Toilet design for Western and Muslim cultures

Western toilets are designed for sitting. But this is not the preference for all cultures. Squat toilets are widely used in Asia and are considered better for a healthy bowel system. However, they are not great for Westerners and people with physical disability. Water for cleansing is rarely used in Western countries, but it’s considered more hygienic than paper. So, can universal design solve the differences in toilet design for Western and Muslim cultures? 

Zul Othmann wanted to find a toilet design solution workable for both cultures. The first step was to recruit Muslim families that had adapted their home toilet. Seven families participated as case studies. The experiences ranged from happily using a Western style toilet, to making adaptations to an existing toilet. In some cases both water and paper are used. Some families have adjusted to Western toilets, but visits by family members and friends also need to be considered. 

Design recommendations

The article discusses the family experiences and concludes with some recommendations for designers. Products such as bidets and shattafs are available in Australia, but their installation needs some preparation. 

Toilet converters or squat/step stool for Western sitting toilets need stronger toilet seats for safety. Wall mounted toilets might need additional supports to take the additional weight.

Careful consideration for drainage systems is the main concern. A stand-alone toilet closet in a typical Australian home does not have a floor trap. So finding ways to keep the floor dry when using the shattaf is essential. The paper needs protection from the water if using the toilet in both modes.

Othmann closes the article with comments about vaastu shastra and feng shui. Some designs need to be reversed or mirrored because both teachings originate in the Northern Hemisphere.

The title of the article is, Towards more culturally inclusive domestic toilet facilities in Australia. It provides yet another aspect of inclusion and universal design and the family experiences make interesting reading. Photographs and diagrams highlight key points.

Toilets and tourism

Logo for Universal Design ConferenceToilets are not the same the world over, but they all need to be accessible  as Alaa Bashti points out in her conference poster presentation: “Accessible public toilets and restrooms from an Islamic perspective”.

Alaa Bashti poster presentation PDF

From the abstract:  

The tourism industry has become the most successful service sector, one of its leading job-creators and foreign exchange-earners. Behind this success lies a fascinating understanding of people needs taking into consideration the variety of people abilities and religions. One such group of people who have special requirements when it comes to using restrooms are Muslims, who make up 1.5 billion, or one quarter, of the world’s population.

In Malaysia and most Islamic countries, it is important to understand the ‘Islamic toilet manner’ as it can have direct implications for the design and planning of toilet facilities as Islam advocates for matters of cleanliness. Among the most crucial problems to be solved is whether one is sure to find a toilet one can comfortably use outside of home. 

This paper highlights what might be ideal standards for toilet provision, toilet design according to the Islamic principles and emphasising the importance of public toilets in creating accessible cities for everyone. In designing a public toilet, some elements should be stressed particularly on the understanding of users’ needs.

There is a need for a universal design of a public toilet that is always clean, comfortable and safe as well as relaxing. The Department of Standard Malaysia (SIRIM) has initiated the publication of Malaysian Standards as guidelines for designers; architects, city planners, landscape architects, interior designers, and others who are involved in the construction of the built environment with universal design. Four standards on public toilets are to be developed.

 

What an accessible home looks like

Good examples of universal design are difficult to find. Because universal design is invisible until pointed out, home viewers might not spot it either. Thanks to Taylor’d Distinction Building Design, here are some pictures to show what an accessible home looks like.

Looking forward to the day when there is no need to have a separate section for “accessible housing”. It should be considered mainstream. After all, how many of us can invite a wheelchair basketballer into our home? See more posts on the quest for mainstream universally designed housing

Basic access features are now in the 2022 National Construction Code. However, we are still waiting for states and territories to adopt the Livable Housing Standard. Queensland will lead off in October 2023.

Universal design in the kitchen

The Center for Real Life Design at Virginia Tech renovated two kitchens to incorporate many universal design features. One was designed for a multi-generational family, including an older grandparent and a child with autism spectrum disorder. The other was planned as a multifamily kitchen. These examples show how to do universal design in the kitchen.

The Center’s webpage has an article that explains the design features, and several pictures illustrate the outcomes. The first part of the article is about the Centre, and the second part has detailed explanations.

Julia Beamish also published an academic article on this project that can be accessed from Ingenta Connect: Real Life Design: A Case Study in Universal Design. You can also access on ResearchGate and ask for a copy.

A related article by Sandra Hartje, also available through Ingenta Connect, is Universal Design Improves the Quality of Life for Individuals, Families and Communities. It’s about why it is important for families and communities to design universally rather than how to design.  

