A sturdy set of utility, self-supporting basement stairs that turn 90° near the bottom. Constructed in lumber, these are fitted into any corner against the foundation of a house, fastened to the concrete for additional strength. The walls under the staircase (enclosing storage and such) are load-bearing. Measured to fit a basement with a depth of 7'6". #90 #basement #construction #house #lumber #staircase #stairs #stud #turn #utility
