New semi-detached house - smart home setup with an extra 10,000 EUR?

20k is okay. I’m paying a 10K surcharge for an apartment with 110sqm. How does that well-known saying go, “If you don’t build smart, you end up with an old building”? It all adds up, after all, automatic indirect lighting in the shower. Light coves and motion detectors planned in every room. Air conditioning preparation with KNX. Every lighting circuit goes to the distribution board. Each room has 1-2 sockets 5x1.5 etc...

20k is okay. I am at a 10K surcharge for an apartment with 110 sqm. How does the well-known saying go, whoever doesn’t build smart builds an old building? It all adds up, automatic indirect lighting in the shower. Light coves and presence detectors planned in every room. Air conditioning preparation with KNX. Every lighting circuit in the distribution board. Every room with 1-2 sockets 5x1.5 etc...

May I ask how many meters of cables and empty conduits you installed in your 110 sqm apartment?

20mm Franconian empty conduits 650m. 25mm Franconian empty conduits 60m. 400m EIB cable. 320m 5x1.5. 60m 5x2.5. 45m 7x1.5.

Good day everyone,

a short report from my side. After 2 years of reading and researching, I was able to convince my wife that we should go for smart home for the new build, otherwise we would be building a house in 2021 with technology from 1980 - it worked :)

We are building a single-family house in K and the general contractor only offered smart home components upon request. Thank God, the general contractor works with an electrician who is not contractually bound to any manufacturer, so for cost reasons (28K) we were offered a system from Busch Jäger. However, since the look/feel did not fit, we switched to KNX and selected the manufacturer Jung.
In advance, my electrician shared that so far only about 30% of all new builds are equipped with smart home because the costs initially discourage and the benefit is not seen. We had this trade has removed from the general contractor for about 10K and are now working with the electrician, who would have done the electrical work anyway.

I primarily want to control only lighting/blinds/heating/ventilation/door system/alarm system via smartphone/iPad.
Scenes etc. have deliberately been omitted for now.
For 145 sqm, the offer is 37K and includes:
Jung room controllers (number currently unknown to me)
77 sockets
10 outdoor lights
3 outdoor cameras
5 presence detectors
7 step lights
1 line to the garden for the pool
1 line in the garage for the electric car
1 empty conduit for a possible photovoltaic system
5 empty conduits for TV
5 LAN connections
1 alarm system
1 x GIRA 106 door intercom system
31 x spots

I am happy to answer any further questions.

So already a 17k surcharge for something smart.

Oh God, once again someone with an affinity for spots or were they given bad advice?

Hardly any LAN though, well okay, that might work.

Price drivers are certainly the GIRA TKS, the mentioned spots and most likely also the room controllers or JUNG devices themselves.

It can certainly all be done a lot cheaper. But of course, it depends on the overall construct.

I also miss door/window contacts, weather station, etc.