Kitchen lighting

A modern kitchen with a bowl of fruit in the foreground and a stove and microwave in the backgroundLighting is of particular importance to anyone with low vision. And people who wear glasses also need good light to see what they are doing. And more light isn’t always better if it produces glare.

Doug Walter writes in ProRemodeller magazine about research in kitchen lighting. He says, “Most kitchens are woefully underlit. Lighting is often an afterthought, yet even when it’s carefully planned, designers and lighting experts often don’t agree on which lamps work best in particular fixtures and where those fixtures should be located.”

In the absence of any standards, the kitchen designer or the homeowner to have to work it out for themselves. The article offers practical and technical advice about lighting the kitchen.

New South Wales said ‘no’

The building ministers from each state and territory are a group of politicians who decide what goes into the National Construction Code. Their decisions are by majority rule. In April 2021 it was decided to adopt features similar to “silver level” in all new housing. However, there was one major dissenter – New South Wales said ‘no’. The Silver level refers to that in the Livable Housing Design Guidelines. Victoria, Tasmania, Queensland, ACT and Northern Territory will be adopting the features in their jurisdiction. South Australia and Western Australia say they need a bit more time. That leaves NSW. The features will be in the 2022 edition of the NCC ready for implementation in 2023. However, it is up to each state to enforce it.

Why is NSW saying ‘no’?

One thing the construction industry wants and needs is consistency across jurisdictions. The NSW decision goes against this. Many of the larger developers are already incorporating some of the silver features, and even some gold, in their newer designs. The decision by NSW does not support this. The NSW Housing Strategy 2041 specifically supports universal design in housing. The NSW decision contradicts this. It makes no sense. So what is, or who is, the stumbling block? In the response to advocates, Kevin Anderson’s office advised, in a nutshell, that they are already doing enough. However, when questioned for evidence of this, it was not forthcoming. Without such evidence NSW cannot claim they are “already doing it”.

Livable Housing Design: a DCP approach

How many local governments in New South Wales have Livable Housing Design Guidelines in their Development Control Plans (DCP)? And what mechanisms do developers use to find this information? With different terms being used for the same thing, how do developers navigate this environment? This is what Masters student Matthew Gee Kwun Chan wanted to find out. 

aerial view of three people at a desk looking at a set of construction drawings
Chan’s literature review is broad ranging covering the complexities of housing regulation both voluntary and mandated. That’s before acknowledging the many stakeholders in the housing supply system.

The recent change to the National Construction Code (NCC) to mandate LHDG “silver” level is discussed in the context of the refusal by New South Wales to adopt this change.

NSW Government claims increased cost as the reason for not adopting the changes. This claim is challenged by economists, activists and consumers. NSW Government responses indicate that they still view the LHDG as “disability housing” not a mainstream issue. Consequently they claim there are sufficient properties available in the market and in social housing to meet current and future demand.

Local government and DCPs

Councils create DCPs to provide detailed information for implementing Environmental Planning Instruments (EPI). Some councils can seek higher accessibility standards beyond the statutory minimum. However, Chan found that councils “fail to adopt LHDG in their DCPs despite making the argument for such in other council documents”. He provides an analysis of 24 selected councils to compare their development and planning documents.

Chan claims that conflicting terminology is not the issue here. Rather, it is the amount of information, or lack thereof, about LHDG in the DCPs and where to find out more. So, the barriers to implementation are not helped when professionals lack understanding of the requirements. This is exacerbated by minor conflicts between DCPs, LHDG and Australian Standards.

The regular reference to the Adaptable Housing Standard of 1995 is also unhelpful. Document analysis reveals that each Council has its own interpretation of the LHDG and how it relates to other instruments. In some cases the references are outdated. Reference to the public domain access standard (AS1428) further complicates matters.

Brightly coloured graphic of little houses clustered together
Out of the 24 LGAs with DCPs enacting LHDG, 2 present the silver level without the hobless shower, and 2 without a stairway handrail.

Chan found that on one hand councils wanted more accessible inclusive environments, including housing, but they also wanted group homes, seniors housing and boarding houses. Some councils only encourage dwellings to LHDG while others require additional features as in the Gold and Platinum levels.

Case study

Four Sydney suburban development sites were studied: Berowra Heights, Darlinghurst, Miranda and Roseville. The analysis is necessarily technical and detailed and shows how many regulatory instruments planners and designer need to heed. The need to have an accredited assessor for some dwellings adds another step in the approval process.

