Hi, Denze! We just published an article yesterday with many tips on rug selection and placement, including how much room you should leave between it and the wall (spoiler: 12 inches) - http://ourblog.atgstores.com/?p=9278 ... We hope you enjoy the rest of the tips and wish you luck on your decorating!

You should contact a staircase contractor to provide info and pricing for this cantilever stair design. http://www.caliperstudio.com/fabrication/project-types/stairs/stone-cantilever-stair

you can give some live colour to walls, can put beautiful wall paintings and some indoor plants give peace to house , beautiful designer lights , textured paint .... all of these will help to give attractive look to your corridor.

Somin kumar, What you can do is send the layout on this wall and we will provide you the best possible solution. Tentatively you can have a platform on the 6' wall with 21" depth do you can provide 16" deep baskets and one full height cabinet which can accommodate your microwave and other utilities. You will get around 42" of platform for hot plate, a sink etc.
