Good morning everyone,
we have decided to build a solid single-family house with Ytong. Our responsible regional Ytong partner sent us a cost estimate for our 2 designs.
We are a bit uncertain about the amount. We have not found many or any details regarding the DIN used.
Maybe someone here is familiar with it and can help us. We would like to know how the 2 prices per cubic meter he used are composed. Can I maybe save here? What would the price be for KfW 55 or completely without KfW?
We would like to be able to compare the different costs.
Thank you for your help
About the house: In general, it should be KfW 40+.
Since the building window on the plot is limited, we cannot exceed a certain size. The max is 12m wide x 15m deep. Max height is 6.75m. Maximum 2 full floors. In addition, a prescribed ridge parallel to the street.
There is also a slight slope on the plot, which we want to use to place the "basement rooms" on this side.
We sent 2 designs to the architect from Ytong.
No. 1: 2 full floors with cold roof
No. 2: 2 full floors with converted roof, knee wall 1m. For this, we get an exemption with the building application. I spoke to the responsible building authority about this.
His calculation is as follows:
2 full floors

Basement floor
11.27m x 12.92m = 145.61m² x 2.95m x 1.0 = 429.54m³
