Good Design: How do you measure it?

Logo of the Urban Design Conference.Good design means different things to different people, so how can you measure or evaluate it? As Trivess Moore says, “Poor design – an absence of ‘good’ design – locks in owners, the local community and cities to substandard urban environments, often for considerable time periods.” Moore believes that arguments for the value of good design are too easily dismissed because we lack a rigorous evidence base. Maybe this is one of the reasons the principles of universal design and notions of public good are ignored. An interesting argument in this paper to which the principles of universal design could be added. While written in 2014, it has relevance to the upcoming RIS on Accessible Housing.

The paper was published in 7th International Urban Design Conference 2014 and is titled, Valuing form and function: Perspectives from practitioners about the costs and benefits of good apartment design. It’s on page 73.

Abstract: Methods for placing values on good design are under-researched in Australia. Without a rigorous evidence base, costs are anticipated and benefits unrecognised. This paper presents an overview of the current state of the value of good design research for the built environment, and reports upon a series of interviews with experienced building industry stakeholders in Australia and the UK. The research finds that while the benefits of good design are recognised by building practitioners, these are not being consistently translated into exchange value and are therefore not being picked up in mainstreaming best practice. In order to raise the quality of design there is a need to develop ways to measure and articulate these benefits to housing producers and consumers.

Better home design reduces care hours

A bathroom has been stripped out and a few builders tools lay about on the floor. The bath is laying on its side. So why don’t we design homes for longevity in the first place? These findings are from a study by Phillippa Carnemolla, and there is more to this story. People felt more independent and enjoyed improved quality of life. This had a positive impact on their general health as well. There is more to discover in Carnemolla’s paper and it supports the need for all new homes to have basic access features included.

The title of the paper is, How Home Modifications Impact Ageing Well at Home: Supporting a Lasting Housing Legacy. It was published in Proceedings of the 5th International Conference for Universal Design in Fukushima & Tokyo 2014. Hence the reference in the Abstract to the upcoming 2020 Tokyo Games.

The International Journal of Environmental Research and Public Health published an update in 2019. The Title is, Housing Design and Community Care: How Home Modifications Reduce Care Needs of Older People and People with Disability

Here is Phillippa’s Three Minute Thesis video giving the bottom line.

Abstract

A lasting legacy of all Olympic and Commonwealth games is their athletes villages. This paper discusses the potential for home modifications to support the process of ageing well that builds on this housing legacy and as such points to the benefits to be gained from both wider uptake of universal design in housing plus attention to special adaptations as needed.

In the context of Australia’s ageing population, ageing well can encompass a number of different housing and care models, however common to all of these is a drive to maintain quality of life levels.

There is evidence to suggest that home modifications impact recipients in a number of overlapping ways, by increasing independence within the home, increasing social participation and enabling people to remain in their own homes for longer as they age.

This paper refers to completed stage one findings (Levels 1, 2 and 3) of an ongoing research project investigating the value of home modifications. It uses a mixed method approach and thematic analysis of survey responses from home modification recipients (n=157). This research design enables the measurement of the impact of home modifications to housing and resulting changes to care giving needs.

The survey results reveal a decrease in reported care hours needed following home modifications, a trend which is further supported by the thematic analysis. In conclusion, the research contributes to developing evidence that home modifications can have a measurable impact on the care needs of recipients and support the changing social needs of ageing populations in ageing well.

Joining the dots for ageing in place

A chart shows the four main features of Lifelong homes: Safety, Walkable community, Visitability, and Affordability.A research paper from Colorado State University brings together all the elements for successful ageing in place – universal design in housing, walkable and wheelable communities and a discussion on home and place, and what it means for residents. It shows how simply providing infrastructure is insufficient to support population ageing.

While the situation is a little different in the US, the research supports Australian studies and the advocacy for universal design in housing. However, the recommendation for market incentives in terms of certification has not worked in Australia, save for the specialised homes specifically for people with disability. It is a similar situation in New Zealand. It has not produced mainstream uptake of accessible housing.

The tile of the report is, Colorado Lifelong Homes: A review of barriers and solutions for aging in place. 

Abstract:

Colorado’s aging population is growing, yet our housing options are not evolving to support this population. The need for housing that accommodates older adults as they age is crucial to balancing demands on other services, such as assisted living facilities, and to support successful and healthy aging.

Most homes in our state are not built using principles of universal design that support successful aging in place. The outcomes of community and industry engagement activities show that advocating for lifelong housing is a critical step to help advance age-friendly housing in the state of Colorado.

