occupational therapists. To learn from the families themselves, an online survey of the families of children with autism across Canada and the United States was conducted.

The study provides insight into the physical, social, and psychological challenges affecting the quality of life of children with autism and their families in their home environment and the contribution of home modifications to alleviating the challenges.

The appropriateness of the three housing typologies – detached houses, attached houses, and apartments – to accommodate autism-related needs is discussed together with potential policy implications.

Reasons for universal design in housing

Graphic with orange and red buildings depicting several sizes of home from small house to apartment block. There are good reasons for universal design in housing.The idea of universal design in housing is not new. Despite academic research proving the need, and practice guidelines based on real lives, we are still a long way from achieving access for everyone at home. Here are some resources with reasons for universal design in housing.

An architectural view of aged care

Apartments in shades of grey are linked by a graded pathway to provide accessibility.The Longevity Revolution along with the recent pandemic is asking questions about aged care and retirement living. Can we keep doing the same? The short answer is no, but what to do instead?

A report from an architectural group reviews the literature and makes some strategic suggestions for the future. The research looked at how the market can re-align itself to the aspirations of upcoming ageing generations. As we know from previous research, it isn’t looking like retirement villages, and there’s a preference for aged care at home. 

The costs of aged care are discussed at length. Consequently, affordable strategies are needed for both older people and for government.  

Using models from overseas they suggest serviced apartments, communal flats and co-housing. Multi-generational living is presented as a new idea. It is premised on the notion that people will be happy to move when their current home no longer suits. We already have multi-generational living in our existing neighbourhoods. The homes just aren’t accessible for everyone at every age. Nevertheless, the researchers eschew the notion of mandatory universal design standards in dwellings. 

The report returns to the notion of specialised housing products for older people and talks of being able to convert “normal dwellings” to enable home care. The multi-generational neighbourhood model is presented as a combination of different housing options where young and old exchange services.

The title of the report is Aged Care in Australia and argues for the market to create new and sustainable ideas. It was prepared by Architectural Research Consultancy for Carabott Holt Architects.

Editor’s note: Researchers claim the Productivity Commission supports voluntary uptake of universal design standards, not regulation (see p.4). Nevertheless, the Productivity Commission recognises, “The Australian Government should develop building design standards for residential housing that meet the access and mobility needs of older people.” (See the Summary of Proposals.) The PC report goes back to 2011 when Livable Housing Australia was set up to lead a voluntary roll out of UD features in housing. As we know, this has not worked.

Future proofing existing social housing: A case study

A group of red brick three storey apartments shaded by trees. What about a post-pandemic social housing stimulus project? Not a new idea, but such ideas usually relate to new housing. So what about modifying existing social housing? This is so that people can stay in their community for longer as they age. Lisa King argues the case in a research paper with a focus on older women. 

King’s paper begins with a literature review of the issues related to older women and housing. The case study takes the floor plans of existing dwellings and makes changes to show how to make them more accessible. The case study includes studio units and two bedroom units. There is also a site plan, a demolition plan and costings too. 

King summarises the research by giving a rationale for choosing 1960s dwellings, and says the project is scaleable, modular and cost effective.  In addition, this type of work provides employment for small and medium businesses. And of course, it optimises existing stock while improving the lives of residents. King sums up with, “The result would be universally accessible housing and an asset which would assist meet the growing demand for residents to age-in-place with dignity.”

A thoughtful and nicely written paper and well referenced. Although the focus is on older women, the concepts apply across all social housing. The title of the paper is, Future-proofing Existing Social Housing: A case study helping meet older women’s housing needs.  

For a short read King’s paper was featured in a Domain article, Trapped inside: Why social housing apartments need an urgent revamp.  

Housing, Health and Accessibility

Multi coloured graphic depicting the key elements in the guidelines "How housing can improve health and well-being".There are five key areas for healthy housing and accessibility is one of them. The WHO guidelines on housing and health and accessibility takes into consideration ageing populations and people with functional impairments. It recommends an “adequate proportion of housing stock should be accessible.

In the remarks section it argues that living in an accessible home improves both independence and health outcomes. Although the guidelines argue for only a proportion of housing stock, it has put the issue on the agenda. It shows it is as important as all other factors. However, the notion of proportion can lead some agencies to think that means specialised and segregated housing. 

The other key areas are crowding, indoor cold, indoor heat, and home safety. For more detail there is an additional document showing method and results of the systematic review that underpinned this section of the Guidelines – Web Annex F. and includes interventions such as home modifications and assistive technology. 

The Healthy Home

View of the website landing page for Healthy Home Guide.Joining the dots between all aspects of physical and social sustainability is important for a healthy life and a healthy planet. Central to this is the design of our homes. The Healthy Housing Design Guide from New Zealand says they need to be durable, efficient in size and cost, and friendly to the occupants and the environment.

