Maybe, one way of addressing this vexing challenge is to look at things as 'What does it cost to convert a building afterwards, as opposed to applied to the original design?' This may well not be the way many prefer looking at this issue, but it certainly makes those footing the bill, think twice! Other than the additional equipment such as rails and more specalised pieces of 'kit', locating something in a different position to the 'norm', (eg light-switches) isn't any more expensive, whereas changing the width of a door, afterwards rather than during the original build, is monsterously expensive, whilst the cost differencial between wider doors than normal width ones, (whatever they are!) might result in a variation of 1-2% of the total cost. ----------End of Message---------- Run by SURFACE for more information on research, consultancy and the distance taught MSc. in Accessibility and Inclusive Design programme visit: http://www.inclusive-design.it Archives for the Accessibuilt discussion list are located at http://www.jiscmail.ac.uk/lists/accessibuilt.html
