Single-family house on a slope, floor plan: timber frame construction and precast concrete basement

If the 2m line remains from the initial draft, which I assume due to the roof data and eaves height, then in the upper floor with the WC you are now below this 2m line in the ceiling height area of 150 to 200 cm. In the initial draft, you had headroom for the WC from the double casement window above the WC. That’s why the double casement window was there. Now you have headaches when you get up from the WC.

Yes, we will end up around 1.8m here, the planner will give us the exact info later. But we actually don’t want a roof window above the WC, but rather above the tub, which is now possible. The main WC will be on the ground floor anyway.

The short wall in the ground floor kitchen doesn’t make the kitchen bigger.

Not directly, but visually. We want different floor coverings in the living/dining area and kitchen. This short wall then serves as a visual separation and you can still see into the kitchen. Also, it’s a perfect corner for a telephone cabinet.

And if the idea really is to give the children the basement rooms later, then I would make sure the rooms are roughly the same size. And also design the bathroom there differently, because 195 cm raw construction width for a reasonable shower and a toilet next to it is not so great. Also with regard to a separable apartment, where I would also simulate the separability.

That is correct and also my thought. However, we can’t think of a better solution since the technical room should stay there due to the supply lines, and the bathroom also because of the pipe routing. And enlarging the basement room only to make the other room smaller is not so great either. A 90 cm shower fits in there and then there is still almost 1m left for the toilet. The separability is well possible this way, by putting up a wall between the hallway and guest room and making a wall opening between the two rooms. Or do you have a better idea?

So, we now have the exact measurements from the finished floor: At the toilet, it will be 1.26m to 1.99m (60cm to 150cm away from the exterior wall). Sounds little, so we tried it out right away. It should be mentioned that we will have exposed rafters on the upper floor, the heights refer to the underside of the rafters, which are 14cm thick.

The practical thing is: We currently have exactly the rafter width, the spacing, and the roof slope in our apartment, so we were able to test it perfectly. And I have to say: 1.80m is sufficient for me to stand up comfortably. In addition, the toilet will only be used a maximum of twice a day anyway, in the morning after getting up and maybe again in the evening before going to bed.

Do I understand correctly that by individually testing whether the height above the toilet will be sufficient, it is approved by the builder or [BU] whether the toilet fits? What if the sanitation professional receives the plans and will not install it because a specialist does not do/must not do such a thing, as it would not be professional?

By the way, the toilet is probably stuck onto the shower wall in the drawing because of these heights... actually not very cozy, to say the least uncomfortable. And, I would like to point out that children often grow taller than their parents. I would really reconsider the toilet position.

Do I understand correctly that by individually testing whether the height above the toilet will be sufficient, the client or construction manager approves whether there is space for the toilet? What if the plumber receives the plans and will not install it because a professional does not do/should not do such a thing as it would not be proper work?

Why should they not do it? The workplace ordinance probably does not apply here. Moreover, in our current apartment, the corner bathtub probably should not have been placed directly against the external wall. As mentioned, we have the same roof pitch and roof structure inside with rafters, and it would be like moving the corner bathtub 60 cm higher. Would the installer also not be allowed to do that? But he did, and the building was built by a property developer.

Individual testing is probably the best option here since, after all, we live in it and it has to work for us.

I am still open to alternative suggestions that do not assume the skylight is located above the bowl.

And, I would like to point out that children often grow taller than their parents. I would seriously reconsider the toilet position.

That is my own drawing because I can make changes very quickly. But we will position it in the center. As I said: I am open to alternative suggestions; I just don’t see any other option.

If in your plan the toilet shifts further towards the top of the plan, then you quickly end up in the 150 cm height range.

The problem continues, here is the original floor plan, because it contains the height lines.:


Also, the shower only starts at the 200 cm height line.

Can’t the roof be made steeper? .. Or maybe take the space in the hallway up to the stairs.

In any case, the architect’s layout of the bathroom makes more sense. Both regarding the toilet and the bathtub. The shower remains, where the showerhead cannot be at the top of the plan, but must be on the left side of the plan on the wall.
