New single-family house ~160m² + basement - first draft

Knee wall & roof slope unknown - therefore no concrete tips possible.

It should be 1.50m knee wall and about 40° roof slope.

The toilet drains do not work at all. Where are the shafts on the ground floor? If you trace them, they are in front of the entrance door and wardrobe. I would definitely plan the dining area larger.

Do the shafts always have to drop straight down directly from the WC? Otherwise, in the corner by the front door, then the guest room door would have to be slightly moved and from the master bathroom into the guest WC.

With us, the shaft will not go directly down under the toilet and in the old house we didn't have that either. That's why I say no, it is not necessary.

In our case, the shaft does not go straight down right under the toilet, and in the old house, we didn’t have that either. Therefore, I say no, it doesn’t have to.

But it is better. If something is newly planned, then optimally. This is the most sensitive issue: anyone who has experienced a pipe clog is thankful when there is no bend in it. Clogs hardly happen without a bend...
Please also check the cabinets under your refrigerator as well as the showers that are too narrow. Shell construction dimensions show no mercy when it is too small for door frames next to a shower. There is also no wardrobe in front of a 1.50 m refrigerator.

Please also check the cabinets under your fridge as well as the too narrow showers. Shell dimensions show no mercy when it is once too small for door frames next to a shower. In front of a 1.50m fridge, there is also no wardrobe.

In the upstairs study, there should be a chest of drawers next to the fridge. In the bedroom, there should be a built-in wardrobe with a slope. It is, of course, not optimally drawn in the floor plan.

The shower in the children's bathroom measures 80x100 and in the master bathroom 90x120.

What is the moral value of adopting the external dimensions of a maxim?

What is the moral value of adopting the external dimensions of a maxim?

Actually none. We have our first appointment on the weekend with Viebrockhaus and I wanted to present it there. If we end up with a local construction company, of course it's different.

But we like the size itself, hence the "basic framework" as it currently is.
