This design guide aims to improve infrastructure for people wanting to walk, cycle, scoot, and ride mobility devices. That means anyone and everyone who is not a driver of a motor vehicle. This is part of the ACT Government’s policy is to support active travel.
In the Canberra context, unless designated, all paths are shared by people walking, wheeling, cycling and using mobility aids.
Few people fully understand road rules, which is why design treatments must indicate that pedestrians have priority.
People using mobility devices and older people are given the label of “vulnerable” pedestrians. This is default language in transport jargon, but serves, unfortunately, to reinforce stereotypes. In reality, all pedestrians are vulnerable compared to motor vehicles.
When all pedestrians are incorporated into designs, we should just talk about “pedestrians walking and wheeling”. And with a Safe Systems Approach there should be no delineation between who is safer than whom.
Movement and Place framework
The Movement and Place framework together with a Safe Systems approach puts people into the centre of the frame. The lens has always been on vehicle traffic flows and the convenience and economics of reducing traffic delays. If we are to have active travel really happening, we have to re-think this priority.
The Design Guide is comprehensive and serves as a “how-to” tool for transport planners. It covers:
A touch of universal design thinking has entered the design of bathroom design and fittings. Research from many quarters has established that people want to stay home in their later years. Consequently designers need to get on board with designs that are functional and look good too. A whitepaper from Nero Tapware updates designers on bathroom aesthetics and accessibility.
“Accessible living spaces are becoming increasingly important as the majority of Australians, both with and without disabilities, have a desire to stay in their current homes rather than enter residential aged care.”
The Nero whitepaper discusses the many aspects of design in the context of the new Livable Housing Design Standard in the National Construction Code. However, their bathroom layout and overall style is similar to the public bathroom design. A universal design approach would use the space creatively and leave out grab rails until, or unless they were needed. That’s because grab rails placement needs to fit the individual user’s requirements.
“By modifications to our built environment, architects and designers can promote usability, participation in activities, and enable older users to live comfortably and independently.”
It is good to see product designers preparing to align with the new Livable Housing Design Standard. However, the photographs in the whitepaper do not align with the universal design concept of the Standard. That is, each picture shows grab rails which are not part of the Standard. However, reinforcement in the walls is required so that grab rails can be added later at any placement the user needs.
Aesthetics impact wellbeing
The whitepaper nicely spells out all the issues including the importance of wellbeing. It notes that a liveable home must be multifunctional and it must feel like home. Lack of colour matching and styling options can end up looking clinical. The whitepaper argues that end users feel undervalued, neglected and uncared for.
The Mecca range is specifically for people who require assistive living designs. While the photographs show nicely designed bathrooms, grab rails take the look and feel away from a “conventional” bathroom. But if these fixtures and fittings keep you at home for longer then at least they can look good. Wall hung toilet pans, however, are a good idea for any home.
Universal in-wall bodies
A companion Nero whitepaper is A Universal Approach to Bathroom Installation. The in-wall body is an installation that separates the in-wall body from the trim kit – the visible bits. In-wall bodies allow builders and customers to select the right fittings after tilers have finished. Customers can delay their design decision informed by the latest trends. At a later date home owners can update their fittings without affecting walls and tiles.

Thinking of wheelchair users…
Lifemark in New Zealand has a handy little brochure that sets out bathroom dimensions and placement of fittings for wheelchair users. They use the term universal design because the features can be used by most people. However, they do look as if they are specifically designed for wheelchair users. And there is no need to make this look like a hospital.
Designers can still be creative and provide style with colour and attractive fittings. One thing the brochure does not mention is colour contrast for people with low vision. Contrast between the floor and the wall is important, and for some, contrasting fittings work well.
The title of the brochure is Universally Designed Bathrooms. Of course, the bathroom is only one element in a home that needs to be accessible for a wheelchair user.
There are many tools for measuring environmental sustainability features in the built environment. But measuring access for all, is based on legislation and cost rather than user-based. Indeed, building standards for disability access have filled this knowledge gap but in the process, held back learning at the same time. That’s because you learn how to complete checklists but you don’t gain understanding of the issues this way. This is one reason that architect Mary Ann Jackson says built environment practitioners do not understand disability.
Neighbourhood scale accessibility measurement tools show how improvements can be determined in a planned way rather than ad hoc reactions.
Built environment knowledge and the lived experience of people with disability need connection. We need a tool that measures the overall accessibility of the built environment by incorporating the lived experiences of people with disability.
Increasingly, assessment of the built environment is becoming interdiciplinary. However, despite all the many built environment performance tools, input from people with disability are often left out of the equation. The move to co-design methods for new work is helpful, but does little to deal with existing built environments.