There is an argument here for rationalising these instruments, particularly those relating to the design of dwellings. In the final part of the thesis, Chan challenges the NSW Government’s refusal to adopt the design features in the 2022 NCC. His rationale is that individual councils are trying to solve the problems themselves and refusal to adopt the NCC changes works against them. This is what has brought about differing provisions using different instruments across the system. And it won’t get better without adopting the silver level in the NCC.

The complexity of applying LHDG in DCPs could be solved by adopting the changes to the NCC. This would clear up most of the complexities, create a level playing field and give certainty to developers. 

Conclusions and recommendations

The thesis concludes with many recommendations. Some are related to revision of standards and related instruments. One of the recommendations for councils is to include the LHDG in their DCPs for all housing. The recommendations for the NSW Government appear to be “workarounds” on the basis of not adopting the NCC changes. The title of the thesis is, To Promote or to Limit Livable Housing Design Guidelines within Development Control Plans is the question for governments and built environmental professionals. It is available for download in Word, or download as a PDF. There is also a spreadsheet of all the councils showing those with and without DCPs requiring dwellings to LHDG.

We ain’t getting any younger

Part of the front cover of the Livable Housing Design Guidelines Why are we still building homes as if we never going to grow old? This question and others are the subject of a Building Connection magazine article about the purpose of Livable Housing Australia and their design guidelines. These guidelines, devised by industry and other stakeholders, clearly state that universal design features are easily included in regular housing and don’t need to be considered “special” just because they suit people who are older or have a disability. That’s because the features are convenient and easy to use for everyone. But why hasn’t the idea caught on in mainstream housing? 

More than half Australian households would benefit from these features. That’s because If you add together the number of older people, people with disability and those with a chronic health conditions, it comes to more than 60%. The title of the magazine article on page 42 is, We ain’t getting any younger.    

Universal design and affordability in housing

Three stacks of coins sit alongside a wooden cut-out of a house shape. Universal design and housing affordability.Housing policy people think you can’t have universal design and affordability in housing. However, the opposite is likely to be true. The national Building Ministers’ Meeting in April this year agreed to include Livable Housing Silver level in all new housing. But not all states agreed to call it up in their jurisdiction. 

Victoria, Queensland, ACT, Tasmania and NT are right behind the changes to the National Construction Code, but NSW is not. Indeed, they informed advocates by letter that they have no intention of including silver level in NSW legislation. Their reasoning is that they believe they are doing enough already. By this, they mention some policies asking for a proportion of accessible dwellings in apartments. However, there is no evidence they are actually built, and if they were, there is no way of knowing where they are.

The other reason for not changing the NSW code is that the politicians believe it costs too much. Accessible housing continues to be perceived as a niche area. A few good points were made by Kay Saville-Smith at a roundtable after the 2014 Australian Universal Design Conference. Sadly, we are still no further forward and her words hold true today. 

Universal design is affordable design

Here are Kay Saville-Smith’s five key points about universal design in housing and affordability: 

“The usual argument is that universal design is consistently unaffordable (by which they mean more costly) than poor design because of the difficulties of retrofitting the existing environment and lack of economies of scale. But the reasons why universal design is seen as costly can add cost. Five points are interesting: 

    1. Most products are not designed but driven off existing tools, processes and organisational  structures. To change these does require some investment (hump costs) but these are one off and should not be seen as an ongoing cost. Indeed, those changes can bring reduced costs in the long term through increased productivity etc.
    2. The costs of poor design are externalised onto households, other sectors or hidden unmet need.
    3. Comes out of an advocacy approach that pitches the needs of one group against another and treats universal design as special design etc.
    4. Win-win solutions need to be built with the industry participants that are hungry for share not dominant players who have incentives to retain the status quo.
    5. Universal design is different from design which is fashion based. The trick is to make universal design fashionable so no one would be seen dead without it.”

Her keynote presentation provides more information about affordability and why it is so hard to get traction with universal design in housing.

New era in home design is good for business

Everyone’s a winner in the upcoming amendments to the National Construction Code (NCC). These changes represent meaningful social change for Australia. They herald a new era in home design which is good for business as well as occupants. At last there is recognition that building design has a significant impact on the way we live our lives. So why has it taken so long for these amendments to happen? 

