Architecture For All and the UIA Year of Design for Health by Belinda Seale (Australian UIA AFA Rep) & Allen Kong (UIA AFA Co-Director)

Belinda Seale is the Principal Architect and Access Consultant at Haptic Space, with over 20 years’ experience in the design and delivery of enabling and therapeutic environments. She chairs the Australian Institute of Architects Victorian Enabling Architecture Committee, serves on the National Enabling Architecture Committee, and represents the Institute on the International Union of Architects (UIA) Architecture for All Work Group. She is currently a PhD candidate at Deakin University, undertaking research into rehabilitation environments. Allen Kong is the Director of Allen Kong Architect. Allen’s cultural background has influenced his conceptual framework for his holistic view of architecture. He blends evidence-based design with the inalienable understanding of the living spirit relationship AKA work has been recognised with many international awards including UN World Habitat Award and UN Scroll of Honour for Human Settlements, UIA Architecture for All; World Congress of Health and Design for Salutogenic Design. Both World Architecture News and Banksia Foundation Design for Sustainability. Allen has further roles as Co-Chair of International Union of Architecture (UIA) Architecture for All Work programme, Co-Chair and Director of Indigenous Architecture and Design Victoria (IADV), Convenor of RAIA National Enabling Architecture Committee, Member of Building Appeals Board Victoria (BAB) and Sustainable Architecture Forum Victoria.


he Covid-19 pandemic has highlighted the role the built environment can play in both spreading and controlling disease, as well as the importance of healthy, safe environments for all. It is in this context that the International Union of Architects (UIA) has declared 2022 as the UIA Year of Design for Health, encouraging architects to use evidence-based design to promote health in buildings and cities. The UIA is a non-government federation of national architectural organisations from 115 countries and territories worldwide. It was founded in 1948 with the aim of uniting architects around the world, providing a platform for sharing knowledge, innovation and collaborative solutions, with a particular focus on sustainable development. The UIA is made up of five regions, a governing Council, a range of work groups and commissions, and organises triennial congresses, forums and international design competitions1. The Australian Institute of Architects (RAIA) is a member of the UIA in Region IV - Asia and Oceania, and has representatives on the Council, the Sustainable Development Goals Commission and various work groups, including the Architecture for All work group with ACAA members Allen Kong (co-Director), Belinda Seale and Eric Martin all currently representing the RAIA. The Architecture for All Work Programme (AfA WP) aims to raise awareness of architects’ responsibilities to design accessible and inclusive environments and promote good practice in this area. The triennial UIA Friendly and Inclusive Spaces Awards is organised by the group to 1 UIA website

The AfA WP also facilitates a network of architects with expertise and experience in accessible and inclusive design, compiles and disseminates best practice case studies, education and training material, participates in developing international standards and guidelines, advises governmental and non-governmental organisations and participates in conferences, exhibitions, seminars and competition juries2.

The meticulous rehabilitation of a listed medieval palace in Barcelona for the creation of four independent living units for 48 people with physical disabilities provides quality housing in an old part of town, while breathing new life into a heritage structure. La Residencia Vigatans was completed for Associacio Civica d’Ajuda Mutua by Arquitectura i Accessibilitat, architects Carla Habif Hassid, Xavier Garcia- Mila and Jaume Cardona.

FRIENDLY AND INCLUSIVE SPACES AWARDS Entries in the Friendly and Inclusive Spaces Awards must demonstrate the highest standards of universal and inclusive design, contributing to the quality of life for all who use them. Award categories include New Buildings, Refurbished Existing including Historic Buildings, Public and Open Spaces and Research and entries are accepted from architect members of a UIA Member Section. Aspects considered include architecture which enhances users experience through friendly scale, form, colour, material and light; takes account of human diversity and needs; and facilitates orientation, wayfinding and ease of understanding. Evidence based research is assessed on its contribution to improved quality of life through facilitating a better understanding of user centred design, its applicability and effectiveness for use to enhance design quality and create friendly and inclusive spaces. The awards were first held in 2014, with the year’s research award winners including ‘Autism ASPECTSS Design Index’ by Magda Mosafa3. It was noted as the first set of evidencebased design guidelines worldwide to address built environments for individuals with Autism Spectrum Disorder. In 2017 amongst the fine entries were two examples of building refurbishments which meld inclusion and access with the effective and sustainable reuse of the built fabric, both demonstrating carefully considered design decisions to achieve balanced outcomes. 2 AfA website 3