The existing built environment still fails to meet the needs of people with disability. This is despite rapid urbanisation, population ageing, failing infrastructure, and evidence that the built environment affects health and well-being,
In a parallel universe, improving built environment ‘sustainability’ performance, via measurement, receives much attention. Analysing the built environment at micro-scale (buildings), meso-scale (neighbourhood) and macro-scale (city-wide) is undertaken from various multidisciplinary perspectives.
Built environment performance is measured in many ways, but accessibility performance for people with disability, at neighbourhood scale, is rarely considered.
People with disability continue to experience lack of meaningful involvement in research, participation in decision-making, partnership equality, and direct influence over policy, with the built environment arena increasingly becoming a private-sector activity.
The actors involved, however, have little understanding of either the accessibility needs of people with disability, or the inaccessibility, particularly at neighbourhood scale, of the existing built environment.
This paper explores the design, planning and politics of an inaccessible built environment. Assessing the accessibility of the built environment for people with disability, at neighbourhood scale, is an essential component in the process of built environment accessibility improvement. As a result of collaboration between the domains of the built environment and disability, a new tool, Universal Mobility Index, has emerged and is undergoing further development.
The Royal Institute of British Architects has updated their Access Audit Handbook in conjunction with the Centre for Accessible Environments. Access auditing is an evolving concept and means different things to different people. Some take it as being compliant with a standard while others consider aspects beyond compliance.
Fortunately, the Ergonomics in Design for All Newsletter explains the content of the document. In doing so, the newsletter provides an synopsis of some of the key concepts in the handbook.
Similarly to Australian Standards, British Standards only apply to people with disability and do not cover any other groups in terms of access and inclusion. This is despite other groups who fall under anti-discrimination law. The handbook addresses some of these gaps. For example:
Faith spaces, prayer facilities, features relating to women’s safety and their well-being, including pregnancy and menopause, baby feeding and changing, and non-gendered sanitary and changing facilities.
There is guidance on neurodiversity and reducing sensory overload, anxiety and stress, such as quiet rooms. Designers are asked to plan logical wayfinding with straight lines, and create curves rather than corners.
Technology is evolving on building accessibility, space and wayfinding, and auditors need to keep up with these developments. Lift destination control systems are a case in point where people no longer press a button for their floor. The central control system can be very confusing where there is a bank of lifts.
Case studies
The handbook recommends engaging with building users for insights into the level of accessibility and to keep them engaged throughout the project. There are six case studies: a theatre, a zoo, a parish church, a university science lab, and an outdoor space. The case study of an inaccessible heritage town hall shows how to create an accessible community building.
The handbook has 32 checklists for the external environment, internal building space, management and communication.
Do stereotypes of older people affect how digital technology is designed? A team of researchers found that ageism influences digital design in negative ways. However, they found co-design partnerships overcame ageist attitudes and produced needed and used digital technologies.
Ageism can have a detrimental role in how digital technologies are designed. Participating with older people in the design process has the additional benefit of countering stereotypes. Image shows a group of older people on a desert camping expedition.
Older people said the “ultimate partnership” in co-designing is to involve them from the beginning through to the end of the design process. Sharing control over design decisions was an important part of the process. They are more than informants – they are equals who have valuable contributions.
The researchers noted that although this vision of co-design is shared by designers, it is not always the case in practice.
Image shows older people working together on a workshop question.
Older people in the study also said that ageism emerges in implicit and explicit language about ageing. And ageist images can influence the design process. Consequently, the researchers say it is important to view the diversity of older people.
Co-design with older people
How and when to involve older people in digital design is also important. Understanding co-design with older people has the potential for avoiding insufficient prototyping, biases and errors in the design process.
There is a gap between the ideal of involving older persons throughout the design process of digital technology, and actual practice.
Twenty-one older people participated in three focus groups. Participants experienced ageism in their daily lives and interactions with the designers during the design process. Negative images of ageing are potential influencing factor on design decisions. Nevertheless, positive experiences of inclusive design pointed out the importance of “partnership” in the design process.
The “ultimate partnership” in co-designing is to involve older people from the beginning, iteratively, in a participatory approach. Such processes were perceived as leading to successful design outcomes, which they would like to use, and reduced intergenerational tension.
The Centre for Accessible Environments in London has been providing access advice for many years, many of them heritage buildings. As a not-for-profit, their aim is for more mainstream buildings to be accessible and inclusive. They got the chance with the office space for the Royal College of Occupational Therapists (RCOT). The Centre for Accessible Environments (CAE) website has an overview of the work they did on this building.
