> Genuinely curious, what do you need a 700sqm house for? Do you have a very large family, and/or hobbies that require a lot of space?

Entertaining guests, large extended family, having enough space for both a pool table and a ping-pong table indoors, nice to have dedicated study (came in handy during pandemic), bedrooms are very generous so get used for more than sleeping (e.g. MiL's b/room has all her hobbies in it, jigsaw tables, crafts, etc).

People watch TV and kids play games, and they never disturb each other.

Large space is a component of standard of living; when I talk to people who've never lived in a large space, they can't imagine how their life would be improved by a large space.

Asking people "Why do you need a large house?" is like asking people "why do you need an SUV?[1]"

[1] The SUV is, IIRC, the most popular class of car sold in many countries (excluding commercial vehicles). People like nice things. I like nice houses.

I lived on 32 sqm until very recently (I moved this Thursday) and now I have 118 sqm.

700 sqm sound like an endless dusting and cleaning chore to me, unless you can afford to have servants.

You must remember there is very cheap labor. A cleaner costs 20$ a day.