This paper summarizes key research and industry trends related to lifelong homes, the barriers in the marketplace, and the key qualities of lifelong homes. Based on this research, we present a path forward for advancing affordable, healthy, and safe home options for our growing population of older adults in Colorado and beyond.

 

The 100 year life

A graphic showing facades of different styles of free standing homes in lots of colours. They look like toy houses.People expect to grow old, but they don’t plan to grow old. Public policy has to do more than just capture people when they can no longer care for themselves. Even if people plan for their older age, there are policy and built barriers preventing the continuation of a “decent life”. And housing is a key barrier.

The report, The 100-year life: the role of housing, planning and design, highlights the issues and provides recommendations. The report recommends an integrated approach to housing, planning and design to support people in later life. It stresses the importance of taking a universal design approach and co-production. Developers, planners and local authorities also have an important role to play. And of course, focusing on older people means that people of all ages are included. While this is a UK project, there are many aspects that apply to other countries including Australia.

The research was conducted jointly by Design Council, Centre for Ageing Better and Social Care Institute for Excellence. The report in PDF was published in June 2018. The report includes references and resources.

Housing Diversity Now Urgent

A row of flat front row homes in blue and white.Roberta Ryan writes in The Conversation that vested interests are continuing business as usual without reference to demographic and lifestyle changes within the population. They are actively resisting change and arguing against policies to deliver more diverse housing types. Ryan argues that governments need to challenge vested interests that want to keep the status quo. The title of the article is, People want and need more housing choice. It’s about time governments stood up to deliver it. While this article doesn’t mention universal design or accessibility, it is inherent in the argument that governments need to challenge, on all fronts, vested interests that lobby for the status quo to remain.

Ryan writes, ‘Indeed, three recent surveys showed city dwellers are looking for housing diversity, particularly smaller houses such as terraces and semi-detached dwellings, in inner and middle suburbs. This demand comes from downsizers as well as families. We are seeing a clear recognition of the shortage of this stock.

Raising the bar on housing standards

Front cover of the report which calls for improved housing standards for accessibility. Advocates in several countries have been lobbying for mandatory accessible housing standards for many years. At last Habinteg in the UK has succeeded in getting the topic on the government’s agenda

A forecast for accessible homes, is an important report covering all the key issues, ending with three key actions. The Habinteg report reveals a “huge postcode lottery in the planned supply of new accessible homes…”.  Therefore it is crucial to “set a national policy that will create a level playing field and more certainty for developers”.

The report found that existing basic minimum standards as set out in Part M1 of the building code are insufficient. The planned development of accessible housing is set to fall short of previous official predictions. The report also has personal case studies to highlight the impact the lack of availability has on their lives. Mandatory standards within building regulations are needed because Part M1 is too basic. The shortage of housing with liveable access features, which are suitable for everyone, is now at a critical level.

Is there a market for accessible homes?

Front cover of Habinteg report showing coins and Monopoly houses. Hidden market for accessible homes.The Habinteg site has articles that discuss the market appeal of Lifetime Homes in the UK context. There are some interesting research reports by the London School of Economics, Ipsos MORI, and Habinteg Housing and Papworth Trust. UK homes are traditionally two storey with the bathroom and toilet upstairs. They are generally smaller than Australian homes too, which makes it more difficult in terms of circulation spaces.

It was thought that Part M of the building code would create greater accessibility in homes, but it hasn’t helped much at all. The best part is that it requires a downstairs toilet, which is handy for everyone. Aitken explains his own research project on this topic looking at homebuyers and estate agents. The blog site has attracted several good comments and are worth reading too. By the way, it seems stair lifts are not that popular with purchasers. 

Apartment design audit without UD

Three shiny blue apartment towers rise into the sky.Health and wellbeing is the focus of an audit report of Australian state and territory apartment design guidelines. There is a passing mention about universal design and residential mobility at the end. These are considered indirect factors for wellbeing that might be worth researching at another time. There is a comparison chart of the similarities and differences between state and territory policies and guidelines. Many of these include universal design and accessibility, but these factors were not picked up in the comparison chart. The nationally recognised Livable Housing Design Guidelines were not referenced even though they also support health and wellbeing. This is an open access report and should be of interest to anyone in the residential housing sector. It is good to see there is a focus on quality of design.

