Electrical inspection, Q2, bathroom tiles, knee wall, floor-to-ceiling windows

It will cost a bit, but probably rather in the low hundreds per window. Installation and fittings are already included in the standard, so only the larger glass or the additional sash will be charged.

The low hundreds would be doable... that’s a different figure than several thousand per window. Difficult...

We have a 1.6 m knee wall, which is very comfortable.. you can sit on beds, place cupboards and shelves (of course not the 2m ones). If you can build two stories, why don't you?

.

Well, everything is eventually limited by the budget :) If a two-story option is available for an additional 10,000 €, we would do it. Considering the years and the space, it makes sense for us. But if it costs 25,000 €, the question arises again to what extent you want and can limit yourself financially. You can't have everything...

Of course, we will ask the provider once what it would cost. But as a layman, you can use the figure for your own planning or not, but whether it is "reasonable" is always so difficult to assess...

Thanks! Hm, you can never have enough sockets. I don't know, I think you don't have to just install as many as possible... they aren't that nice to look at anyway. But I was surprised, for example, that no triple socket was planned in the children's room. I'm also completely ignorant electrically, so could I just install 4 sockets side by side where a desk is supposed to go?

What exactly does crossover and two-way switching mean, at which point do you need that?

Q3, if we are sensitive. In what way sensitive? We prefer structured wallpapers..

1. You're welcome.

2. Of course you can install 4 or even 6 sockets side by side. You just must not overload the circuit with that. Roughly speaking, no more than 2.5 kW total connected load should be on that multiple socket... (so not the electric heater, 2 computers, 1 printer and a fridge).

3. Crossover switching: Switching consumers on/off from multiple places (>2) (hallways, large rooms)

4. Two-way switching: Switching consumers on/off from two places (stairs bottom, stairs top)

5. 3 & 4 are needed in hallways, living rooms, and many more (I have installed tons of them, unfortunately in the house’s electrical package there was little to none of that included, so I laid many cables myself... (with my certified electrician))

6. For structured wallpapers Q2 is sufficient.

Addition: Make sure that 5-core cables are installed wherever necessary. This allows a) a lot of retrofitting and b) good integration of motion detectors (especially outdoors, please don't forget this, by that I mean not only the house itself but front yard, garden, carport/garage,....).

you can choose between 5 or 6 cm thickness

What kind of screed should it be? Underfloor heating? The standard requires AFAIK a minimum coverage of 45 mm over the heating pipes. That rules out 5 cm thick screed, and even 6 cm could be tight. Please have the construction description read as a whole by someone who knows about it! The screed thickness is not a feature of the equipment, but follows the circumstances within the framework of the general and recognized rules of technology.

Write down the prices during your preliminary selection and, as already mentioned, have a professional review the construction service description.

Only the preliminary selection can provide you with any rough figures.
For example, we selected stainless steel strips in the bathrooms. Without the tile selection, we were already at €700. With tiles, we ended up paying nearly €3,000 more.

Don't forget the LAN cables! Some sockets can be reordered later during the rough construction phase with the electrician. An outdoor water tap should be standard. Also outdoor sockets on the terrace. Electricity for the carport/garage and outdoor lights, don't forget the Christmas lights. ;)

You need to clarify more windows, knee walls, etc. This might change the structural integrity of the house. That was the case for us.

So underfloor heating would be included in the provider's standard...
