Floor plan design single-family house limited size

I also doubt that the staircase with the superstructure on the upper floor will work properly. And the two small utility room niches may not be so great for the technology either.

So, there are quite a few issues.

I also cannot see why the house is exactly limited to that size.

We are only allowed exterior dimensions of 114 m2.

Who says that? Where does it say that? How can you tell?

Personal price limit for the house, including equipment: 400,000

That only allows for about 120-130 sqm.

Although there are still some DIY options there.

DIY is quite ambitious. Where do you get the strength for the muscle mortgage?

I am happy to help on the slope. But heights just like that without any reference won’t work. Please mark the property and the building site on the height plan. Where is north? Where is the street?

I am planning under 114m2, which is easy with a gable roof.

Chief Inspector Sven Hansen would say: "we once had a case in Hamburg ..." (but if I remember correctly, it was 117 sqm) (?)

I have contacted the OP via messenger and real PM and am leaving the altri Egi (I hope the plural is correct, my Latin is ages ago) among whom we presumably already know him here just like that. The situation is, if I remember correctly, complicated to the fifth power.

The room layout is quite unusual. I would definitely not build it as the plan is drawn. But: The idea of two "En-Suite" bedrooms has its own charm. If you take modern hotel suites as a model, you can save a considerable amount of hallway and some walls. It should be taken into account that these solutions generally offer little storage space. There is no rule that says the access to a bedroom with an attached bathroom cannot be through the living room area. Some "runways" may possibly be longer than in a usual "central hallway concept," but the usable space can be increased on a small floor plan. The architect is likely to enjoy thinking outside the box if it fits your lifestyle.
