So in our case it also takes 'rather long'. But that's because first the construction company estimates the expected costs on the initial sketches, the architect works, the construction company determines the costs, the architect adjusts, the construction company recalculates, the architect ... - The final OK for the building application drawings is expected at the beginning to middle of next month. Well, the plot has been transferred since the end of May.
There definitely won't be any start of construction this year. If the building application even gets approved this year, the basement builder will say: 'Are you crazy? I don't build a basement in frost!'.
