Single-family house - flat roof - forest edge location - 175 sqm

In addition, I want to have the morning sun in the kitchen and the evening sun in the living room

Hmm ... in summer, however, the evening sun comes more from the direction where you then have no windows in the living room, and in winter the west sun is gone before work is finished. What also surprises me is the suggested sofa position. Kitchens almost 5 m wide typically call for a real kitchen island and not a peninsula. Otherwise, the kitchen is for big traffic areas. Here's an example from a kitchen planning that immediately came to my mind. Including utility room next to the kitchen ... given the position of your stairs, I would probably prefer the access there as well, since the stairs are supposed to come down in the kitchen. ------------------ Is the garage actually supposed to have a walkable roof? ----------------- Master bedroom ... I don’t think the bed position with the headboard next to the passageway is good. ----------------- Children's room ... super large floor-to-ceiling windows like that should be seriously reconsidered, they limit the ability to furnish. Children also become teenagers, so always check the furniture layout, including the popular teenager bed size of 140 cm width.

Since you are building on a slope, I would try to equip one or two rooms with windows and thus make better use of them. In my opinion, the bathroom is a disaster. Kitchen with terrace doors is not necessary, purely a matter of taste.

Correct. It is planned to equip the basement room in the southeast with a strip of light.

I see the floor plans changing again as a whole: I would describe the ground floor as "inefficient": the ratio of few room functions (only living-kitchen, utility room, WC, and circulation area) to a lot of space (67 sqm just for living-kitchen, and if the total area were less generous you would more quickly see which space eater the straight single-flight staircase is) is costly without compensating for it.

You could reduce 20 sqm on the ground floor overall without missing them. Then I would position a two-flight staircase roughly where the bathtub and shower are now, with otherwise the room layout remaining the same.

Attached I have highlighted in color where exactly the difference between the ground floor and upper floor area is. About half of this surplus would also benefit the upper floor, i.e., from my point of view, making the difference between a storage room for a double bed and a bedroom.

I would not see a "loss" of profiling of the building form in the sense of the pseudo-Bauhaus effect ("wild" cubism) in a dramatic way

I will cautiously rephrase "inefficient" as generous. But you are right. We do not need more rooms on the ground floor. Sure, the house could be shortened by 1 m so that it becomes 10 x 10 m. During the week I am quite busy, but I will try a half-landing staircase.

Regarding the projection also on the upper floor: It might become structurally quite complicated if the corner glazing is to remain, right? Whether this is a "storage room" or not, I also see more as a matter of taste. Since we are only here to sleep and the laundry is stored in the walk-in closet, there is not much more than a bed and two nightstands in the bedroom.

The house was never aimed at wild cubism; I prefer energy efficiency and still realistic acquisition costs. I just like clean lines.

Hmm ... in summer, however, the evening sun comes rather from the direction where you then have no windows in the living room, and in winter the western sun is gone before work is finished. What also surprises me is the suggested sofa position.

Almost 5 m wide kitchens actually call for a real kitchen island and not a peninsula. Otherwise, the kitchen is full of long distances. Here's an example from a kitchen plan that came to my mind immediately.

Including utility room next to the kitchen... given the position of your staircase, I would probably also prefer the access there as the stairs are supposed to come down into the kitchen.

------------------
Is the garage actually supposed to have a walkable roof?
-----------------
Parents’ bedroom... I do not like the bed position with the headboard next to the passage.
-----------------
Children’s room... one should seriously consider such super-large floor-to-ceiling windows, they limit the ability to furnish. Children also become teenagers, so always check furnishings, also check the popular teenage bed size of 140 cm width.

I have attached a screenshot of the sun’s path at 8:00 p.m. in midsummer. It clearly shows that we still get sunlight in the living room. Regarding the sofa position: Because with the back to the window?

Thanks for the note about the free island; I will immediately try playing with the position. I do not understand the comment about access to the utility room?

Walkable roof depends on the costs involved and whether it is permitted. Of course, this would be a nice breakfast spot in summer. However, I could also do without it.

Beds in the children’s room or room 2 are all drawn at 1.40 m. If I made the window a bit narrower, what could be changed in the positioning? Currently, only one child is planned.

I hope I was able to address all your questions and suggestions. Of course, I will keep you updated on further optimizations. Gladly more criticism.

I’ll cautiously rephrase "inefficient" as generous.

No, that’s not "cautious," that’s blatantly talking nonsense. It would be "generous" if the surface created a sense of spaciousness. But it doesn’t here; it evaporates the moment you pay.

I just prefer clear lines

"Emphasized horizontally" would be more accurate than "clear" in my opinion.

Whether this is a "storage closet" or not, I also see it more as a matter of taste. Since we are only here to sleep,

A pure parking spot for tired bodies might suffice, if you have the gift to fall into a Sleeping Beauty sleep on command.

Regarding the projection also on the upper floor: It might get structurally quite complicated if the corner glazing is to remain, right?

I usually postpone going into detail about structural engineering to somewhat more advanced design phases. It is solvable, and every client has a different hobbyhorse to which they attribute importance for the exterior of their house.

No, that is not "cautious," that is brazenly babbled nonsense. "Generous" would be if the surface brought a sense of spaciousness. But it does not here; it evaporates at the very moment of payment.

OK, let's ask the other way around. What area for living, dining, and cooking do you consider appropriate if a certain sense of spaciousness should still arise?

A pure parking space for tired bodies may suffice if one has the gift to fall into a deep sleep on command.

Fortunately, we have that gift.

That this ledge has not only a practical use we don't have to discuss. Here everyone, as you say, has their own preference. Let's see where the price goes if one extends it a bit further. I find that hard to assess. I have already asked about the implementation in another thread. The expensive part is probably the thermal break. Whether I add another meter to it and how that affects the cost financially might be explained by an expert or someone with experience.

OK, let's ask the other way around. What area do you consider appropriate for living, dining, and kitchen if a certain sense of spaciousness should still be created?

I already said that: about 20 sqm can quietly be removed there. Approximately 3/4 to living-dining-kitchen and 1/4 to the hallway, roughly estimated.

I am getting back to you with a new idea and would like to hear your feedback on it. The house is now smaller and the ground floor has been recessed into an L-shape. I have moved the staircase to the other wall panel and shortened it to 15 steps. The clear floor height would thus only be 2.50 m.

However, I like the upper floor here much better, as the rooms could be better divided -> larger bedroom with a large walk-in closet, which is supplied with natural light -> appropriate size of the children's rooms -> smaller, cozier bathroom



Where do you see room for improvement or changes here?
