About the original floor plan: even that is poor. No one wants to look under a staircase when entering a house – it’s simply not the best side. TM has not earned any fame with any floor plan so far.
The catalog of building proposals from Team Massiv seems to me like the result of an accumulating collection of customer houses (which I fundamentally welcome as a principle compared to simply copying the Hebel prefabricated house catalog in its entirety – but one also has to "season" them, which I unfortunately miss).
Caution when abbreviating: another regional general contractor would be Tönjes and Meichsner, with whom built her "old" house, and whom I personally find more recommendable. In this respect, we should be careful not to accidentally confuse TM and T&M. Then there would be, for example, Kagebau, who are remembered here rather inconsistently. In comments by the unfortunately now passive , there are also numerous assessments of the recommendability of various owner-managed northern German general contractors, often with an addendum like "they will go out as far as Deekelsen, maybe even to Büttenwarder, but probably no further" – although searching for these comments using the local search function is a bit tedious, it is worth looking for them, since Karsten usually also addressed how their respectability as serious horse traders should be assessed ;-)
