The benefits of inclusive design and the way it contributes to wellbeing are difficult to measure. David Bonnett writes in a Design Council article that being able to explain the benefits is important. While it is relatively easy to apply inclusive thinking to new buildings, homes, and transport, older buildings are another matter. Bonnett points out that, “Tesco, Sainsbury’s and other retailers will readily justify expenditure on inclusive design by improved retail figures. Regrettably our public health professionals do not yet have a similar cost benefit analysis to draw on”. While the benefits seem really obvious to many, intuition is not enough – it has to be quantified.