The image shows the accessible shower room prior to the refit. The design is based on a public standard and looks very clinical.
Image from the CAE website.
The building accommodates around 90 staff across four floors with meeting rooms on the ground floor. This floor had level access, powered doors, and an accessible shower room that looked like a hospital room. Not what CAE would consider gold standard.
The image shows the same wheelchair accessible shower room but with improved colour aesthetics. While this might meet British Standards, Australian access consultants might take issue with some aspects. The placement of the mirror, for example.
Image from the CAE website.
The outcome of CAE’s involvement is that the fit-out of the shower room looked less clinical despite the considerable amount of specialised equipment and features. The overall success was the focus on detail such as the amount of pile in a rug.
Quiet spaces and soundproofing and height adjustable desks are also part of the fitout. CAE’s access consultant also acknowledge that flexibility of space is essential. “Until people use a building following a redesign, you don’t know if it’s going to meet the needs of everyone.
The pandemic forced may activities online and into the virtual world. It was a steep learning curve for everyone, especially in terms of making and keeping things inclusive. While many prefer in-person conferences and learning events, there are others who prefer online participation. The pandemic has therefore given people choice through hybrid events – they can choose which one suits them best.
The anytime, anywhere availability of the internet provides flexibility for learning and for participation in conferences.
Anne Fensie reflects on her experience as a teacher, learner and conference delegate in a short piece, Inclusion Possibilities. She is unable to travel and the hybrid option is perfect, and she sees this as an issue of equity. As a person with ADHD and a sensory processing disorder it makes it difficult to focus in large venues with lots of people.
“There are many financial, logistic, physical and social barriers to attending these events in person… particularly people with disability…”
Fensie urges conference organisers to consider the principles of Universal Design for Learning (UDL) when planning a virtual or hybrid event. That means, multiple means of engagement, representation, and action and expression.Her “musings“ on hybrid events are an easy read where she explains things from a user perspective. As she says, “Designing an event that benefits any person improves the experience for every person.
We know that connecting with nature is essential for our mental and physical health. The recent pandemic made that clear. Creating accessible parks and wilderness areas is more than just considering how a wheelchair user might navigate the terrain. Different people have different ways of connecting with nature that is meaningful for them.
A report for the National Trust in the UK brings together practical information about accessibility for different groups of people. The report is based on a new site acquired by the National Trust in Lincolnshire. Image is of Sandilands Beach (National Trust)
Age, cultural background, socioeconomic status and disability are all considered in the report’s practical considerations. The focus is on the accessibility of external spaces because the overall focus is on access to nature.
The report covers detail on the usual elements such as:
Easy to navigate website with relevant access information
Lighting around key facilities
Toilets that can accommodate mobility scooters and wheelchairs, and relief areas for dogs
Signage and maps of walks and paths
Parking, transport and toilets have more detail together with paths and routes.
Paths and routes
Footway treatments are especially important as well as providing multiple paths so that visitors can choose the most suitable one. In the UK the Fieldfare Trust has a guide for different types and specifications for footpaths in different locations. They cover everything from peri-urban to wilderness. Disabled Ramblers have three categories of paths that they use to describe routes and paths.
The report goes into more detail about path surfaces, widths, gradients and accessible gates. Benches, shelters, bridges, boardwalks and viewing platforms are covered as well.
Connecting with nature
This section of the report covers the diverse range of visitors and how they best connect with nature. The section of age, covers the different needs of children, adolescents and older adults. Little is known why certain ethnic minority groups are less likely to use green spaces. However, they are more likely to use them in groups rather than alone. People with lower incomes visit green spaces less often and more needs to be done to change this.
Lack of access to transport to green space is a key barrier for people with disability. Physical barriers are also a problem but the way that service people treat them is another downside to visiting nature.
A Danish study used satellite data to show a link between growing up near green space and issues with mental health in adulthood. They found that children under 10 years who had greater access to green space may grow up to be happier adults.
The FastCo article goes on to say that data was correlated between the child’s proximity to green space during childhood and that same person’s mental health later in life. The more green space they had access to, the less likely they were to have mental health issues later.
Universal design concepts in their pure form are about creativity rather than set standards. However, building practitioners want more guidance than “make it inclusive and accessible for all”. Two researchers in Canada have attempted to solve this dilemma by connecting universal design and BIM (Building Information Modelling).
BIM is a process that uses tools and technologies to form digital representations of physical and functional aspects of places. Building professionals use this information across a wide spectrum of infrastructure. Weaving universal design principles into BIM processes is essential if we are to create an inclusive built environment.