Housing sits in a complex web of regulations, financing, planning and market forces. The housing production system involves many stakeholders, all independent actors, but dependent on each other to maintain a level playing field. To complicate matters further, politicians decide amendments to the NCC. Consequently, the political dimension cannot be ignored. This is discussed further in the Sourceable article, A New Era in Home Design

But these changes will be good for business. With basic access features in place, modifications and renovations will become easier. Homeowners will be more willing to have modifications because it will minimise major works. Previous concerns over the value of their home will be reduced too. Smaller builders should get ready for this market.

However, the amendments to the NCC are not yet mandated. That should happen in September 2022, and there is some concern that industry will argue that this is too soon. 

There’s more work to do

In April 2021 state and territory Building Ministers agreed to include basic access features in new homes. But the Devil is in the detail. Before the changes to the NCC are mandated, a draft standard based on technical detail must be agreed. Consultation on the draft standard is currently open for comment.  Anyone can comment on the draft standard. The consultation period is open until 8 July 2021. 

To make it easier, ANUHD has shared a rough draft to help others with their comments and submissions. 

Construction code changes and home modifications

The ATSA Independent Living Expo was held alongside the UD2021 Conference in Melbourne. I used this opportunity to discuss the upcoming construction code changes and home modifications. My presentation explained the history behind the changes and what it means for the future.

State and territory Building Ministers agreed in April 2021 to amend the National Construction Code to include basic access features in new homes. This is meaningful social change for Australia, and time to re-think regular practice.

The supply of home care packages will increase and established homes will need modifications. Currently the government subsidises home modifications for this group, but modifications are not the same as renovations. 

Modifications vs Renovations

Occupational therapists assess clients and decide on functional modifications as part of a home care package. They are often done in haste and have little aesthetic value due to funding constraints. Clients often refuse these modifications because of poor aesthetics and concern about devaluing their home. On the other hand, renovations usually have a designer involved. Recent research by Monash University commissioned by the Human Rights Commission, indicates that design-led modifications will gradually increase.

With basic access features already in place, modifications and renovations will become easier. Homeowners will be more willing to have modifications because it will minimise major works, and concern over the value of the home will be reduced. The NCC changes provide an opportunity for smaller builders to capitalise on this market. The Building Designers Association Australia is already on board, and has training courses to bring designers up to speed.

The picture above shows a very poorly sited home where the distance from the front porch to the property boundary was not quite sufficient to put 12 or more steps. 

Universal design and existing homes

Modifications are different to renovations and they are not usually chosen willingly. Modifications are often work-arounds – a ramp here, a grabrail there and a rubber wedge for good luck. These tacked-on fittings fail to add value to a home and that’s why they are removed after they are needed. So we need universal design in existing homes when thinking about modifications.

UNSW has devised a free App to answer that question.

Builders and building supply businesses should also find this app very useful. The App shows how to select products and how to install them in an easy step-by-step way that allows homeowners to choose the cheapest options that suit them best. 

Home Mods – costs and gains

A man in a bright yellow T shirt is painting and archway in a wall inside a home. The wall is grey and there are tools on the floor. Accessible housing, costs and gains.The need for all new homes to have basic universal design features will continue to increase as the population ages. Evaluating the costs and gains of modifying homes is the subject of an article from Europe, Improved Housing Accessibility for Older People in Sweden and Germany: Short Term Cost and Long -Term Gains.

The authors claim that even if the costs are large, they are one time costs. Whereas costs for home services will continue. This article by Slaug, Chiatti, Oswald, Kaspar and Schmidt was originally downloaded from ResearchGate.

The personal value of home modifications is measured in quality of life and health outcomes. Research by Phillippa Carnemolla found that home modifications reduced care hours substantially. 

Costs? or Savings?

A man kneels on the floor, he is laying floor tiles.Lesley Curtis and Jennifer Beecham claim that the expertise of occupational therapists can help save money in health budgets as well as improve the lives of people needing assistance at home. Their article is about home modifications and identifying the hidden savings in providing home adaptations. They argue that significant savings can be made if you tally all aspects into the calculations. The article is available from Sage Publications. You will need institutional access for a free read.

Heavenly stairways the safe way

A man sits on the stairs in a home. The stairs are timber but there are no handrails only glass sides. The stairway is open to the living area.There is much to think about when designing and fitting stairs in a home, whether a new home or a renovation. Denver architect Doug Walters has 12 tips for safer stairways in his web article, “Beautiful Hazard”. Home stairway design should be both good looking and safe. The article uses photos to illustrate points.

There is a link to some elegant solutions. I note that nothing is said about extending the handrail to the final tread in some examples.

