We are in the brainstorming phase for our own home. We plan to build a two-story single-family house with a flat roof. (Floor plans to follow.) Because of the sloping site, we want to include a basement, and since the facade facing the street will be quite massive in parts, we want to avoid the house looking like a cube. Therefore, we are considering breaking up the facade with an S-shape design.
This raises the question of how to construct the overhangs of about 0.5 m (20 inches). The cladding is intended to be done using rhombus battens.
Preferred construction method: aerated concrete blocks.
I have read about Isokörbe (thermal breaks) several times, but they are quite expensive.
If my explanation is not clear enough, I have attached some pictures.
Best regards

Take a look here: https://www.hausbau-forum.de/threads/werkplanung-efh-180qm-flachdach-mit-keller-doppelgarage.26277/ and https://www.hausbau-forum.de/threads/generelle-kritik-zu-architektur-raumaufteilung-aussenoptik.29500/ – the style goes in a similar direction.
Not really (?) – I suspect Schöck holds a patent on that.
That sounds like a specific plot. Then please say where the development plan can be found (municipality / number / name – links are not desired).

how this can be solved besides using thermal breaks.

Other manufacturers offer equivalent systems (Isopro, Isomax, Egcobox...)

So my question is, how are overhangs of about 0.5 m (20 inches) constructed? Basically, you have two options: encase the cantilever or use thermal breaks.
A few years ago, I looked into this both professionally and personally. In terms of cost, there wasn’t much difference (back then about 5%).

I have read about very high prices per meter. What are the current prices like?

benediktr14 Feb 2019 20:19The house is planned to have approximately 175 m2 (1,884 sq ft) and a projection in the living area of about 5 m by 1.5 m (16 ft by 5 ft). The site is not on a steep slope. The plot slopes from west to east by about 3 m over approximately 25 m (10 ft over 82 ft), and from north to south by about 2 m over 27 m (7 ft over 89 ft). There is already a retaining wall facing south towards the neighbor.
The house is intended to be oriented towards the southwest. The small L-shaped section will also open up in this direction. (To the west, there is forest and meadow.) Currently, I do not have a surveyed plan. However, the land is privately owned and fully serviced. For now, I can only provide a screenshot from the BayernAtlas.
Regarding the development plan: The location is a small town with about 5,000 inhabitants. §34 of the Federal Building Code (Baugesetzbuch) applies. In this district, there are a variety of houses, ranging from gable roofs and shed roofs to log cabins. Therefore, I have no concerns that the intended building style will not fit in.
@11ant: I have been following the thread mentioned above for a long time and also find the outcome very good.
Now about the budget:
As mentioned, the plot is fully serviced (gas, water, sewage). It is privately owned. We have set a budget limit of 450,000. Plumbing, heating, and ventilation (HVAC) work will be done entirely by ourselves.
So, go ahead and criticize my budget :-) I see it as realistic but tight. For your information: Last year, I already completed a house build (for my brother) with an architect and self-managed contracting.
