Not because they want to convert it, but because my 84 m2 two bed semi-detached house (which feels like a luxury to have to myself) would fit into their proposed 3 bed flat 5.7 times!19 Feb 2026 14:58 +0000at://did:plc:6k2urdmfigrxvuh4mfdyp7xb/app.bsky.feed.post/3mf7u6mhqz22phttps://bsky.app/profile/jbsustbuild.bsky.social/post/3meojoivozc2pThis probably belongs here, really.
