Floor plan of a semi-detached house with a guest room

Building window, building line and boundary approx. 12x15m (garage must be within the building window due to regulations)

Then please treat us to the building window, drawn into the site plan.
Also the house dimensions. It may be that I overlooked the living sqm, but it would be quite interesting regarding the budget.
Hesse apparently still has "cheaper" building corners than northern Germany? That’s how I thought...
The floor plan is really not good: Too small dressing room without freedom of movement due to the sloping roof, a built-in wardrobe under the sloping roof allows more... bathroom drainage in the dining area... long corridor without a wardrobe...
And is the other semi-detached house being built by the same general contractor? Do the clients already exist?
Otherwise the suggestion to rotate the house, because semi-detached houses must of course be attached to each other, but it doesn’t have to be the long side of both.
By the way: the houses currently planned monolithically kfw40 have, from what I recall, exterior walls > 44cm thick.

Do the filled 36.5 cm stones count as monolithic construction? If yes, they should also be sufficient for Kfw 40.

I don't know. It really depends on the stone. Poroton 36.5 probably can't achieve that, I think. It was mentioned here. But I know that I have recently "accompanied" floor plans (not only here in the forum), and my pencil was shaky, the walls were that thick.

There are actually filled bricks that achieve KfW40 at 36.5cm, although I doubt that they are realistic in the price estimate. Normally, however, 42.5cm plus plaster on the inside and outside is required. Assuming 2cm each, you get 46.5cm (or 40.5cm with the very good bricks).

Here's a suggestion on the premise that the BT manages to move the technology to the upper floor. In my opinion, the room downstairs would overly enlarge the ground floor and then break the budget.




Garage and pantry are removed, as well as the 3rd room on the upper floor. Outer wall planned with 50cm.

1300€ definitely doesn’t work in Hessen. Without additional construction costs and without a basement as well as without KfW 40, which is no longer subsidized anyway (you should coordinate with the municipality whether it is still required), you can expect at least 2,200€/m2.