An article on stairway design using architecture magazine pictures, researchers found the lack of handrails occurred most often. The article includes several photographs and a list of the missing safety features. Available on ReseachGate

The Australian Human Rights Commission produced a document in 2008, “The Good, The Bad and the Ugly”, and it focuses on stairways and the placement of tactiles, handrails, and contrasting nosings – a good reference guide on what not to do.

Adaptable Housing Guide – 6th edition

Front cover of Your Home 6th edition. Your Home is in its 6th edition (2022) published by the Australian Government. It has a section on the livable and adaptable house. This guide is especially helpful for home renovations and modifications as well as new builds.

Accessible, universal design features for all housing are in the 2022 edition of the National Construction Code. These features are similar to the Livable Housing Design Guidelines Silver standard. However, Your Home Guide is yet to catch up with the recent changes to the National Construction Code’s Livable Housing Design Standard.

The old Adaptable Housing Standard (AS4299) continues to be referenced alongside the Livable Housing Design Guidelines. The Adaptable Standard has elements similar to the Gold standard in the Livable Housing guide. However, some elements and design ideas are outdated in this 1995 standard. 

The web version is easy to navigate and covers every aspect of design including adaptation to climate change. It can also be purchased in hard copy. 

There are many detailed diagrams to help explain design features and floor plans. The chapter makes distinctions between liveable and adaptable designs. Drawings and floor plans provide sufficient information for designers, renovators and homeowners alike. 

From the introduction:

Many of the homes we build today will still be in use in 50 or even 100 years. Ensuring our homes are both liveable and adaptable is a key challenge for all communities.

Liveability means ensuring our homes are comfortable, healthy, efficient and connected to the community. But it also means the home is functional, safe, secure and attractive for current and future occupants.

Adaptability means that our homes can cope with changes to our households and to the climate. Making homes that are flexible, adaptable, and resilient helps us to respond to both predicted and unexpected change. It also means that we limit our environmental footprint to ensure that our communities remain sustainable.

Going for Gold but Silver will do for now

shows roof tops of a development in a greenfield area. Photo taken from the top of a hill looking down.At last! The national Building Ministers’ Meeting agreed to change the building code to mandate accessible features in all new homes. This represents a major social change in Australia. While evidence showed that Gold level of Livable Housing Design Guidelines was the most cost effective, Silver will do for now.  However, there is still work to do.

The building ministers were not unanimous in their decision. The Communique released after their meeting gives states and territories discretion in applying the changes. It states, “Each state and territory will be free to determine whether and how the new provisions will be applied in their jurisdiction to minimise the regulatory impact on the construction sector.”

WA, NSW and SA do not support the changes. That means they will not adopt them in their state based legislation – at least, not right away. Queensland and Victoria are keen to get going with the new legislation. 

Potentially, the property industry will find it inconvenient to work with differing codes across jurisdictions and decide to conform regardless. But that will mean longer time frames before full implementation. It also means more confusion for everyone.

So, from October 2022, those states that support the changes will have new homes designed to Silver level. A voluntary guide for Gold will be developed to encourage the industry to go beyond minimum. This will be a better match for the old adaptable housing standard AS4299 for those who want to go beyond minimums.

Who said what to the CRPD Committee about housing

House half built showing timber frameworkThe international Committee on the Rights of Persons with Disability asked Australia some important questions about accessible housing. The answers depend on who you ask. The Australian Government indicated it was doing OK. Australian Human Rights Commission said a lot more needed to be done, including regulation. The Australian Civil Society Report, which provides the perspective of people with disability, said aspirational targets by industry haven’t worked, so it has to be mandated. 

Australian Network on Universal Housing design has more detail and links to the various documents: Who said what to the CRPD Committee about Australia’s lack of accessible housing

The advocates

The Australian Network for Universal Housing Design (ANUHD) led the campaign for change for almost 20 years. ANUHD is a national network of committed volunteers who meet via Zoom every month. Dr Margaret Ward’s leadership and determination were instrumental to the campaign’s success. Her many letters over many years to politicians and others in power positions eventually paid off. Make no mistake, this change was not given willingly. And that is the never-ending story of all human rights campaigns. 

The success of the campaign is also due to the recent push by the Summer Foundation and their financial support for extra research and a campaign director.  

CUDA has actively supported the campaign and congratulates all involved. This issue has been a regular feature across the six years of this website. If you are interested in the history, the section of this website on Housing Design Policy has several posts. Universal Design in Housing in Australia: Getting to Yes, by Dr Ward provides an history of the campaign and the barriers advocates faced.
