There is a large Canadian grocery chain that has taken to putting the parking underneath the store. There is a ramp accessing the store, as well as an elevator.
The elevator is a wonderful idea however, the design leaves someone who is mobility-challenged, challenged. The problem arises when you use a shopping trolley. In order for the doors to close, you have to push, drag, slide or pull your trolley over. This is not a problem for someone who is able-bodied, but then, if you were able-bodied, you'd have no problem using the ramp.
When your mobility is compromised, you may find it difficult to push a cart up the ramp or to hold on to it on the way back down. The elevator is the wise choice, you'd think.
The solution is simple. Make the elevator deeper so that the trolley can easily be pushed straight in to the space. No awkward manoeuvres that are so difficult for someone who is already struggling to get through life independently.
I have written the company a number of times, to no avail. Perhaps you'll take up the pen or keyboard to elevate this idea to the status it deserves. One that is truly accessible.
