Hello Planner,
first for the sketching: I would always sketch with a site plan. Has that already been done?
You write that the access road or street location runs to the south. So the garden is in the north, or is it more to the west or east? The rooms should be arranged accordingly. From where do you want to look into the garden? Sofa position?
The common standard building plan does not always fit the property. I mean to say that there are also possibilities, e.g. here to swap the kitchen with the office (one of several possibilities of these standard plans).
Since you are overwhelming us with little information, we can only give superficial tips. Whether your dream house will result from this on your property, I doubt.
I have posted something as assistance.
It would also be helpful for you to read other already discussed floor plan topics, then a lot will become clearer to you.
I would also like to discuss the following considerations:
1) Does it make sense to remove the kitchen door to the hallway (more storage space)?
That depends entirely on the living habits. For example, we have everything open. However, since it can already be seen that you prefer closed construction, I would favor a door so that the frequently used path to the kitchen (e.g. from the entrance, basement, or mornings) a) does not lead in a circle (living room door and then 180 degrees back) or b) in the evening always passes by the sofa where someone in the family might be seeking quiet (children come by with their teenage friends in the evening and want to grab a snack from the kitchen or even linger there).
If, however, the room layout is designed so that the sofa corner is out of the kitchen's view, then you can also do without a separate kitchen door and enter the main room through a dining door.
2) Is the sliding door to the living room sensible? It should close tightly (because of smells / noise). Is this even possible?
In my opinion, it is not possible to isolate extreme cooking fumes from the rest of the house. Cabbage, fried food, and fish linger in the air for a day anyway, the kitchen door is sometimes opened, and besides, I know no door that has no gap at floor level (necessary with controlled residential ventilation anyway).
However, I ask myself why one should not constantly be surrounded by the delicious cooking aromas :)
3) How many windows are sensible?
Basically, every living and common room should have a window. Daylight is important for body and mind and also for electricity costs. The size of the windows: in the past, 1/8 to 1/10 of the room in sqm of window area was considered standard; today, windows are planned somewhat more generously. However, it is hard to generalize because the location of the rooms also plays a role. Surely a living room facing north needs more daylight than a room facing south because the light quality is different.
And of course, it also depends on your own preferences whether you equip the long living room wall fully with windows or with two small loophole windows. That would also come down to the building style...
4) Are the hallways too narrow?
Hard to say from a sketch. Nobody wants to slalom around some dressers. In your sketch, I don’t even see the possibility of a wardrobe. Surely the niche at the end of the (current) hallway would be an option, but actually already too far from the entrance, then too close to the living room, and basically this hallway extension is over anyway.
5) Is there too little space at the upper stair landing between the stairs and bathroom (e.g., if you want to get a larger piece of furniture around the corner)?
hmm... everything over 1.30 m would probably be okay. Nevertheless, you are currently at the shell construction measure.
Regards Yvonne
P.s. and always draw in the furniture again so you know whether you always have to go around or past the sofa and whether the dining area can work. Bedroom: does the bed and the wardrobe fit...
