Two thoughts

I think a larger house like she's living in makes it a lot easier to mitigate "the bad room mate" problem mentioned in a lot of comments. They likely have some filtering and process to kick someone out if they turn out weird. And recruitment is hopefully easier if you have 4 other people looking for a 5th than posting an ad somewhere.

This does seem like a potential solution for the male loneliness epidemic. I think it would be harder to check out if you're around other people. Their house seems _very_ women-styled with cooking dance parties, twerking in the garden and the ingredients. But that's just one house, each house has their own style.

Before I met my partner I looked into communal living spaces, and if this doesn't work out I might do so again, and give it a shot. I don't think living on my own is good for me long term. I get too isolated.

Author of the post here - fwiw all the houses I've lived in have had a good gender mix, though it's true none of the men wanted to join for the hip hop dance workout. In general though the men have been the better cooks!

I wanted to note that a lot of houses I've lived in have had couples. Two of our housemates in PR were a married couple who rented out the apartment they owned to come live with us. The husband was more extroverted than the wife and loved the company - and the wife loved that we kept him entertained and she got the room to herself more often :)

All this to say I simply think it's great to live with (good) roommates, whether you're male, female, single, coupled, or anything else.