The three bar menu icon on the landing page of this online resource takes you to the content of the Guide. Universal Design leads in the table of contents. This is pleasing as most other guides leave it to a last thought at the end. The design detail features wheelchair users for circulation spaces, which, of course are good for everyone. Among the interesting images is a lower storage draw doubling as a step for child to reach the kitchen bench. The case studies focus on energy efficiency and sustainability.

This is a comprehensive document beginning with universal design, site and location, through to air quality and acoustics and ending with certifications. The Guide characterises a healthy home by the acronym HEROES:

      • Healthy: 
      • Efficient: 
      • Resilient: 
      • On purpose:  
      • Environmental: 
      • Sustainable:

The style of the website is pleasing but the landing page gives little idea to navigation. It says “Welcome” and then asks visitors to stay super involved. There is a bar with an arrow to go to the Foreword. The navigation is via the three bar menu icon at the top left of the page. 

The video from the launch of the guide takes you through the content. Universal Design gets a mention at the 25 minute mark. It is introduced by Henry McTavish.

Tomorrow’s Homes: A sustainability perspective

Tomorrows Homes front coverUniversal design in housing faces the same policy and industry challenges as the sustainability movement. Consumers are unclear about their choice, and confused by terminology and rating systems. Home builders are locked into supply chains that limit innovation, and financial institutions can’t see the value of such designs. 

The Australian Sustainable Built Environment Council (ASBEC) has devised a policy framework for transitioning to sustainable homes. It identifies five key actions:

    1. National leadership
    2. Benchmarking and upskilling
    3. Building a foundation of leading homes
    4. Engaging consumers
    5. Leveraging finance

Tomorrow’s homes: A policy framework outlines how the structure of the housing industry creates restrictions on doing anything differently. It also has suggestions for appealing to consumers by using language they relate to. Comfortable, healthy, affordable, easy to use – in short, appealing to their aspirations. Consumers don’t frame their aspirations in words such as sustainable, accessible, or universal design. And they don’t aspire to ageing or disability.

Inclusion and efficiency in home renovations

logo-uhasselt_0_0

The concept of comfort can be used to join the dots between inclusive design and energy efficiency. This is the suggestion from Hasselt University in Belgium. The authors conclude in Merging Inclusive Design and Energy Efficiency as a disruptive approach to housing renovation that:

“When the concept of comfort is expanded to include the a full range of spatial, usability, and cognitive aspects, the merging of ID and EE can offer inhabitants a more complete sense of comfort, and by doing so increasing adoption of both types of measures, in line with wider governmental and societal goals.”

Abstract. There is a pressing need for housing renovations that both accommodate lifelong living and significantly increase energy efficiency. Much research has been done on both Inclusive design (ID), particularly in the context of accessibility, and energy efficiency (EE). However, they are treated independently and faced with limited adoption. A simultaneous renovation for ID and EE might lead to renovation concepts that better fulfil the residents’ desire for comfort in addition to savings in money and time. Comfort is an important driver for both types of renovations. As a result when the concept of comfort is expanded to include also spatial/usability, social, cognitive and cultural aspects, the merging of ID and EE can offer residents a more complete sense of comfort, thereby increasing the adoption of both ID and EE.

 

Housing multigenerational households in Australia

House half built showing timber frameworkThe top five reasons for multigenerational living are financial, care arrangements and support, adult children yet to leave, starting or continuing education, and older (grand)parents moving in. The reasons behind the trend towards multigenerational living are not quite as simple as the list implies.

Cultural factors are also part of the story. Home ownership of a detached dwelling is critical to successful multigenerational living. There is usually greater flexibility to modify and adapt the home as needs change, which is not possible in apartments or rental properties.

These are the findings in a book chapter by Edgar Lui, Hazel Easthope, Bruce Judd and Ian Burnley. They end the chapter by discussing policy implications and include the need to adopt universal design principles in all new properties and major refurbishments. They add that although these principles have been around for more than 50 years they are yet to materialise in home designs as voluntary codes  which are unlikely to be agents of change.

The title of the chapter is “Housing Multigenerational Households in Australian Cities: Evidence from Sydney and Brisbane at the Turn of the 21st Century.” 

The title of the book is, Housing in 21st-Century Australia: People, Practices and Policies.

Introduction

“Over the last two decades new and significant demographic, economic, social and environmental changes and challenges have shaped the production and consumption of housing in Australia and the policy settings that attempt to guide these processes. These changes and challenges, as outlined in this book, are many and varied.