“Accessibility is a compensatory strategy conceived to prevent discrimination while universal design seeks to change the consciousness of those who create the built environment to address a broader conception of the human body.” – Prof Ed Steinfeld in,The space of accessibility and universal design.

In their paper, the researchers describe the process of developing a model that integrates the BIM database with universal design. In a nutshell, the researchers established a database of universal design elements for designing homes. Then they turned it into a plugin for the BIM system.
“It is recommended that the construction industry starts following the universal design guidelines in new buildings… to increase the lifespan… and reduce the need for future adaptation.”
Beginning at the conceptual stage
The paper explains in technical terms the creation of the model and database leading to the BIM plugin for universal design. The authors claim designers can instantly access universal design standards and incorporate them at the conceptual stage.
There is a similar shorter version of the same study on ResearchGate, titled, Building Information Modeling with Universal Design Requirements for High Accessible Homes. This paper has a case example of a four storey home with four apartments on each floor. Universal design “families” – windows, doors, floors, etc., are applied to create a 3D view and and floor plan. The images in the paper show the results. The paper explains in technical terms how the model was developed and then applied in the case example.
From the abstract
A projection of the Canadian population shows that in 2024 one in five Canadians will be over 65 years old. This shift forces designers to consider the entire lifetime of occupants during the design of new buildings. Universal design aims to house people irrespective of their age, ability, and chronic health conditions.
Building Information Modeling (BIM) significantly helps advance the development of the Architecture, Engineering, and Construction industry in a more collaborative and automated way. Integrating BIM and universal design allows designers to incorporate universal design at the conceptual design stage using the functionalities of BIM tools.
This study presents the development of an automated computer model to facilitate the adoption of universal design processes. A newly created plug-in will assist designers to incorporate universal design at the conception stage.
Public Engagement, Virtual Reality and BIM
This study compares VR platforms for community engagement with a view to creating plugins for the BIM system. The results of this experimental study found significant potential for utilising the methods and tools as part of a collaborative approach to design. This was particularly the case for designing a refurbishing public spaces.
The participants enjoyed using the tools that helped them understand design features and quality. It helped them engage and visualise intricate and challenging aspects of the project. If designers are serious about co-designing with users, having the right tools is the key to success. They move participants past ad hoc discussions to focused thinking.
The title of the study is Enhancing Public Engagement in Architectural Design: A comparative Analysis of Advanced Virtual Reality Approaches in Building Information Modeling and Gamification Techniques. The article is open access.
BIM and accessible bathrooms
There is a related article on BIM and the evaluation of accessible bathrooms. Here is a short extract from the Abstract:
This study aims to demonstrate the practicability and utility of emerging BIM and related digital technologies, applied in the field. Post occupancy evaluation is key to ensuring building access is provided and maintained. Twenty-one accessible bathrooms in three university buildings were assessed in this study.
The study found that across all bathrooms the toilet roll location is unsatisfactory. Other high-risk issues included: Approach: access; Entrance: door fittings and security; and Layout: hazards. The study shows how low-cost BIM and related technologies can form a baseline for ongoing post occupancy evaluation.
Microsoft wants designers to see beyond physical and sensory disabilities. So they have updated their popular Inclusive Design Toolkit to include cognition – the brain. Cognition is about getting, storing and retrieving information. It’s also about focusing, learning, memorising and making decisions. So how to design for people who process thoughts in different ways?
Microsoft launched it’s first inclusive design toolkit in 2015, but it only focused on physical and sensory disabilities. The second edition takes a broader approach to address cognitive exclusion.
The new toolkit has three key principles for cognition, which can be applied in many other design contexts:
Understand the user’s motivation, and the goals and tasks they are trying to complete.
Discern the cognitive load required to reduce that mismatch.
Co-create the final product with a diverse community of people across the spectrum.
The toolkit is not about specific industries or specific conditions. Rather it encourages designers to collaborate with users and find out first hand how they learn and think. The Inclusive Design 101 Guidebook has the basics. The Inclusive Design Cognitive Exclusion is a separate document.
The toolkit and guides are useful for anyone who wants to learn how to design inclusively – to take a universal design approach to design.
FastCompany has an article about the Inclusive Design Toolkit’s development. Christina Mallon, Microsoft’s head of inclusive design, discloses that she has ADHD. She couldn’t complete certain tasks and felt stupid. When she learned about inclusive design she realised that she was not stupid, just designed out of products. Now she just wants her job to be just a designer, not an inclusive designer. The title of the article is, Microsoft’s new Inclusive Design Toolkit is designed for the brain.
