: It could possibly be difficult. We were over 500 km away. General contractor: "No problem at all, we've done this many times before, you just have to pack your bags and move in." All lies. Today we are living in it, but we had massive scheduling and quality issues in the middle. Lawyer, expert visits, all very expensive. Then we withheld a few percent from the final invoice due to extra work, the general contractor sued us, negotiations between the lawyers are currently ongoing. Conclusion: Have every, really every little detail included in the contract and bring a lot of time and money. Construction companies currently have their order books completely full, they quickly botch something together for you whenever they have free appointments and that's it. Very exhausting; if you can, wait a few years until this crazy construction boom calms down again. Then the companies might have more time (and thus more willingness to be careful) for the builders.
