Thanks guys, Just the info I wanted. I think I'll get the frame and
build as I go - good advice as usual.

Hi Tim

It probably doesn't apply to you here, but while it is simpler to build in a
frame as you go, this is only OK for softwood painted frames. Anything
unpainted like hardwood is probably going to get stained and damaged by plaster
and other subsequent work. A temporary frame is the way around this.

Normal wheelchairs will go through a 762mm (2'6")wide door opening but this is
really the minimum if you want to spare your knuckles. A 838mm (2'9") door is
better if you have the space. Legal requirements for care premises require
minimum 800mm clear opening width, so if the door only opens 90° then you need
to add the door thickness and the handle projection!

I do worry about some of the legislation though. Whats the point of
building a doorway suitable for getting a wheelchair through only to
have to have a step down into the garage!!

More not "joined up" legislation . . . .

AFAIK there is no legislation that says the connecting door from an integral
garage into a dwelling has to be suitable for wheelchairs (even though that's a
good idea). I guess the regulations assume wheelchair users will use the main
garage door and then go into the house via the dedicated disabled-access point
if they can't manage the step. The intention of the step is to prevent fuel and
heavier-than-air gases from entering the house causing a fire or a noxious fumes
hazard, so if you have the space it could be argued that a ramp will work just
as well. If the BCO insists on a step then you could ask him about the
possibility of a grant towards a wheelchair lift!
