Upstairs Floor Supporting

[The_Lazy_Slug]

Afternoon All

I have a 'L' shaped stair case running between the 2 floors of my house.
(To get the idea of the top view, imagine a square divided into 4 smaller squares. Three of these are filled with the staircase)

I would like to extend the upstairs floor over the spare area (ie the 4th small square), but do not want to build a load bearing wall below and of course, can not put any kind of beam across the stairs. (I'm not that short ) Would it be OK to use a post that goes though the ground floor to a foundation and is extended up to join the joists of my loft ???? (Positioned right in the middle of the first imaginary square) This would also replace the corner newel post.

(Obviously the upstairs joists would be extended)

Any idea of post thickness would be a great help, if the idea is even legal !!!

Can any bright spark out there think of a better solution ?


Many thanks

OK, here goes.

look at your square divided into 4 smaller squares. The bottom right square is filled with stairs. the top left square is filled with stairs running at 90 degrees to bottom right - in other words you stairs turn left.

If I read it right, the top right square is not filled with stairs - it is a quarter landing. (of course it will be round the other way if your stairs turn right)

I can't see how top left can turn immediately left again without another quarter landing - and you don't have any more squares?

If you see what I mean.
