In every multi-family house, life is closer and more "heartfelt," with more social contacts. Whether voluntarily or not...
And: Soundproofing regulations are generally more relaxed in multi-family houses than in terraced housing estates!
Furthermore, almost everywhere the question is not whether 250 m2 of land or 700 m2 of land are allowed, but rather: 100 m2 condominium or 130 m2 in the terraced house? Thanks to the lack of land and the consequently rising prices. Therefore, the idea of 750 m2 sounds boastful and is not productive. Sorry!
