ᐅ Do I need two air source heat pumps or a booster?

Hello,
I am planning to build a standard house from Weberhaus (Balance 300).
For this, I have only made slight changes to the layout by adding some extra walls, so that I end up with two separate living units.

Initially, Weberhaus said that we would need two heating systems. However, after further discussions, it turned out that we now need an air-to-air heat pump plus an additional "booster" unit, which they say would save space in the technical room compared to having two full systems (the cost is the same according to Weberhaus).

Now my question is: Is this "booster" really necessary? I did not increase the size of the house, and the standard version only has one heating system. The number of occupants does not increase just because I now have two living units.

Thank you very much for your help.
