We're looking into providing our son with a separate part of our house
to use as his home (he currently rents a flat locally). It all looks
fairly easily do-able but one issue is the need for a new staircase.

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
do we need to be thinking about some sort of compact/spiral one?
