I've bought a place with a basement and a staircase that 1) lands in an awkward area (too close to the basement block wall) and, 2) is too steep and uncomfortable.
I would like to relocate it so that it lands in the center of the basement. The basement affords seven cear feet from top of slab to bottom of floor joists. I believe I calculated 94.5" from the basement slab to the top of the first floor flooring.
I'm trying to find the dimensions of the final product (how to determine same) so that I can figure out if the result will fit to one side of the existing hallway.
Essentially a stairway (simple one, like I have and intend to build) consumes a rectangular area below the floor. I am visualizing a large box within which the entire stairs would fit. But I know that teh rectangular opening at teh top floor does NOT have to be the same length as the bottom. As you descend the stairs, the required head room follows the angl of the stairs and can at some equal te botto of the loor joists.
I need to design a stair so that this point comes under the existing hall wall so I can install the stairs without disturbing this wall.
I was advised that a 9.5" tread woul be accepatable and a 6." rise is "typical." Somewhere I read that there is a rise/run ratio I should follow.
I am NOT CLEAR on the way a stairway is described. e.g. I get the height is the distance between the top surfaces of the two floors connected, but am not sure of the length measurements. (my big concern at teh moment) That is is te LENGTH measured by laying a tape along the stairs and measuring from the landing to the landing (along the diagonal they form), or from a point at teh edge of the upper landing to the front of the last step at teh bottom (horizontal measurement)?
Oh, how's this: Essentially a staircase forms a triangle with a horizontal side (A), a vertical side (b) and a diagonal side (C). I want to be able to predetermine side (A) given that (b) must equal
94.5" and the rise and run must be comfortable. I also need to determine where along (C) the verticle dimension would drop below a reasonable amount of "head room."Anyone got any great sourcces?
