Preparation of supply lines for future external roller shutters

I am in the process of finishing the house I have bought. The house does not have external blinds, but I plan to install them in 2-3 years.
What is the best way to prepare the installation for external roller shutters?

Would it be a good idea to already prepare the control buttons and then lead the power cables to the corner of the window inside the house and hide them in a box to lead them outside the house in the future?
I don't want to damage the façade now, as I don't plan to have roller shutters fitted until a couple of years from now.

It would be optimal to lay 5x1.5 from the switchboard to the box you are writing about and 5x1.5 from that box to the manual control button.
This way of wiring will allow for any type of control in the future.

I have recently been processing the subject and :
at the existing external façade, so-called adaptive roller shutters were installed, i.e. inside the light of the window, which take up about 18cm of that light, but subtracting the width of the frames, this is practically not noticeable.
During installation, holes were drilled to get as far into the building as possible with the cable from the roller shutter, omitting the drilling in the window frame, then a furrow to the switch box (at 125cm from the floor) and of course further to the power supply of the roller shutter.
You can leave the wire in the box in the corner of the window, but it would be better to plaster the pilot tube between the corner of the window and the box with the switches. You will be able to pull the wire from the roller shutter to the box and connect there.
Remember that with this wiring system you are opting for wireless control in the future. With wired control, you will need to run the wires in a star pattern and bring them to the switchboard.
