Also, going by the location of the house in regards of the rest of the town (away from the sea and backed by mountains, the main road converges to it), the fact looks like way more solid construction than the other houses and how it has large spacious but mostly empty spaces...

It gives me more the impression of a Town Centre from Age of Empires than a family house. I wouldn't be surprised if the place fulfils other functions besides being a family house.
