Wall bench, (wall-) mounted bench, floating bench... there are probably other architectural terms, too.
I don't think they go fully around a room, but window seat or banquette could work.
You would need to submit in the Illustrated Stories category, which has its own special rules for content and also for how to publish them!
So, I guess your user name is actually pronounced 'dee-rail-it', huh?
I've seen them in adobe homes. They're called a "banco." They're fairly common adjoining a fire place. Perhaps less common lining an entire room, but I saw one in a 100+ year-old home that a friend bought.
Yes! That’s the sort of thing I was envisioning.
Cool. I don't know if it's relevant, but those homes were often built into the ground so you stepped down when you entered. The excavated soil was used to make the adobe bricks for the walls. The houses are low when viewed from the outside, with windows not far about ground level, but they're normal height from the inside. They're also very energy efficient.
Go find some pics of Frank Lloyd Wright interiors. He used that bench style over and over in his architecture. The living room in Fallingwater, for example, or any of his Urizon houses.
I think you were okay with the original phrase. I doubt many people know what a banco is. Also, to pick a nit, I assume there is a door into the room so there is a gap in the perimeter?
I'd thought of that, but had not really decided. Perhaps it is something which would best be left unexplained, if only to emphasize an air of unreality.
