Luckily, we don’t have quite as many m² as you. ;)
It should only be about 450-500m² of wall and ceiling surfaces.
Fortunately, we’re taking most of the furniture with us as well.
Only the couch, coffee table, bathroom fixtures, a few scattered cabinets, and our problem child, the kitchen extension, are missing.
The extension with a tall cabinet, a corner carousel, new countertops with finishing strips would cost us just as much as the entire kitchen including appliances has cost so far. Negotiations are still pending.
We’ve already kept an eye on the furniture over the past few weeks. I think this will still be on the agenda a few more times during the quieter period.
Honestly, I dread sorting out the cabinets/cellar.
