HOW TO DESIGN A STAIRCASE

CONSIDER YOU HAVE STAIRCASE ROOM  OF 4.5M X 2.0M AND HEIGHT OF THE ROOM IS 3.0M

SIZE OF THE ROOM = 4.5M X 2.0 M
HEIGHT = 3.0 M
ASSUMING WIDTH OF THE STAIRCASE AS 1.0M

PROVIDE TWO FLIGHT WITH MID LANDING HEIGHT OF EACH FLIGHT
                      = 3.0 / 2 = 1.5 M

ASSUME 15 CM RISERS

NO OF RISERS REQURIED IS = 150 / 15 = 10 NOS

ASSUMING 25 CM TREAD

LENGTH OF THE FLIGHT = (10-1) 25 = 225 CM

WIDTH OF LANDING  = 1.0M

SPACE LEFT FOR PASSAGE  = (4.5-1-2.25) = 1.25 M

SO PROVIDE

25CM TREAD AND 15CM RISERS WITH 1.0M WIDE MID LANDING.
