Hi Liam
I feel strongly about this topic as I've become friendly with a wheelchair-bound gentleman over the past year or so. He is an extremely independent person, with his own house/car/job. However, I've been horrified by the impact of inaccessibility in normal day-to-day living. I've seen him having to scoot up the side laneway and take a leak before entering the pub, as he knows the pub has no wheelchair accessible toilet. Quite how he managed to take a leak in a dark laneway, I don't know - & I don't really want to know. And of course, he has no where to wash his hands. I've seen him having to leave a house party after 90 minutes as he would be unable to take a leak without having all the fuss & bother of getting three untrained guys to lift his wheelchair up the stairs (& round the three bends on the stairs) - no mean feat in itself with untrained lifters.
Also, when my mother became ill some years ago, taking her into our home was not possible due to lack of wheelchair accessibility. We had two months notice of her requirements.
It is foolish to say that "The requirement of wheelchair access is not going to be an emergency or without notice" unless of course your personal psychic assures you each morning that you're not going to be involved in a traffic accident that takes away use of your legs (as happened my friend). He had about 6 weeks notice (i.e. 6 weeks full-time in hospital after his accident) that he would need a wheelchair-accessible house. Is that enough time to buy/sell/modify a house?
Comparision with hyperthyroidism, dwarfism, paraplegics seems to be a diversionary tactic. Just because we don't look after these people doesn't mean we shouldn't look after the wheelchair-bound. If we try to look after these people, you can list off another thousand medical conditions that we don't support - Are you seriously suggesting that we should do nothing about ANY of these until we can do them all simultaenously? On a more practical note, I would guess that the number of people wheelchair-bound would outnumber the number of people disabled by any of these conditions, so it is good common sense to look after wheelchair-bound persons first.
And what is the big problem with a regulation that insists on wheelchair-accessible downstairs toilets. Tommy rightly points out the one weakness/loophole that the builders have not surprisingly exploited, but is it really too much to ask that able-bodied persons put up with just a slightly smaller kitchen to ensure that my friend and others like him can take a leak indoors?
