I have not needed the wheel chair accessible toilet in the South Wing of Broomfield Hospital. But reportedly it is on the 3rd floor. I may be wrong but I think you can only use a specific lift (if you can find it) to get to the 3rd floor. This is what comes of adding onto existing buildings, you get multi layers and half layers that can only be accessed via peculiar routes. University of Essex in Colchester has the same issues regards accessiblity from parking to classrooms to the lecture theatre. You need a sat nav to find the wheel chair (no stepped) route to so many places on that campus. It has a serious case of back door entrance only for wheel chair users.

There is a big noise about the accessibilty of the Post office (now relocated to upper floor of WH Smith) in Chelmsford. Sometimes the lift isn't working. Even when it is, it is being used by staff to move goods between floors.

You should print off that list of inaccessibilities in very large font, one to a page on bright neon paper.
Then tack up in corresponding areas of the building you described.
Hey we could all do this and provide a list to building managers as well as the local newspapers and government representatives.
Let's be proactive about accessiblity.
