"Around here" is wherever they live, and we don't know because they didn't say. For all we know they could live on a farm without a single skyscraper nearby and what they said would be perfectly true.
Regardless, the brick facades on steel skyscrapers does not make them masonry building construction like in Op's picture.
I self-host a decent bit of stuff. My setup has been to rent rack space in a datacenter to put my own storage server in, plus a second server at my house that I mirror backups between. I run my own VPN, "Cloud" storage, lemmy instance, game servers, websites, CI build systems, media streaming, etc... You can find some cheap server hardware on eBay that's only a generation or two old, which you'll need if you're running in a datacenter, but for home servers it's super easy to just set up an old desktop with a battery backup.
