would never consider a circular stairs in any residential property...don't like the function, aesthetics or feel (especially the wobble)..much happier with a return staircase enclosed underneath and a feature window to brighten the space...much more functional to use and, with the luxury of enough space, a deep landing with room for a small table and chair or bookshelves to pause and enjoy the view and, unless it's a tiny spiral for access to a mezzanine library or similar don't see how they use that much less space when they're open on all sides but maybe there's an exception that you could share

Super helpful! Thank you very much for your feedback oklouise!

A circular staircase can look stunning in the right house.

A circular staircase or a spiral, call it what you will just needs to be designed properly.

Majority of spiral staircases I've come across are way to steep (190 rise) with the treads again way to short (250 run). Even the width has been too narrow.

Even when they meet the NCC they aren't a comfortable thing to use.

I'm presuming they were all designed to 'save space'..... they don't save much space really in my experience and a standard staircase is better for usability as well.

A half curved staircase rather than a spiral or circular, would again be stunning but needs to be designed properly and in the right setting.
