Floor plan single-family house approx. 135 m³, floor plan. Garage, 1.5 stories, 4 persons

Would you build with KSPE, or with "normal" bricks? Collar beam ceiling, or in-situ concrete ceiling?

What is KSPE? Please speak in full sentences and not as if we could read your thoughts.

I really like the floor plan. The location on the plot is sensibly utilized, and the room layout is similar to ours on the ground floor.

The plot as well as the ground floor immediately reminded me of your house .

A straight staircase can unfortunately often be difficult to combine with efficient floor plans.

The single-flight straight staircase is a curse for (and not infrequently also through) a floor plan. It should by no means be among the mandatory requirements for the designer.

Hello everyone,

thank you very much for all the comments and ideas.

[*]The wardrobe should find its place under the stairs.
[*]The maximum eaves height is limited to 4.2 m according to the development plan, which means we cannot go higher with the knee wall.
[*]With the straight staircase, I lack the imagination of how to change that without having to make the house wider on the ground floor.
[*]KSPE: Prefabricated wall kit made of sand-lime brick - Lego/Tetris for adults

Best regards

Would you build with KSPE, or with "normal" bricks?

Build with the material that the builder uses and that makes the most sense regionally. Regarding the house: look at the mentioned bottlenecks. They are: bicycles/cars in the garage, utility room, cloakroom, and bedroom/bed height. With 1.20 KS you get an interior knee wall of about 130 cm. Currently, you have 100 cm inside. So there is a capacity of 50 cm. There is also this buffer in height. I would definitely increase one brick size and make full use of the heights. The attic would also gain standing height then. That is important for storage space, as some things would mold in the garage. It may be that some of this is because a structural engineer made the design and not an architect. If you have your wedding photographed by a photo lab technician, you probably won’t get the professional and design quality that a photographer provides. The space under the stairs is enough for a nice big dresser, unfortunately not for a wardrobe where everyone can keep their jackets and coats. The passage door between garage and utility room takes up valuable space on both sides. Maybe you can already plan a fixed emergency staircase from the upper floor to the attic. I would also modify the windows: sometimes a patio door instead of a window doesn’t harm the ground floor. For storage on the upper floor, I would skip a window. Edit: I probably confused eaves height with wall height. Be that as it may: the planner should figure everything out.

One builds with the material that the BU uses

Here with the search term "11ant Steinemantra" and externally including the quotation marks as "Das Steinemantra des 11anten".

Edit: I apparently confused eaves height with wall height. Be that as it may: the planner should figure everything out.

Since they are synonyms, they cannot be confused in content. Wall height is the neutral term, because pedants might otherwise consider the parapet of a flat roof as not affected by the rule. Caution: the "self-chosen" upper edge of the finished ground floor slab is not always identical to the reference height!

As far as garage/carport/parking space is concerned, everyone has their own ideas. Here in the forum, carports are often praised. I enjoy my well-tempered car in the garage in summer and winter. That is to say: the OP must have had a reason for this solution, I assume.

I count myself among the cheerleaders. The reason for this lies solely in the significantly higher costs for a nice garage, and if for a sometimes "well-tempered car" (which my electric car, by the way, also manages via the app even in the parking lot) I had to forgo important or nice things INSIDE the house for budget reasons, I would consider that a misalignment of my priorities. In my "human house," I could imagine many nice things first before implementing them in the "car house." An air conditioner, for example, is practically in every car but only rarely in the house. Omitting the garage would enable this, for example, as well as blinds, controlled residential ventilation, beautiful window fronts, nice furniture, and much more; the car would come far later. But everyone decides that for themselves; only the sometimes-made statement that there was no money for this or that does not apply, because the money was simply spent elsewhere.

The max. eaves height is limited to 4.2 m according to the development plan, which means we cannot go higher with the knee wall.

In this case, the upper floor is boxed in or, for example, built-in wardrobes are placed behind the bed. Either way, the bed must be noticeably pulled forward below the slope and moved to the center of the room. If there is not enough space for that, you have to build bigger. And before you buy a different bed now - no, that is not a solution either. Otherwise, you will constantly bump your head on the slope.

The wardrobe is supposed to find its place under the stairs

Not enough for 4 little people. Conclusion: Your first draft is already quite good but not perfect yet. The little mistakes still have to be fixed.
