150 sqm detached house - demolition & new construction - recommendations?

I don’t like the floor plan. The ground floor is okay, even though space is wasted by two staircases. But upstairs... The L-shaped children's rooms... the "walk-in closet," which just looks like a leftover passageway to the bathroom and what on earth are we supposed to do with it?... The shower under the sloping roof... This has to be done better. It seems to me that the interior staircase is the problem; it somehow ruins everything.

The two staircases must go. The south terrace is nice, but the garden access is missing, especially for children. The house entrance in the north is no good. Your visitors have to walk all the way around the house and thus gain access to the private garden. I would place the entrance in the east, with kitchen, living, and dining areas with a terrace more to the west. On the upper floor, the two-meter line is not taken into account. Shower under the slope, no tall wardrobe in the parents' area. Children's rooms are dark; provide side windows, especially because of the shading. The house needs a different staircase, different orientation of the rooms.

Thank you very much for your comments.

In the current existing house, the entrance is also on the north side. You walk west past the house. To the east there is currently a garage (the house is marked on the development plan, which shows this; the new house is supposed to be in the same place). We actually quite like this option, we don’t have to hide the garden. It is primarily intended for planting and as a play area for the children. The outdoor living area for the family is mainly on the terrace. Access to the garden could be realized from the terrace to the east past the house, something similar is done in the existing building as well.

Regarding the stairs: we originally had a design with stairs stacked on top of each other leading to the basement and the upper floor, but we didn’t like that. We want an open staircase to the upper floor, which we do not want to hide in a stairwell. For the basement only a closed staircase is an option because it will not be heated.

At first we also thought about “saving space” with the stairs, but we now see the staircase more as a “design element” that can be shown. In addition, I find the open space under the stairs good for our dog, children’s toys, etc.

We want to mainly orient the windows to the south and north, since to the east and west you only see the neighbors. We’d rather enlarge the windows at the front and back than have more on the sides.

The knee wall on the upper floor is 1.20 m, so at most a roof window can be installed in the children’s rooms, which however is again not good for the photovoltaics.

Some women need a lot of closet space, but currently we have together a 1.80 m wide closet (and no basement or similar storage room). The dressing room (walk-in closet would be the better term) plus the closet next to the bed is actually completely sufficient; if not, there is also space for dressers under the window and opposite the bed.

I am still not happy with the shower under the sloped ceiling in the bathroom, I am open to new ideas here.

But that’s quite nonsense, isn’t it? Why have a house? A large plot? You have no connection to the garden at all, sitting cramped by the street...

Only a closed staircase is an option for the basement, since it is not to be heated.

I think that is definitely not compliant with the energy saving regulations...

You are still young, don’t have children.
Believe me: that will all increase, you have to store a lot. Your wardrobe is just enough for the household laundry of a family.

Personally, I find the private entrance situation limited by the utility room, the office too small, and the dining area in the entrance corridor with the restless stair view and situation more than uncomfortable.

Why don’t you put the garage next to the house and use the basement?

Having no view or access from the living area to the play area or shaded garden is more than unfortunate. The sandbox season never ends in winters like these. You don’t build a house to feel like you’re living in an apartment.

There is a lack of light. This is not about the maximum feed-in tariff or the view of the neighbors. The house gets dark and the children’s rooms could be sublet to vampires.

yes, it is a sin to equip a ground-level south-facing location with a garage. Apparently, the car is very much loved here. The garage is almost like a hall.
