We would not have signed without individual planning.
Why taken advantage of?
It is certainly very clearly broken down what is included and what is not.
My impression is that you bought something that is not really mature yet. The result of this would be that you have to live with things that could have been done much better without them being expensive.
An example is the long distances from the kitchen to the dining room and from the bedroom to the bathroom.
Both are fine with us. We had an additional interior wall (for approx. 750.00 euros) installed between the kitchen and the dining room. It was not included in the provider’s proposal. We might still relocate the bedroom. According to the offer, this is possible at no additional cost.
