Building a house or buying a condominium and then building a house later?

Massa Haus is a good choice, especially for self-build houses. Here, you don’t face risks like with the very small providers who go bankrupt or only fix defects after winning a legal dispute.
However, still read the construction and service description carefully because only what is stated there counts; you cannot rely on verbal promises.
Still get offers from other large prefab house companies for comparison.
You can also negotiate a lot; the salespeople all have their leeway.
Good luck with your house construction.

But it is also not a premium provider and accordingly not famous for its goodwill...

Well, Premium ??? I have already created many reports, including from Massa Haus, the botch was always caused by the builders so far. Massa Haus builds really well like all major manufacturers. I myself built my third house with Bien-Zenker. They are good, but I would have also built with Massa Haus. Bien-Zenker could simply assemble the house 6 months faster and even finished ahead of schedule.

And the issue with goodwill is not rarely complained about by the client; they blame the house manufacturer because they used the wrong primer or laid the laminate on the still damp screed too quickly because excessive thrift prevented dry heating, etc... So no advertising for Massa Haus but I have not been able to prove any mess by them yet

And K€nny, you did well to turn to a large manufacturer, forget the very small ones if you don’t want to end up with a mess on TV
Get more offers from other large ones anyway. I am happy to answer questions about heating systems that are really economical. I am happy to share my experiences
I only do this because I am now retired. To be honest, business/revenue was more important to me before
You can almost build a house without equity without losing focus. If the final sum is right and the monthly ancillary costs are low.

One more thing about the goodwill of Massa Haus. Someone complained because the tiles fell off the wall that he had done himself and not primed.
Through the walk-in shower, water got underneath, also self-performed work and faulty sealing by the client, etc.

But still read the construction and service description carefully

Massa Haus only wanted to give us this if we signed. Since I did not want to sign without the construction service description, our paths parted after the first meeting.

Only unscrupulous sellers do that to avoid questions.
To leave was the right decision
Such behavior is certainly not desired by the management
