I'm pretty sure there's enough space but looking at staircases from
Screwfix and such it's very difficult to workout how much space the
actually need.

We're aiming to put it in one end of our (very large) hall, the space
we'd *like* to fit it into is about 2.2 metres by 2.5 metres and has
one outside door opening into it. *Is it practical to get a
conventional staircase into this space (with a turn if necessary) or

I fitted a straight staircase with three winders at the bottom into a
3.3 metre length of floor (the "going"), and had a fairly gentle angle
of 38 degrees. The steepest angle allowed by Building Regs is 42
degrees. You should be OK.