While these issues are new they raise timeless questions around affordability, access, density, quantity, type and location of housing needed in Australian towns and cities. The studies presented in this text also provide a unique insight into a range of housing production, consumption and policy issues that, while based in Australia, have implications that go beyond this national context.

For instance how do suburban-based societies adjust to the realities of aging populations, anthropogenic climate change and the significant implications such change has for housing? How has policy been translated and assembled in specific national contexts?

Similarly, what are the significantly different policy settings the production and consumption of housing in a post-Global Financial Crisis period require? Framed in this way this book accounts for and responds to some of the key housing issues of the 21st century.”

Tick of approval for Visitable Housing

A woman is pushing a stroller in the front door and you can also see a nice wide hallway.The terms “visitable housing” and “visitability” are essentially about people who use mobility aids having the same rights to visit friends and family in their homes. It doesn’t necessarily mean they can live there or stay overnight. The three key features associated with visitability are a step free entrance, wider doorways and a usable toilet on the entry level. Part M of the UK building code reflect these features. 

Visitability differs from full accessibility and universal design. It was devised as a minimal baseline to entice the property industry to get on board with the ideas. Although the concept has been around for twenty years, it has gained little, if any, traction. Visitability is not a concept easy to sell unless the buyer thinks they need it. And few do. 

Perceived value of visitable housing

A research project carried out in Ohio in 2015 looked at: home-buyers’ perceived value and perceptions of visitable features; developer, designer and builder perspectives; real estate agent views; estimated costs; and which house buyers were most likely to buy. The aim of the report was to create a persuasive argument for adopting visitability in new homes in Ohio. However, the researchers acknowledge industry resistance and suggest incentives to encourage uptake, or mandating the features.

The report is structured into three sections based on their surveys of homeowners and home buyers, industry stakeholders, and real estate agents. All groups were asked to assess photos of visitable features in homes. In all instances, participants believed the homes would sell for more and sell more quickly. Industry stakeholders estimated the features would cost less than one per cent of construction costs. This is in line with other research.

The title of the report is, Perceived value of visitable housing in Ohio. It is also available through Academia.edu

Elements of the research are available in their paper, Homeowner and homebuyer impressions of visitable features.  

In Australia minimal access features are now in the National Construction Code in the form of the Livable Housing Design Standard. States and territories are adopting the Standard into their respective building codes at different dates in 2024 and 2025. Queensland adopted the Standard in 2023.

Accessible Housing: what’s it worth?

Three stacks of coins sit alongside a wooden cut-out of a house shape.Home builders argue that people won’t pay extra for universal design features. The assumption of extra cost aside, they are also assuming that people wouldn’t pay more. But would they? A study from Europe asked just that question and the answers are surprising. Renting is the norm in many European countries and so it is difficult to compare with owning. However, finding out how much extra rent people are prepared to pay gives us some indication.

A survey of renters in Germany and Slovakia found that 40 per cent would pay an extra 10% more, and 40 per cent would pay up to 20% more for a more accessible dwelling. Only 12% said they would not pay more. And the age of the respondents wasn’t a factor in the findings. The survey covered many other aspects of home living, and the findings are detailed in the article. There’s lots to take away from this study – the willingness to pay more for an adaptable or accessible dwelling is just one factor.

Editor’s Note: Another way to measure the worth of universal design in housing is to ask, “How much would you pay to stay home and not go to aged care – what would that be worth?”

Abstract: The role of this study was to determine which changes people think they need to make in their home in response to getting older. At an advanced age, the likelihood of different limitations, such as vision impairment, hearing impairment, or physical inability, are increased. At present, when faced with such limitations, tenants are often forced to leave their long-term living spaces, as these spaces cannot serve their “new” individual needs. This transition from the privacy of their home to a new environment is often a painful change. They must leave a well-known environment, as their homes cannot be adapted to their new needs. The aim of this paper is to develop a comprehensive approach for the design of an exterior and interior space which can serve people through all stages of life, particularly in terms of mobility. This means that, even if an unexpected situation incurs changes in an individual’s movement abilities or physiological limitations not only by natural aging, but also according to accidents or disabilities their living space can be adapted to the given conditions. The results of a survey conducted in Germany and Slovakia are presented. In the survey, respondents expressed their opinion on what they considered important in creating an adaptive environment, considering various life changes. Based on the results of the survey, studies of possible modifications of flats and houses are developed. These results are analyzed in terms of three age groups: people aged below 35, those aged 35–50, and those aged over 50. People under 35 are considered to be quite young, with different views on life and on the environment. Their priorities typically differ from those of people around 50. People aged 50 more; have been under medical treatment for a consistent amount of time. This group of people is still active; however, they experience different design requirements for their potential home.
