Sir, Its gonna cost a bomb now. There a few space saving options like spiral stairs, ribbon stairs and ladder stairs. Another option which wouldn't save much area but still open up the space is open ledge stairs . Thanks, Amit CORNERSTONE DESIGNS Bangalore

Hi, There are a number of ways in which the area under a staircase can be utilized. In case of a cramped house or space restrictions, this space can be used for providing storage, services or even a powder room as elaborated below : In case there are no space constraints and all the other areas are taken care of, the space below the stairs can be used for add ons such as a library, study, cellar or a minibar. In case there are any dogs in the house, this area serves as a spacious and compact kennel too : Apart from this, if the space is to be treated solely considering aesthetics, it can be livened up using a bit of indoor landscaping, sculptures and water body : Hope these ideas help. Do let us know what you decided to choose. All the best! Regards, RnD Atelier Nagpur

Stone is always best option for staircase durable, Looks good, edges can be designed and polished And gives natural feel.
