I recommend that you check with your local municipality about the parking. Ask them about the size of the truck and its weight, and whether this needs a special permit. Be aware that in Switzerland each municipality has its own rules.
Some municipalities have a system whereby you can reserve parking spaces in the public road outside your home (that would otherwise be, say, "blue zone" or "white zone" or completely open) in advance. To do this, you reserve, and then collect stands from the municipality (you are renting them, for a fee) to put up on the road the night before, with the official municipal sign: "No parking here from 06h00 until 14h00", or some similar window (allowing for traffic delays). In that way, the space is [very likely to be] clear of other cars, the next day. Afterwards, you return those stands in the afternoon or the next day. You might have to pay a deposit, which would be refundable.

As you have a Doppeleinfamilienhaus, be sure to pop round to the neighbours some days beforehand, to inform them of what's happening. This, just in case they'd prefer to move their car, or take their dog out, etc. before everything gets going, and because it's a friendly thing to do.
I recommend not allowing the truck driver drive into/onto the premises, including the grass and driveway of the Doppeleinfamilienhaus, not even to turn the truck around. Those structures are often not built to bear the weight of such a heavy vehicle. If the vehicle causes any damage, there is likely to be a dispute about whether you or they are liable, and that's really more trouble you just don't need now.
