How Universal Design helps create homes that remain accessible, adaptable and inclusive throughout life.
When people think about accessible design in architecture, they often picture wheelchair ramps, accessible parking spaces or grab rails. While these are important accessible features, they represent only a small part of what accessibility really means.
The Building Regulations, including Approved Document Part M, establish important minimum standards for access. However, truly accessible design goes beyond compliance. It begins by understanding the people who will use a space and recognising that no two people experience the built environment in the same exact way.
This matters most when designing our homes, since they are places we hope will support us through every stage of our lives. Accessibility should therefore be treated as a fundamental part of good residential design.
In this article, we will explore why accessibility matters, how people’s needs change over time, why the earliest design decisions carry the most weight and how Universal Design gives architects a practical framework for creating homes that work for the widest possible range of people.
Why Accessibility Is Important
Every person experiences the built environment differently. Our bodies, senses, circumstances and ways of processing information all vary. Some differences are immediately visible, while others remain hidden. In addition to this, our physical and cognitive abilities are also not fixed. They change throughout our lives; in ways we cannot often predict.
Ageing is perhaps the most universal example. The world experienced by a two-year-old is vastly different from that of a thirty-year-old. Earlier in life, door handles are out of reach, worktops are too high, and stairs can feel like impossible obstacles. Later in life, reduced strength, balance, vision or hearing can make the same home we were once used to, much more difficult to use.
Alongside this natural progression, illness, injury and changes in physical or mental health can also affect how people interact with the built environment. These changes may be temporary, permanent or ones that fluctuate on a daily basis.
People’s lived experiences are equally diverse. Some people are born with disabilities, while others acquire them through illness, injury or ageing. Disabilities may affect movement, strength or dexterity, and may influence sight, hearing, communication, learning, memory, attention or sensory processing.
Many disabilities are hidden too. While some people use visible mobility aids like wheelchairs, crutches, walking frames, mobility scooters or guide dogs, countless others live with conditions that are not immediately apparent but still shape how they use and understand a space. Some individuals may experience several conditions at the same time.

So, you can see when buildings are designed around the ‘average’ person, they unintentionally leave many others behind. Good accessible design benefits a wide range of people, including:
- Wheelchair users
- People with limited mobility
- Elderly
- Children
- Parents with prams/pushchairs/buggies
- People recovering from injury or surgery
- People carrying shopping or luggage
- People with visual impairments
- People with hearing impairments
- Neurodivergent people (including autistic people and people with ADHD, dyslexia and related conditions)
- People living with chronic illness or invisible disabilities
- Carers and support workers
A well-designed home supports people across this broad range of experiences. It can provide independence for someone who uses a wheelchair, reduce fatigue for a person living with multiple sclerosis, make everyday life easier for parents with young children, or help an older couple remain in their home for longer.
Recognising this diversity is only the first step. The next challenge is designing homes that can continue supporting people as their needs inevitably change.
Designing for Changing Needs
Our homes are built to last for decades and often outlive several generations of occupants. While furniture and finishes are replaced over time, the fundamental layout and structure of a home are far more difficult to change.
As we have already explored, people’s needs are rarely static. Ageing, illness, injury and changing circumstances all influence how we experience our homes. Rather than designing solely for the needs of today’s occupants, we have an opportunity to create homes that can accommodate changing circumstances with minimal disruption.
This approach is not about predicting every future requirement or designing every home as though it were already adapted. Instead, it is about preserving flexibility so that the home can evolve alongside the people who live there.
Small but thoughtful decisions can often have the greatest long-term impact. A modest amount of additional space, structural planning for flexibility may seem insignificant when a home is first occupied. Years later, that same decision may determine whether someone can continue living there independently or is forced to move.
If flexibility is the goal, timing is the key variable and nowhere is that truer than at the very start of a project.
Accessibility Starts at the Earliest Design Stages
Many of the decisions that have the greatest impact on accessibility are made at the very beginning of the design process. Early design choices shape how people approach, enter and move through a home. They influence both its immediate use and long-term adaptability.
These decisions include:
- the position and orientation of the building on its site
- the relationship between parking, pedestrian routes and the entrance
- changes in ground and floor levels
- the location and design of the main entrance
- the overall circulation strategy
- the relationship between main rooms
- structural decisions that may support or limit future adaptation
Since these decisions are made during the briefing and concept design stages, they present the greatest opportunity to integrate accessibility into the overall design. At this point, changes can be explored with minimal cost or disruption. Once construction begins, opportunities to improve accessibility can become challenging and expensive to carry out.
The early design stages also provide an opportunity to challenge assumptions and develop a clearer understanding of who will use the home. Engaging clients, future residents or people with lived experience, where appropriate, can identify priorities that standards and technical guidance alone may not reveal. While regulations provide an essential baseline, they should not define the limits of good accessible design.
