It is so rude ... where is the problem with placing a north arrow on drawings, then you don't have to interpret "where the entrance is, that's north," it can be to the right on the plan, it can be at the top of the plan, etc.
And, a site plan with a few dimensions would also be good.
Otherwise, I can only agree with Katja, first furnish to scale, both living areas as drawn are not usable and the parents' area is really oversized at 40 sqm.
