ᐅ Construction companies wanted in the Ingolstadt - Munich area

Hello everyone,

We are planning to build a single-family house of about 140 sqm (1507 sq ft) without a basement on a plot south of Ingolstadt. We are currently looking for suitable construction companies that build solid structures. Unfortunately, we have no experience in this area and rely on your help to separate the wheat from the chaff.

So far, we have the following companies on our short list that we might contact:

- Isar Haus from Munich
- Town & Country (partner is Feiner Hausbau GmbH)
- Wand Massivhaus
- MVS Ziegelbau
- Heinz von Heiden
- Lechner Massivhaus (the company builds with klimaPOR, not sure what to think of that)

Could you maybe tell me if these companies are recommended and whether they tend to build in a higher price range or rather offer standard options?

Do you have any tips on other companies worth recommending in the region? Thanks in advance!

About a week ago, we had an appointment in Poing at Lechner Massivhaus.
They are currently building the new show house. The interior work is underway, so we were actually able to see the shell construction. It was extremely hot that day, and inside the house it felt about 15°C (27°F) cooler. We really like the building material KlimaPor, very much! However, the thinnest version with external insulation doesn’t make sense, as it destroys KlimaPor’s vapor diffusion properties. If you use it, the exterior walls should be 36.5cm (14 inches) or even 42cm (16.5 inches) thick. We have another appointment soon to get a more detailed quote for the “offer house.” I can keep you updated.
Our contact person made a good first impression. I’ve had different experiences before... A competitor actually shot themselves in the foot. I don’t need anybody who spends 2 hours self-praising...

Technical fact: The show house is equipped with a fuel cell for heating. I will take a look at it when it’s finished. When I asked where the hydrogen would come from, they explained that natural gas is converted. So basically power-to-gas, but in reverse.

Only fools reduce sums. The fact that this applies in principle to adding a colorful mix of building materials to create a wall assembly with the sole goal of achieving a specific U-value is often overlooked by those wall assembly designers who blindly trust Excel. Building physics is not some trivial science.

I would prefer a reasonably pure material wall over a lab-made hybrid ‘patchwork sandwich’ any day.

The fact that this also applies, in a way, to adding a colorful mix of building materials into a wall assembly with the sole aim of achieving a specific U-value is often overlooked by wall assembly designers who rely too much on spreadsheets. Physics is not a particularly trivial science.

I would also prefer a reasonably uniform wall over a chimera-like sandwich from the lab.

Well, then there are two of us who can think logically. I like that already.
Besides, I would prefer to avoid the building material Styrofoam and all its derivatives.

We also visited Lechner Massivhaus. Unfortunately, we didn’t even receive a quote after our appointment. However, their base price was clearly higher than the offers from “standard” brick-and-mortar suppliers.

We are now building with KMH. The planning process was very professional, and the price was reasonable. Many acquaintances in our area are building with KMH, and so far, I haven’t heard anything negative.

P.S.: By the way, I don’t understand the concept of diffusion in walls. How is that supposed to work if the wall is coated with plaster from the outside?

With KMH, you need to be careful. They sometimes build quite well, but I have also heard of significant construction defects.