The title of the paper is, The high life: A policy audit of apartment design guidelines and their potential to promote residents’ health and wellbeing

From the conclusions: “Finally, this audit focused on specific design themes known to impact health, however other design features also contribute to the experience of apartment living (e.g., storage, car/bike parking, lighting, universal design). While these features might not directly impact on health and wellbeing, they nonetheless contribute to the ease of long-term apartment living, and many policies include standards for such features. Given the evidence that apartment and neighbourhood satisfaction can reduce residential mobility and enhance mental health (Giles-Corti et al., 2012), these indirect factors may be worthy of investigation in future studies.”

Editor’s Comment: Given we have population ageing and housing demands by people who are NOT on the NDIS, I should have thought universal design and accessibility are essential to health and wellbeing. There is nothing healthy about not being able to get out of your home or being able to visit your family. The building code requires disability access into apartment buildings and public space, but not inside the dwellings – which is where universal design comes into play.

Caroma designs with people

Two researchers are creating the walls for a bathroom in the university lab.Caroma – the bathroom people, and University of New South Wales got together to do some hands-on research on bathroom fittings with  a group of older people. The resulting report covers the collaborative research methods as well as the attitudes and feelings of older people towards assistive fittings and designs. The title of the Caroma report is Ageing Joyfully

Older people feel stigmatised by “special” designs. Some fittings, such as a small grab rail, could be included as standard in all bathrooms therefore avoiding the stigma. Then we would have safer bathrooms for all (universal design). 

Here is a quote from the report that shows how stigma prevents some people from adapting their homes: “One member of a co-design group remembered the time her husband was prescribed grab rails “The shudders went through, it has come to this!” However, after having the rails for a long time she found herself using them more and more, said she wouldn’t be without them and thought they would benefit everyone. ‘If it were standard it would be normal’ and so would have no stigma of being associated only with the frail elderly.”

The report offers advice for designers, “For designers, working collaboratively with older people provides a rapid feedback on assumptions and design proposals. Older people have at least as varied aesthetic preferences as any other cohort, and they have a powerful connection between home and identity.”

Front cover of Caroma Ageing Joyfully ReportEditor’s note: It is a pity the front cover picture is a stock item showing a young person in a carer uniform semi-embracing an older woman in a wheelchair. As we know, this is not indicative of the breadth of the older population. It was probably chosen by the designer contracted to layout the document.

 

Economic arguments for universal design in housing

A line of complex manufacturing machinery used to show the complex process and number of stakeholders involved in mass market housing.The 2022 National Construction Code has at last included the Livable Housing Design Standard. Citizen advocacy and political will made this happen. But there were strong economic arguments. Research papers have produced solid economic arguments for universal design in housing over many years. However, these arguments failed in their quest. So the issues are beyond those of economics. For those who want the research, here is a list of papers, including the cost effectiveness of home modifications (or not needing them in the first place). 

Selected articles on economic arguments

The cost of NOT including accessibility in new homes This landmark article by Smith, Rayer and Smith (2008) uses complex economic methodologies to show that a new home built today has a 60% likelihood of having an occupant with a permanent disability. People with disability live in families – not alone – which is often forgotten. They followed up this work in 2011 with similar results.

Housing, older people and resilience

An old weatherboard farm building sits in front of a tall dark brooding mountain.People want to stay put as they age. That means housing design is critical in supporting this desire, as well as ageing-in-place policies. A new study from New Zealand looked at issues of appropriate housing for older people, and how people and communities can develop resilience to adverse natural events. The findings relate to ageing societies across the globe and within the context of changing environmental conditions. The decision tools that researchers devised from this participatory research are useful for older people and for architects and other designers. 

The title of the article by Bev James and Kay Saville-Smith is “Designing housing decision-support tools for resilient older people“. There are several useful references at the end of this excellent study. 

ABSTRACT: Our ageing populations make it critical that older people continue to live and participate in their communities. ‘Ageing in place’, rather than in residential care, is desired by older people themselves and promoted as policy in many countries. Its success, both as policy and practice, depends on housing. House performance, resilience, functionality and adaptability are all essential to maintaining independence. Three New Zealand research programmes have worked with older people to investigate issues around housing, ‘ageing in place’ and how older people and communities can become resilient to adverse natural events. Using participatory research techniques, those programmes have generated evidence-based decision-support tools to help older people maintain independence. These tools have been co-designed and widely tested with older people and others. Designed to help older people identify priorities and information requirements, assess diverse factors determining thermal performance and dwelling resilience as well as repairs and maintenance needs, the tools help improve decisions around: repairs and maintenance assessment and solutions; dwelling and location choices and housing options. Various organizations have adopted the tools. This work demonstrates how research outputs can be used to facilitate older people’s housing choices while also giving architects and designers guides for meeting older people’s housing needs.
