Stair case area takes around 10m2 off the plinth area of a floor, on both levels, i.e ground plus 1st floor. This is quite huge and has an impact financially to the cost of construction. A 100m2 bungalow has larger rooms than a 100m2 maisonette since some of the 10m2 area in the maisonette goes into accommodating the stair case.
Therefore, stairs that don’t take up much space will in effect also reduce the cost of construction.
Large spacious stairs are luxurious and can be included in luxurious houses.
