The Singapore Government’s Building and Construction Authority has a section on universal design guidelines. It has three key guides as well as other related information.
The 2016 Universal Design Guide for Public Places is a good practice guide for the built environment. It’s been well thought out and is presented clearly with many illustrations and drawings. This is a comprehensive guide that goes beyond basic accessibility requirements of previous guidelines.
The 2007 version of the Universal Design Guide has more detailed information including residential as well as public buildings.
Scope Home Access has developed a Home Modification Assessment Tool, which is mainly for specialised home adaptations, but there are some useful mainstream ideas, particularly for ageing in place. For older people who are thinking ahead about how to stay put as they age, the checklist, although long, does give some good things to think about. However, not everyone wants to think ahead to a time when they might need these designs. That’s the problem.
The tool is good for builders who want to know what to think about in their designs for client renovations. There is also a health and ability checklist at the end. It is the kind of tool best used in conjunction with an occupational therapist.
