ᐅ Constructing an S-shaped facade – Construction method

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

We have a similar situation and some current quotes for the individual trades.
A sloped site offers many possibilities, but only with the right partners and a somewhat flexible budget.

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.

how this can be solved besides using thermal breaks.

Not really (?) – I suspect Schöck holds a patent on that.

Since we want to build with a basement due to the sloped site

That sounds like a specific plot. Then please say where the development plan can be found (municipality / number / name – links are not desired).

"Isokorb" is just a brand name among others like Zewa, Tempo, Inbus.
Other manufacturers offer equivalent systems (Isopro, Isomax, Egcobox...)

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?

The 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.

Sorry, I only saw the first one. However, I followed both and find them both very well done.

Correct No. 51
