Woodworkbykirk is right. I would go with the 11.25'' treads if you have the horizontal space, and a landing would be ideal. Australian code requires a maximum of 18 straight risers before you need a landing at least 4' in length, but I consider this extreme if you have room for an intermediate landing.
Going up, there are 9 stairs on the first flight and 10 stairs on  the second, equating to 19 stairs per floor. As the WTC was 110  stories (minus one because you do not nee â¦ d stairs to the first  floor), 109 x 19 = 2,071 Stairs.   In loving memory of the 412 emergency responders who were running  in while everyone else was running out. God Bless the USA.
