alternate option is wooden framework with flexiply ,finished with plain veneer& paint or duco finish

hi struti I would say it's matter of choice. marble or even granite or rough stone will have its own charm and definitely long lasting but only when staircase passage is comfortable huge. if space is compact wooden stairs would be better as its could be playfull with spiral or even basics with moulds and finishes, giving staircase elevation a contemporary look thanks shradha shah beescheese design

Hello Kushboo Exterior walls can be cladded using tiles, granite or hpl panels. Use a combination of hpl panels and tiles, it would give a modern look to the elevation. Regards Srikanth Meticular Interiors
