Hey thanks for the response, unfortunately new here and couldn't continue writing the question, apparently there is only a limited number of characters, but I think where I wrote "hi" the question or details will go in.. Sorry for that.. Yes bungalow and filling up are about 3.5 m height difference and the building line stops after 20 meters, meaning if the house is 14 m long, you only have about 6 meters to ascend, so the garage will be quite a steep thing then
