Hello, we have two fairly comparable offers from the above-mentioned companies, but they differ in wall construction as follows:
Heinz von Heiden:
- Porous hollow brick T12, thickness 24 cm (9.5 inches)
- Polystyrene insulation boards (fire-retardant), thickness 16 cm (6.3 inches), thermal conductivity class 035
Team Massivhaus:
- Aerated concrete blocks (H+H), thickness 17.5 cm (6.9 inches)
- Mineral wool insulation (KD), thickness 12 cm (4.7 inches), thermal conductivity class 035
- Branded facing bricks
The total wall thickness is about 45.0 cm (17.7 inches).
Which wall construction would be considered higher quality? We assume the one from Team Massivhaus due to the facing bricks.
Thanks for your thoughts on this.

Heinz von Heiden:
- Porous high-hole brick T12, thickness 24 cm (9.4 inches)
- Polystyrene insulation boards (fire resistant), thickness 16 cm (6.3 inches), thermal conductivity class 035
Team Massivhaus:
- Aerated concrete block (H+H), 17.5 cm (6.9 inches)
- Mineral fiber insulation (KD), 12 cm (4.7 inches) (thermal conductivity class 035)
- Branded facing brick
Total wall thickness is approximately 45.0 cm (17.7 inches).Honestly, neither of these wall constructions really make proper sense. If you build with external insulation composite systems (EIFS) or facing brick, the main wall can be made of a sturdy but poorly insulating material, like calcium silicate brick, instead of porous bricks or aerated concrete. These two wall setups combine the disadvantages of both approaches.

Thanks for the insights, we will take a closer look. (Creditworthiness is currently a key criterion; TMH and Heinz von Heiden have an important point here.) Please feel free to explain this in more detail: You can read financial reports (if I remember correctly, Holzmann was close to bankruptcy according to KPMG bumperlgsund, and since then I don’t trust “at least 100%” of all auditor certificates)?
By the way, there are performance bonds. Too big to fail may be nonsense, but it is still an insurable risk.

Very detailed regarding specifications/scope of work comparable. So from now on, this is exclusively about the wall construction mentioned here. I don’t quite understand: did you actively make specifications or passively compare the scope of work?

If that is your way of thinking, it makes us wonder how competent you are at evaluating things. You asked two companies about the same house (who designed it, and with what kind of exterior walls?). And now one of them is saying they would build it with a different wall structure?
Or is it more likely that you requested a “something like this” house, and the two providers responded with proposals between which you cannot see any significant differences?
In my opinion, Berlin is not a climate where a brick veneer facade would be strictly necessary. Both companies involved are well known in this forum, with Team Massiv being, in my view, a somewhat more reputable business partner than Heinz von Heiden. However, for a more narrow regional choice, an even more local supplier would generally be preferred over Team Massiv if in doubt. For example, have you also considered KB Brandis or Mein Haus (in Nauen, with whom, as far as I know, @motorradsilke and @Nida35a have built)? Yes, we have, and we were/are very satisfied. The decisive factor for us back then was that we only had 6 months. They managed it in 5 months. All trades worked perfectly together.

Of course, that doesn’t guarantee protection against insolvency, but it is a positive factor. In my opinion, a builder’s all-risk insurance is essential anyway.