Accessibility is therefore not simply a matter of compliance or technical detailing. It is a fundamental design principle that should shape the spatial organisation and flexibility of a home from the outset.
Integrating accessibility early, results in homes that are capable of supporting a wider range of people throughout different stages of life. It also allows accessibility to be resolved as an inherent part of the architecture rather than as a series of later interventions.
However, early decisions only set the framework. They create the conditions for a home to work well, but they do not guarantee it. Accessibility needs to remain part of the conversation through detailed design, specification and construction, not just the initial concept.
A well-considered layout can still be undermined by a later change. Thus, carrying accessibility through to completion is what turns good intentions at the concept stage into a home that genuinely works for the people who live in it.
Knowing when to act on accessibility is only half the picture. We also need a framework for how to think about it. This is where Universal Design comes in.
Universal Design Principles
The way we think about accessibility has changed considerably over time. Historically, disability was often addressed through segregation. People were accommodated in specialist institutions rather than being included within society.
Over the past century, attitudes have gradually shifted towards creating environments that enable people to participate more independently in everyday life. The timeline below illustrates this evolution.
The book Designing for the Disabled published in 1963 by British architect Selwyn Goldsmith’s (1932-2011) marked an important shift in British architectural thinking by demonstrating that accessibility could be integrated into everyday design rather than being treated as a specialist requirement. He helped develop practical design solutions like dropped kerbs, demonstrating how relatively simple interventions could improve the built environment for the benefit of its diverse users.
Over the following decades, this approach gathered momentum through disability rights movements and legislation, including the Disability Discrimination Act 1995 and later the Equality Act 2010, both of which strengthened the emphasis on removing barriers and promoting equality of access.
Around the same time, the American architect Ronald Mace (1942-1998) popularised the term Universal Design, advocating for environments that could be used by the vast majority of people from the outset. Although originating in the United States, the principles of Universal Design have influenced inclusive design thinking internationally and continue to inform architectural practice today.
At its heart, Universal Design asks a simple question:
There are seven principles of Universal Design:
Equitable Use
The design is useful and marketable to people with diverse abilities.
Flexibility in Use
The design accommodates a wide range of individual preferences and abilities.
Simple and Intuitive Use
Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
Perceptible Information
The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
Tolerance for Error
The design minimises hazards and the adverse consequences of accidental or unintended actions.
Low Physical Effort
The design can be used efficiently and comfortably and with a minimum of fatigue.
Size and Space for Approach and Use
Appropriate size and space is provided for approach, reach, manipulation, and use regardless of the user’s body size, posture, or mobility.
Universal Design provides a useful way of thinking about accessibility. But in practice, architects still have to work within a legal and regulatory framework.
Going Beyond Minimum Standards
In England, the Building Regulations establish the legal requirements for accessible design, with Approved Document M providing practical guidance on how these requirements can be met. Alongside this, BS 8300-1 and BS 8300-2 offer more detailed recommendations for inclusive design in the external and built environment respectively, while BS 9266 sets out specific standards for accessible and adaptable general needs housing.
Regulations work through thresholds with minimum door widths, minimum turning circles, minimum reach ranges etc because that is the only way a standard can be applied consistently across every building in the country. This same generality is what makes compliance an incomplete measure of success. A home can meet every relevant Part M requirement and still not work for the person living in it.
Good accessibility isn’t just measured by dimensions, but by how comfortably and confidently people can use a space.
Designing beyond the minimum also has long-term benefits. Homes that can respond to changing needs are likely to remain useful to their occupants for longer while also appealing to a wider range of future residents.
Ultimately, accessibility should feel like an integral part of the architecture rather than an added feature. The best inclusive design is often almost invisible, not because accessibility is absent, but because it has been considered so thoroughly that the building simply feels intuitive and welcoming.
Sometimes the most valuable design decisions are not measured only in millimetres. They are measured by how confidently and comfortably people can live their everyday lives.

Key Takeaways
Accessibility should not be viewed as a specialist addition or simply a matter of regulatory compliance. It should be a lens every architect designs through because every person we design for experiences the built environment differently.
Our needs are not fixed and therefore our homes should be designed not only for the needs of today but should also hold space for the needs of the years and decades ahead.
The earliest stages of a project carry the most weight, but accessibility shouldn’t stop being considered once the concept is finalised. It needs to be an important part of the conversation through later stages like detailed design, specification and delivery.
Universal Design provides us a valuable framework for creating homes that help support a wide range of people with diverse needs.
Building Regulations and technical standards remain essential, but they establish only the minimum acceptable level of accessibility. Good design goes further than this by considering the comfort, dignity, independence and everyday experience of the people who will use the space.
