Room 2.3 meters, depth 4 meters, can do staircase? Seek design! Seek the design drawing of stairwell. The height of the building is 3 meters, including the floor

The depth of this staircase is not enough. 2.3 meters is not bad for personal residence. Public stairs are generally no less than 2.4 meters. The step height of stairs is generally no more than 18 cm, The height of the stairs is 3 meters, and the height of each step is 15 cm. The width of the steps is generally 25-30 cm. The width of the stair platform is generally not less than half of the bay. If the calculation is based on 15 cm step: 9 * 0.25 + 1.15 m * 2 (the minimum width of the two platforms) = 4.55 M. hope to get help
