ᐅ Mechanical ventilation with heat recovery—is it really necessary? Looking for advice, please.

I’ve been looking around for hours and I’m still at the beginning! But I’ll start from the beginning: We’re planning a new build, 155 sqm (1,670 sq ft), KfW 70 standard, air-to-water heat pump, and a fireplace for the cold days. Four people… (anything missing?)
So far, we always thought that a ventilation system was a MUST. We’ve requested several quotes and ventilation was always included. Our newest architect (one who finally convinced us!) suggested a controlled mechanical ventilation system with heat recovery in his calculations. However, he made it very clear that it’s NOT mandatory if you ventilate properly. Cost: €10,000 (around $11,000)! We heard that for the first time… (embarrassed)
For us, €10,000 (around $11,000) is a lot of money! We haven’t been great at ventilation so far, especially in winter. But we never had mold (probably because of the 100-year-old house).
Can anyone help or give advice on how to reach the right decision? Who assists with such questions… an energy consultant?
Are there other systems or types of ventilation that are more affordable but still make sense?
Thank you very much!
