hello, first of all thanks for the numerous responses. 1. we have decided against a storage room because we store drinks in the basement, all other food should go in the kitchen. we will install a central vacuum cleaner in the basement, the system should be such that the suction hose disappears into the wall. honestly, we haven’t really thought about cleaning supplies yet, they might find a place in a cabinet at the wardrobe. 2. I will think about the dressing room again, we would just like to have 2 wardrobes so that each has their own. 3. in the basement there will be a large hobby room, one storage room and the room for technology, washing machine, etc. 4. regarding the stairs and the kitchen, I agree with you, I will try to get the stairs to 2.16m wide, 2.25m probably won’t work because then I lose too much width in the living room and guest room/office. I would like the kitchen to be 3.60m wide, I think that will work better (row 60, distance to island each 1m, island 1m) 5. we have decided against a children’s bathroom 1. because of the costs 2. otherwise we would have 3 bathrooms on the ground floor, which already has a shower. 6. what I don’t quite understand are the comments about the living-dining area. the length will be 9.50m and the width 4.45m I actually thought that a width of 4.45m is wide enough so that it doesn’t become so tube-like, or exactly what bothers you about it? for furnishing we thought of a living room wall on the wall towards the stairs, plus a corner sofa about 3-3.20m wide (we often have many guests) and in the dining area a table for at least 6 people, in my opinion there isn’t much space left between the sofa and dining table, right? it shouldn’t all feel too cramped. about the roof you are of course right, it will be a tent roof. I also don’t like the windows yet, I think they don’t look very modern.
