If you are a technical person, you must have the knowledge about How Much Space Required For Staircase | Minimum Space Required for Staircase | Design of Stair
To design a dog-leg staircase, you'll need to account for several key measurements to ensure it fits comfortably in your space and functions well. Here’s a general guide to the space requirements:

Total Height (Rise): Measure the total height from the floor of the lower level to the floor of the upper level. This is essential for determining the number of steps and their height.

Step Dimensions:

Tread Depth: The horizontal part of each step should be about 9-11 inches deep.
Riser Height: The vertical part of each step should typically be about 7-8 inches high.
Run of the Stairs: This is the horizontal distance covered by the staircase. For a dog-leg staircase, this includes the distance for both the upward and downward runs.

Landing: A dog-leg staircase requires a landing between the two flights. The size of the landing should be at least as wide as the staircase and deep enough to comfortably accommodate a person standing or turning. A typical minimum landing depth is around 36-42 inches.

Total Space Needed:

Width: The staircase width should be at least 36 inches, but wider is often better for comfort.
Length: The overall length will be the sum of the horizontal run of each flight plus the width of the landing. For example, if each flight is 5 feet long and you have a landing of 3 feet, you'll need at least 13 feet of space in length.
Headroom: Ensure there's sufficient headroom throughout the staircase. A minimum headroom clearance of 6 feet 8 inches is generally recommended.

Additional Space: Depending on your design, additional space might be required for railings, handrails, and clearance around the staircase.

When planning your staircase, it’s a good idea to consult with an architect or a structural engineer to ensure that all measurements are accurate and the design complies with local building codes.
