My impression:
Half of everything would still be good.
- Someone has to clean all of that (want to)
- On the ground floor, the storage room is almost as big as one of our kids' rooms,
- The guest WC has room for a whole sauna, just imagine sitting on the Locus, how lost you feel in the hall of the guest WC, except: you are a true mydealzer and are involved in every "TV for guest WC" and SNES Mini deal
- Cloakroom: it can be that big, you will definitely fill it well, but that also applies to one half its size, you just collect and don't sort out or put the winter jackets in the summer in the basement under the stairs (where a cloakroom would also fit)
- The size for the living/dining/kitchen area would be okay, I would hide the kitchen in an L-shape of the whole room to do something good for the acoustics
- I was happy about my big kids' room, but I think it was almost 20m² including the sloping ceiling, if the kids' rooms had 16-18m² of floor space that would also be very sufficient
- The size of the bedrooms results automatically if you reduce your ground floor area
- I also find the rooms very quirky with many corners
- impractical because you can't place anything properly and there will also be great difficulties during interior construction (painting, flooring, baseboards), to not waste any space, I would arrange the rooms in the four corners, align the stairs centrally and then see how the stairs fit on the ground floor and possibly rotate the rooms etc. there
- possibly give the stairwell a "gallery". Rather unused space, but better than puzzling it in everywhere else. Besides, the hallway becomes a bit more livable this way.
- I like the idea of a fixed staircase to the attic
- Consider a heating method for the attic, at least as preparation
- In the basement, I see two cellar rooms that seem poorly usable, a small but possibly sufficient utility/storage room (HAR) (ours is 2.5 x 1.2m and is 70% used up by the large heating system, fuse box, and connections but you can reach everywhere well)
- As in the attic, the room layout and walls seem unsuitable to me
- The almost alcove is furthest from the guest WC in the basement, rather an unfortunate distribution of rooms
- The hobby room is very large, do you already have an idea what you want to do there? It could become a second living room, so that not only a home trainer goes in there and the rest of the room is only for cleaning.
- If the house were smaller, the hobby room could also give up quite a bit of space
- On the exterior views, the windows with their different sizes and shapes look like Klitschko after his last fight, I would also pay attention to symmetry here
- I don't consider roof windows useful, for example we installed double-wing windows (1.5m - 2m wide with frame) so that a lot of sun comes in, sunlight is important to me
If you are not offended by me (I was quite blunt), I suggest the following:
- start drawing again from the beginning
- start with simple room layouts
- rooms should have four walls if possible (or more in L-shape, but no niches)
- design the rooms as small as possible!
- place stairs and entrances and shift rooms if necessary
- if something doesn't quite fit, enlarge the outer walls of the house a little, which will "accidentally" also enlarge some rooms
- if everything "fits" now but is maybe too small, you already have a good floor plan, you can now extend your outer walls further to enlarge all rooms
- set windows and think about symmetry from the outside
This is not a patent recipe for a "beautiful" house but prevents a mess.
If there are special design wishes for rooms or other things, they can be incorporated at any time.
Otherwise, if this is not your style: talk to several builders or architects, they also make offers and listen to your wishes beforehand. The offer then includes floor plan drawings. All this is free for you. And you get various ideas from the professionals.
You can lay the offers side by side and compare them with your ideas.
