Keep similar style as 1st floor but have open treads for light. White and dark wood then from first to 3rd floor.

Looks like a similar layout to Taylor Street?
Possibly redo the stairs on first floor with darker wood, squared off and then carry to the attic with a new 3rd floor access.
Added this not for the stairs but concept of 3rd floor open loft feel?