Coogee SLSC awarded by International Olympic and Paralympic Committees by Allen Jack+Cottier

Changing the way people live, work and play, Allen Jack+Cottier (AJ+C) is a Sydney-based practice for architecture, urban design and interiors. Over six decades the practice has created some of Australia’s most innovative, celebrated and sustainable environments in sport, education housing, community and urban design



e’re incredibly proud to share the news that Coogee SLSC has won the IPC/IAKS Distinction for Accessibility at the 2021 IOC IPC IAKS Architecture Prizes in Cologne, Germany. A hub for community in Sydney’s southeast, Coogee SLSC is one of Australia’s oldest surf lifesaving clubs, patrolling a beach of over 4 million visits each year. It reopened in December 2020 after a transformative redesign of the club house following its severe storm-damage in 2016.


In collaboration with Randwick City Council and Coogee SLSC, Allen Jack +Cottier Architects (AJ+C) redesigned the club house, expanding its teaching and events facilities to greatly improve the Club’s capacity to train new life savers, patrol the beach and generate revenue for its vital work. Design of the now single-level club house, with a new lens-like view to the beach, and elevator to all levels, created all-ability access for the first time in Club history, enabling people with different physical abilities to become surf lifesavers at Coogee. It’s been so successful, that it will soon be a pilot site for other surf lifesaving clubs becoming more inclusive.



It’s especially gratifying for AJ+C, having previously received a Silver Medal at the IOC IPC IAKS Architecture Prizes (2013) for Milson Island Sports & Recreation Centre.

the Club’s capacity to train new life savers, patrol the beach and generate revenue for its vital work.

These awards recognise excellence in the design and operation of fully inclusive and universally accessible indoor and outdoor facilities and are organised jointly by the International Olympic Committee (IOC), the International Paralympic Committee (IPC) and the International Association for Sports and Leisure Facilities (IAKS).

For over a century, Coogee SLSC has patrolled the beach, trained an army of volunteer lifesavers and been a community hub for schools and scouts, sports events and local celebrations, all based around this building. Today Coogee Beach attracts around 4 million visitors a year.

An official awards ceremony took place in Cologne/Germany, at the international IAKS Congress and FSB trade show. “It’s humbling and gratifying to be recognised by the International Olympic and Paralympic Committees and IAKS for this project, which has been a labour of love for so many. Redesigning the Coogee SLSC was about so much more than repairing and extending the building. Its transformation not only secures the Club’s financial future with peerless new facilities, it’s also opened new pathways for people of all abilities to become surf lifesavers. I can’t think of a greater community legacy than breaking down barriers to inclusion.” — Michael Heenan, Director & CEO, AJ+C Architects

ABOUT THE COOGEE SLSC PROJECT In collaboration with Randwick City Council and Coogee SLSC, Allen Jack +Cottier Architects (AJ+C) redesigned the club house, expanding its teaching and events facilities to greatly improve

Revitalising an icon

Built in 1907 at the southern tip of Coogee Beach, the original masonry club house had been extended over time and in 2016, critically damaged during a major storm event. Council’s brief to AJ+C included a focus on youth life saver training, with innovative facilities and flexible spaces for use by different groups concurrently. The sea wall was repaired and the top (street) level redesigned to create a flexible main training/function room with increased capacity and dramatic new sight-lines to the beach, all while keeping within the existing building footprint. The iconic swimmer’s clock and classical-style portico have also been restored. Future-focused facilities The new interior solves critical access, capacity, and operational issues by replanning the space and relocating ‘back-of-house’ services from north to south within the building. A new commercial kitchen for catering, full-service bar, storage and offices now occupy the southern wing, leaving a central open room that increases capacity from Summer 2022



60 to 200 people, and delivers dramatic new views north to the beach, east to the ocean. The previously pigeon-holed northern wall is now a large window wall, dramatically framing a view of Coogee Beach. Importantly, a new platform elevator from the street entry gives the club house full wheelchair access for the first time. Services have been gathered up into a 35-metre joinery wall along the western perimeter. Pivoting plywood panels conceal two serving stations, storage rooms, WCs, AV technology and egress doors. They also conceal three stacked bays of acoustically-rated retractable walls that partition the open space into four smaller rooms accommodating multiple user groups at once. The only visible service area is the main bar, featuring mirrorbacked glass shelves, an island counter in white Corian and a contemporary chandelier by Australian designer Ross Gardam. Materials and finishes throughout the space echo



