The house has too much depth. More width (and less depth in return) would create better rooms.
I find the kitchen terribly difficult to furnish, far too elongated. That won’t work for a modern kitchen with an island. At least I would close the direct pantry access or, if it absolutely has to stay, position it centrally in order to be able to place the kitchen along both long walls. But even that wouldn’t appeal to me personally.
The office upstairs is really a mess. It’s just a storage room, but unnecessary because of the basement.
The living room is also hardly furnishable. You can already see that from the tiny sofa drawn in. How are you supposed to place a proper L-shaped sofa for a family of four there and simultaneously orient it toward the TV? Also, the sofa is in front of a floor-to-ceiling window. What’s the point of that?
The bay window may look nicer from the outside, but it doesn’t bring any added value inside the house. On the ground floor it will probably just be an expensive corner to put flowers in, and the strange corners in the children’s rooms are also unusable. The bay window is an expensive indulgence.
The staircase right next to the door is also a matter of taste.
I would also miss space for a wardrobe.
Upstairs, I would at least access the dressing room from the hallway. Remove the door to the bedroom, center the window, and position it so that furniture can be placed on both sides. As a proper dressing room, it is too small anyway; it’s more like a closet room. And if the closet is outsourced from the master bedroom, I find that room already quite large.
I would really like to see the upstairs bathroom in person.
So, I don’t like it at all. There is something to complain about in every room. That’s why I would start over and give the house more width. I don’t know whether the plot allows for that.
