I just asked him now why he doesn't ask the council to do it and he said that he has asked them in the past to put the ground floor w/c in for him but they rejected his request because of some rule they have about working on a house that does not have a level access (apparently the door step on the house that is about maybe 15cm high makes it so that they will not work on putting a downstairs w/c in) he also asked them to then remove the door step and then come and do the w/c (he is in a wheel chair so removing the doorstep is actually something that he needs to be done to help him get in and out the house anyways) and they refused and basically told him to go on the register for a house to rent that was disability friendly...I have seen a lot of new bathrooms and toilets paid for by the local council for disabled people!
Could you not just swap the access point on the existing SVP for a junction and run into that?
