ᐅ Plan the ventilation system before starting the structural shell construction

Hello!
Since I need to install ventilation systems with heat recovery for my new build (semi-detached house with 4 residential units), I am considering which option to choose and what measures I can take during the shell construction phase to ensure the system is implemented optimally and cost-effectively.
A central system seems more complex, as these units require some space and I need one system for each side of the semi-detached house. In addition, planning the rough-in installation is not straightforward. Estimated cost: 2 x 7000€.
A decentralized solution appears simpler. I plan to pre-drill a hole in a 499 x 365 x 249 mm (20 x 14 x 10 inches) aerated concrete block (Ytong) in each living room before the masons start laying the walls (according to DIN 160), to save the effort later on, which definitely won’t be easier or cheaper afterwards. This means 14 holes in total, one in each living room. Cost: 14 x 500€ = 7000€.
What do you think of my plan? Are there any important points I should keep in mind?
Thanks

Actually, it's about a semi-detached house, which you would then build using semi-detached construction methods.

Are there decentralized ventilation systems that are genuinely trouble-free (quiet), preferably ones that last a lifetime? I would recommend listening to various decentralized units in person, as there are significant differences you can’t detect on paper, for example in startup behavior.
For a limited number of rooms, I would also prefer decentralized units per room and include their operation in the rental agreement. For owner-occupied single-family homes, a centralized system is more suitable.
