Is tawaaf permissble on the wheel chair. Also they do not allow the tawaaf on wheelchairs nowadays down. There is an area up for wheel chair people, is that permissible.

Yes it is permissible on the wheelchair, but the person himself has to move it not someone else. However, it must be from ground level. If one does it from the second floor, he had to ask someone to do it on his behalf from the ground floor.