FEATURED ARTICLE the coastal location. The birch plywood panelling lends a warm sand tone against the charcoal of carpet and tiles and sky blue of the retractable walls. Club memorabilia, artefacts and honour boards have been integrated in the interior, and the Club colours are expressed in the entry mosaic-tiled and a new Club logo and roundel. “Redeveloping this Club house was a very big dream of ours. The biggest design move was creating a new sightline to the sand with a wall of windows, which we made overt by framing it like a camera. With all its windows and doors open, the top floor becomes a veranda, with views to both beach and ocean.” – Michael Heenan, CEO, Principal Design AJ+C Externally the changes include a new verandah off the east elevation offering a wide ocean deck with views north and south to the beach and cliffs. The repaired sea wall is extended to improve access around the building base. The building façade combines durable materials of varying textures and types: zinc cladding to the north façade highlights the beach-facing ‘camera lens’, while a curved wall of blue-and-white mosaic tiles distinguishes the street entry in Club colours. The

restored clock has been reinstated to the new north facade. “The clock is critical. It was donated to the Club years ago and has a very sophisticated mechanism. It’s the clearest surf clock anywhere on the coast, and locally famous because you can see it even when you’re swimming quite far out. It’s special to me because I swim this bay every morning.” –Michael Heenan, CEO, Principal Design AJ+C Accessible and Inclusive A critical reform is the new platform elevator from street entry to all levels, giving the Club house wheelchair access for the first time. The new sight-lines to the beach from the north window and east balcony offer another Club milestone, now enabling people with physical disabilities to become life savers and participate in patrols, and be in radio contact from the Club house to life savers on the sand. Coogee SLSC is set to become the pilot site for a state-wide initiative training surf life savers of different abilities for other clubs around New South Wales.

Sustainable Key to the sustainability strategy was retaining as much of the existing building as possible including the brick base and external walls. For operational sustainability there are: rooftop solar panels to provide power; low-E glass to reduce heat intake; fully operable doors and windows to deliver natural ventilation; water and energyefficient fixtures and appliances. “After nine months, with the scaffolding now down and the rebuilt Club visible, we couldn’t be more delighted with the design by AJ+C. This is an iconic new clubhouse for a new generation.” Mark Doepel and Tony Waller, Coogee SLSC Key features • Increased capacity of training/function room from 60 to 200 people. • Acoustically rated operable interior walls dividing the space into separate rooms. • Integrated AV technology for training. • A 35-metre wall of joinery concealing storage, bathrooms and acoustic walls. • Platform elevator for wheelchair access to all levels. • New north window wall and east-facing verandah for breathtaking beach and ocean views. A community base for: • Over 620 trained volunteer surf life savers. • Coogee Minnows - Australia’s longest continually running junior life saving club. • Autism Swim Dippers program, for children with other abilities • Annual Coogee Island Swim events (April & November) • Special events venue: weddings, wakes, parties, corporate training etc. • ANZAC Day memorial service, attended by around 15,000 people annually.

Handrail Profiles by Howard Moutrie


ince 2010, AS1428.1 permits handrails to be round or elliptical, though for many years, only round handrails were permitted. Is this restriction valid and can other shapes be just as functional? Firstly, lets look at how handrails have developed. Traditionally they were made of timber, were square or rectangular in shape with a rounded top. See the typical profile in the image below. Much of the bulk of these handrails was for structural reasons – to span between supports and to withstand the horizontal forces which may be applied.

With the increased use of steel, pipe handrails became popular, particularly in non-residential buildings. The use of a circular section makes sense - looking at the profile of a gripping hand, see below, it can be seen that a circular shape results, particularly at small diameters, but it can also be seen that at larger diameters, a more elliptical shape is formed. But steel or timber 16

doesn’t easily form into this shape, though extruded aluminium does. Architects often like to use a minimal flat horizontal section, but under AS 1428.1 these are not permitted. Is the restriction of the profile to circular or elliptical valid?

