Latest Answer: Hi Vinay,
As far as possible have rectangular rooms. Even an 11x15 ft ratio is good. You require less steel rods to support and strengthen it. You can have a strong staircase with two support beams. With Saadarhalli stones and 2RCC beams as support, your staircase is strong. The extra thick layers of cement are more a habit done out of fear, by the contractor.
