Build a terraced end house with an additional unit (GÜ) on your own

I'm concerned about the appearance of the APs: then I would have a ceiling lamp, access point and smoke detector on the ceiling in the small hallway. Not exactly beautiful.

Then just take, for example, the Unifi In-Wall Access Point and mount it as high as possible on the wall. If the Wi-Fi quality is to be good, don’t put a cabinet in front of the access point, let alone inside a cabinet.

Definitely prepare an access point on every floor. I find it almost more important in a townhouse than in a single-family house. If your new neighbor has the brilliant idea to install a router or access point on the wall towards you, he’ll blast you with 2.4GHz so that you’ll be grateful for every access point that still transmits well on 5GHz.

We have now positioned all the APs at reasonable points in the hallways. Unifi or TP-Link then offer flat access points with wall mounting. That will fit. Thanks

We are unsure about one thing in the bathroom: the toilet and hand basin are next to each other. The plumber would make the false wall for the hand basin about 10cm deep and the one for the toilet 20cm. With the basin, this gives us more space between the washbasin and the opposite wall of the walk-in shower.

Does anyone else have this as well and can show me a picture of it?

The plumber would make the pre-wall for the hand washbasin about 10cm deep and that for the toilet 20cm. With the washbasin, this gives us more space between the washbasin and the opposite wall of the walk-in shower.

I would probably consider the idea of recessing the washbasin into the pre-wall.

I would probably consider the idea of recessing the sink into the pre-wall.

He will probably not want to do that because of soundproofing.

Because of which sound insulation - are we talking past each other? I mean recessing the washbasin as a "built-in sink" into the top of the pre-wall.

I thought you wanted to omit the pretext completely.

We want a washbasin cabinet - that cannot be realized with your idea.