The handrail has 2 primary functions, firstly as a guide as a person moves up or down the stair or ramp, and this may include a pull-up function when ascending a stair or ramp and secondly, it can be used as a stabiliser when a loss of balance has occurred. The latter requires a higher level of 'gripability'. Templar, in his book The Staircase, suggests that in this latter condition it is important to provide as much hand area to the handrail as possible to avoid tissue damage and discomfort and thus handrails with elaborate mouldings are undesirable. Maki and Fernie, in their research concluded that for the elderly, or people with reduced wrist and forearm function, a handrail with a wide flat upper surface may limit the amount of force that can be applied and thus is not ideal. Templar also considered the handrail


TECHNICAL INSIGHTS with respect to injury from hitting it during a fall but acknowledged that recessing the handrail to avoid this issue would not be suitable for people with disabilities. In the end he concluded that a 38mm round handrail is most effective for gripping but is not the best shape to push away from or for injury reduction. More recent research published in 2009 by Dusenberry et al, found “the most important feature essential for functional handrail profiles are protrusions, or lips, that create finger purchases into which users can place fingers and thumb when grasping both sides of handrails.” Their research found that while the commonly used 51mm round handrail was functional, handrails did not have to be round to be functional. They concluded that “symmetric handrail shapes that are at least 32 mm (1- 1/4 in) and not more than 70 mm (2-3/4 in) wide, with a height above the widest portion of the profile not exceeding 19 mm (3/4 in) are sufficiently graspable as long as there is a recess on both sides at least 8 mm (5/16 in) deep. Each recess should achieve this minimum depth no farther than 22 mm (7/8 in) below the widest portion

of the handrail and extend down at least 51 mm (2 in) from the top of the handrail. Additionally, the portion of the height of each recess that is at least as deep as 8 mm (5/16 in) should be at least 9.5 mm (3/8 in). In all aspects tested, the probability of loss of grip on a handrail with this shape is essentially the same as or better than for a 51-mm (2 in.) diameter round shape.” They also determined that a wider, flatter handrail tended to reduce the impact of the handrail support tending to break a person’s grip – the narrower the handrail, the greater proportion of the handrail width would be taken by the handrail support. So, considering this research it would seem that a wide, flat bar would be a suitable handrail, though not permitted under AS 1428.1. I note that this research was published after AS 1428.12009 was written and thus was not considered. In 2002, Nagamachi et al, published Japanese research aimed specifically at the elderly. This is important research because the elderly tend to be more reliant on handrails, but we need to also consider that people in Japan tend to

Summer 2022


TECHNICAL INSIGHTS be physically smaller than those in Australia. With respect to the size of the handrail, they recommended a diameter of 35mm and that a larger diameter my not be graspable by the elderly if attempting to arrest a fall. The research also found that many of the subjects found that a handrail height of 850mm too high. What do other Standards or countries require? The latest ISO Standard, requires a maximum dimension of 45mm and a minimum dimension of 32mm in any direction. It permits a square shape provided that the corners are rounded to a 15mm radius. Thus, at its smallest the handrail would be essentially circular but at its largest a 15mm flat section would be possible. As there are no commercially available sections, that I am aware of, that meet this criteria, this would be limited to timber handrails. The American Standard permits a square/rectangular handrail, within dimensional limits, and requires the edges to be rounded (but there is no specified radius). This permits commercially available sections which tend to have a 2-5mm radius on the corners. The British Standard is similar to the ISO Standard but does not specifically indicate a square profile, just


round and elliptical. Finally, the GATES Standard or Guide requires a circular profile 30-40mm in diameter or a non-circular profile with a maximum width of 57mm and a total perimeter dimension of 100-155mm. Interestingly, the GATES Guide shows an elliptical handrail with a vertical orientation, which the research would suggest is the least preferred option for gripability. So where does that leave us? It seems to me that like most things there is no single answer. Certainly, using AS 1428.1 is a safe option, but consideration of other sizes and profiles is possible and not unreasonable. I certainly don’t think that rectangular profiles should be excluded as the research seems to support their use. It is obvious that the size of the handrail probably should consider its context, for example, in seniors housing a smaller handrail than in a public building, but there is sufficient evidence to suggest that the ”standard” 50mm diameter is in fact too large for circular handrails and a size of 30-40mm is more graspable. This goes back to the photos earlier in this article of the hand profile.
