My appraiser and I have a different opinion. Although I have only been in the new house for three weeks, I have received exactly what I ordered, planned, and paid for. And precisely because of the developer, I was spared all the hassle that this forum is full of.
I am glad to read that. And I certainly did not want to give the impression that one has to look for the good guys with a magnifying glass, or that all developers would better be sent to the devil. The business concept "developer" is indeed sensible, and that for "both sides."
However – well, forums are probably only partly representative – one also quite often reads about cases where such "packages" included a mediocre planner. The threads on the subject of wall construction (or basement construction) also not infrequently describe partners of the house builder who are not very flexible.
