A basement staircase

This staircase was entirely too steep and landed just 27 inches from a support column. The column was just inches from the center of the landing space.
Too steep! The bottom stair tread was 10 1/4" high with the majority of the others 9 to 9 1/2" high. The top step was also 10 1/4" high with a narrow top tread and another 1/2" high transition to a tile floor. The old treads were less than 8" front to back which made climbing these stairs seem much like climbing a ladder
Straight down and into the post
Additional headroom was required to accommodate the slower rise of the new staircase. A closet floor was raised and support beams were built into the walls as opposed to set under the walls. The floors were adequately supported with a support column
A slow turn in the lower section of the stair, avoided the column and maintained the same clearance to move things up and down the stairs
The new layout provides room for more treads which makes the climb much easier. All treads are evenly spaced at 8 3/16" high. The treads are all 9" front to back and the turn feels natural. The top tread is flush with the tile floor and the bottom landing step is exactly the same height as all others
Bypassing the post
15" of headroom was gained making the headroom clearance legal and comfortable.
Finished and painted, the changes become barely noticeable
