Hi Padmaja, im pooja talwar, for maximum utilization of space u need to break in balconies if u have one and get french windows right till ground level. so you can have a lovely dining area there or low ground sitting area where u can get outside view and spacious look too. doors which open inwards or outwards can be split into 2 so the door flaps become smaller . use mirrors huge ones carved ones on walls to reflect a larger room. also u will have to place furniture which is smaller in size . shoe racks , and cabinets can be made tall instead of having it on ground .... place on the wall hanging shelves , tall cabinets , and storage cabinets. tv can be placed on wall done up with wooden pannel. have storage up on ceiling edges rather than any where down. hope these lil suggestions help you
