Closing up short staircase
Input or ideas - I have a split level home, garage is 1/2 story down from first floor (7 steps). There are two access point to garage. One is an 8 step staircase we never use. I want to close it off for a large closet. The steps and walls of the staircase are poured concrete (part of the foundation). I want to anchor 2x6s on the sides and hang joists then add decking for flooring. I'll have someone with more skill frame out the door.
In the garage I will close off the door and sheet rock it like it was never there. Because the stairs are concrete I cannot make use of the space under the new closet decking. The steps eat up the useful space.
Any dangers or input from experienced home re-modellers?
