For what purpose do you want to do this?
Apart from shelling out a lot of money, having a lot of trouble getting to grips with it and having trouble getting it to work properly and comfortably, you will get bored of playing with it after a few days and it will only annoy you. The humour won't even improve knowing that you'll be able to brag to family and friends that you own an ingeligent house.
As for the rest of the automation, nothing is impossible. There are ready-made solutions on the market and there are plenty of them. More or less professional solutions.
Grenton, Sinum, Fibaro, Somfy, Supla, Zamel, Ropam, Satel, Dahua and many others.
Or based on PLCs.
Unfortunately, what you have listed is a total cost from £100k upwards.
Not only is the cost of installation high, but also the maintenance and service costs are high.
In addition to the large amount of energy consumed to power all this equipment, it is not uncommon to have to pay for the costs of maintaining an account on the servers serving these devices and the people who will serve you. The slightest malfunction and you're already out a couple of hundred bucks because you have to pay a service technician.
Unless you are knowledgeable enough to handle this yourself and then spend the time.
Besides, the choice of system is determined by what you have already done at home. There are different systems. Centralised, wired with star architecture, distributed wired with bus architecture, with transmission over power cables or wireless radio. Or mixed.
If you are at the stage of building a house, it is best to prepare a central, wired system. You just have to make a design for such a system and distribute the wires. But this makes it much easier to control such a system, remove failures and also reduces costs. The disadvantage of such a system is the later expansion. This is why such a system should be designed well in advance. However, there are also systems, e.g. Grenton, which allow for later expansion via a transmission bus or wirelessly. Of course, the power supply must be present. Personally, I recommend Grenton, as it is a fully Polish product, developing dynamically and with quite interesting possibilities.
However, I can tell you straight away that you will not be able to cover everything in one system. But maybe in time appropriate interfaces and possibilities will emerge.
On the automation side, it is also worth considering the Satel and Ropam systems, which are leaders on the Polish market in the field of security (alarms) + home automation. In particular Satel, which has really good devices, stable and working well.
On the other hand, I would advise against controlling underfloor heating with room controllers, especially the ON/OFF type, which simply worsen thermal comfort and reduce the heating efficiency.
Here on Elektroda, I have already written a lot about why such floor heating control does not work.
