Sounds like a lot. For us, everything was really expensive and the surveyor came, I think, 3 or 4 times... measuring the shell construction, later measuring the garage, later measuring everything for the [Register/Kataster]. And at the beginning, he also surveyed the entire plot with heights and staked it out (fun fact - the red stakes then loosely stood about 0.5m beyond the old fence at the neighbor’s).... It all followed the fee schedule and was all in about 5-6 thousand.... GD
