I really like this plan, but after tearing out the old steps, I started to reconsider the plan. With the stairs turning towards the living room like this, it might prove to be a pain sometimes when we are going in and out through the front door (and when moving furniture). Accordingly, I came up with a new option (see below). This option wraps the stairs around the landing, providing access from the front hall and the living room. By cutting off the corner of the stairs/landing, the stairs do not take up as much space as if they were square. I am considering making the stairs/landing fully rounded (i.e. quarter-circle), but that might prove difficult with the bullnose on the landing, so this is the plan for now.
Any thoughts or preferences? We are truly 50/50 on this decision. The first option looks a little better in my opinion, but the second option is simpler and more functional.
