I am building my in-laws a small elevated decking, only up about 0.7 M (about 4 X 3 M) out the front of their unit in an already roofed area. As my father-in-law is a bit slow and getting on a bit i need to build a ramp instead of steps. He used to love his gardening and a place to sit and see it will make his life much better. He can walk, well shuffle, is able to navigate steps now but who knows what he will be OK with in the future.
I need to know what sort of gradient it will need, there will be rails down down both sides and about 0.9 M wide.
Want to run it off in a straight line in-line with front door as this will make access easier for them, but I am a bit restricted for area for ramp.
To go this way I will have about 1:9/10 gradient to work with, is this too steep?
Have been told that wheelchair access has to be 1:12, is this the same for old people ramps?
