Dear fellow contributors,
I’m sharing our first attempt at the floor plan. Unfortunately, I can’t fill out the list because copying it over on my phone doesn’t work properly, sorry.

Key data:
5 children between 0 and 11 years old
2 adults in their mid-thirties
Plot of about 900 sqm (9700 sq ft), facing north
Building window edge on the street side: 17.35 m (57 ft)
Sloped site; within the building window, the ground rises about 2 m (7 ft) over 10 m (33 ft) from front to back

We want 5 small children’s bedrooms, a slightly larger office for working from home, a master bedroom, three showers, three toilets, a bathtub, and access to the garden through the living room on the upper floor. One wall in the children’s rooms should be removable later.
The attic is walkable.

We are allowed to build 2 full stories, with a ridge height of about 12 m (39 ft) and an eave height of 11.6 m (38 ft).
We would prefer a hip roof.
The current drawing is 9.5 by 11 m (31 by 36 ft), but we would like to have around 195 to 205 sqm (2100 to 2200 sq ft) of living space later; garage or storage will be added.
The back wall of the house is embedded up to about 2 m (7 ft) into the slope.

I will try to attach a rough overview of the plot.

What do you expect? The lowest energy consumption values? Or is it enough to comply with the energy-saving regulation? I imagine many children, lots of life in the house. Often doors and windows open. Thirty-centimeter (12-inch) Ytong blocks plus lightweight plaster plus silicone-based exterior plaster, as we have, should definitely be sufficient. Or something similar. Save the 18,000 and invest it in the garden. Bricks are less important than a beautiful garden.

By the way, I think it’s great that you are going through with the project of a house for seven without it turning into a palace. The plot looks nice, too.

Now get to it. Stop worrying about every little detail. Ask what the contractor can do and what they recommend as their standard. Then it will work out, be affordable, and done properly. Karsten

I wanted to ask about the 30cm (12 inches) exterior walls as well... does that really work?

The Energy Saving Ordinance is sufficient for us! Thank you

Yes, that is possible with Ytong. But you need good-quality windows and not excessively large glazing areas; then it can meet the energy-saving regulations. Our house has exactly this wall structure, purely monolithic. Many people here build like this. It is affordable and sufficiently effective. Karsten

Yes, exactly, we have planned fairly small windows.

Is building with 30 cm (12 inch) Ytong "okay," or do you have to go with KfW55 standard using 36 cm (14 inch) blocks with an extra cost of 18,000?

Listen to 11ant. Ask what the contractor can do and recommends, what their standard practice is. Then it will work well, be cost-effective, and properly done.

As long as you compare apples to apples (I assume here: both monolithic), the installer’s experience makes a difference depending on whether they use their familiar block or a different one – but not necessarily its thickness. To meet the KfW55 standard, it may well be true that using 36.5 cm (14.4 inch) blocks is straightforward, while with 30 cm (12 inch) blocks you have to carefully observe additional conditions (such as window-to-wall ratios, etc.). What could explain the 18,000 price difference? Surely it’s not just the extra 6.5 cm (2.6 inch) of block thickness?
