City villa in Berlin 12621 wanted - any recommendations?

Hello everyone, after long study of many posts and various experience reports, I am somewhat confused regarding our choice of a suitable construction company.
Briefly about us... young couple in their mid-30s, no children and no desire for children – income approx. €7,000 net per month + extra bonus, tendency rising. According to the financial advisor, we can easily afford financing of 650k. A plot is also available in Berlin 12621.

Now to the question, are there any recommended construction companies in Berlin/East that build city villas with approx. 150-180 sqm with a basement and double garage? For every company that came into question, you read horror stories. So far, we have looked at: Okal Haus, Helma, Roth, Kampa, Allkauf Haus, Heinz von Heiden, Town & Country.

We would be very happy about specific recommendations.

Best regards

Now to the question, are there any recommended construction companies in Berlin/East that build city villas of about 150-180 sqm with a basement and double garage? For every company considered, you read horror stories. So far, we have looked at: Okal Haus, Helma, Roth, Kampa, Allkauf Haus, Heinz von Heiden, Town & Country. We would be very happy about concrete recommendations.

The horror stories seem to be mostly about the big names. However, I find it positive at least that you are considering both "solid" builders and "prefab" builders. In this moderated section "Experiences with construction company XYZ" you can read all kinds of concrete recommendations or non-recommendations. Berlin, as the capital, has a relatively homogeneous construction price level, where it should not matter whether the builder is located in the former Soviet sector or in the "West". Including at least Brandenburg, you should be able to gather a dozen providers here. Maybe or one of the other Berlin builders can tell who their general contractor is. I don't recall any regional "wood builders" right now. Although I prefer owner-managed construction businesses, I could at least well imagine that Town & Country or Heinz von Heiden would even have several partners to choose from in the area. Is a villa instead just your preference or has it already been positively clarified that the development plan allows it?

MeinHaus GmbH in Nauen built our house, for us everything went well and relatively stress-free and fast

Unfortunately, I cannot give my GÜ an unconditional recommendation yet (the foundation slab will be poured on Thursday). The experiences so far have been mixed . I will probably only write a detailed review at the final stage. Until then, the TE is recommended almondia, an independent builder’s consultancy, which I ultimately did not use but with whom I had a nice informal introductory conversation... https://www.hausbau-forum.de/threads/bauberatung-almondia-erfahrungen.32612/post-403402

Just look regionally, and not at those who build everywhere.

Is a plot of land already available? In Berlin, the situation is such that choosing a construction company is rather secondary. Because free plots are rare, and the rule is rather that depending on the preferred location, there are no options at all. Because the big and small companies have long since divided the market.
