How do you replace a spiral staircase with a straight one?

Question

The current opening at the top is 52" x 52".
The existing staircase is metal with a center post, and is installed in a corner.
It is 96" from top floor to bottom floor.

Answer 1

the reason you have a spiral staircase is probably because they didn't have room for a straight staircase. You need around 42" x 12-14 feet, depending on the total height of floor to upper floor. Plus you need a landings on top and bottom. Contact a contractor, and he can give more details, but unless you do "U" or "L" shaped stairs, you may not be able to get them in. Plus about 10 feet by 42" of upper floor will have to be ripped out and floor joists headed off and side joists doubled up. This isn't a small project. And definitely not DYI, unless you very experienced.

Is that 96" or 8' from ceiling to floor, because if it's floor to floor, then ceiling height is only 7' 2" or so.

Replacing Spiral Staircase

Answer 3

measure from the ground to the top of the floor where the stair case will go divide by 7 and this will give you the number of steps needed to reach the top the space must be at least 8'6" for the riser and 3'6" for the landing .you can cramp this in a 7'by7' opening .
OR you can violate building code narrow the stair case to 30 inches increase the rate of rise per step and shorten the stair case dramaticaly .but without seeing you particular space it is impossible to tell you .

Answer 4

It is impossible to fit a straight staircase in the same space as a spiral one. A spiral staircase is vertical while a normal staircase is horizontal.

Answer 5

Need info.
Is the staircase along a curved wall?

Are they floating steps, away from a wall?

Are they preformed steel pie shape?

Add some additional info.

Answer 6

Generally, you wouldn't be able to because the space needed is different, and the underlying supporting structure would need radical changes.
