Hello,
I just have an hour to kill ...
Hello, what experiences have you had? And what can you say about the prices, are they OK or can you get it cheaper elsewhere?
First of all, I want to assure you that the manufacturer - here Ytong - doesn’t give anything away for free. You initially buy the stones plus the service of the construction manager from them ...
The offer you posted concerns "only" the pure shell construction; after that it’s "game over" and you have to take care of the interior work yourself in EL --- with a kitchen, as a "reward" on top ... (line 2.00 m or what?) ... cool, that thing will cost at most TEUR 1.5. If I quickly calculate, the complete construction in the "turnkey" variant would cost you about TEUR 250/256. For me, the offer isn’t "the" bargain now and upon careful consideration by you - even as a layman - any further thoughts should just vanish into thin air.
If I were you, I would first roughly compile the costs of the entire construction project. Then you will surely come to the conclusion that awarding individual trades on site is cheaper; including external construction supervision.
Rhenish greetings
