terrace landscaping exterior designing terrace tile work and planning and budgeting

HI I HAVE MY HOUSE BUILT IN A GATED SOCIETY WHERE ALL THE HOUSES ARE ON A 200SQ YARD PLOT AND SOMEWHAT SIMILAR IN DESIGN , WHAT I WANT IS TO BUILT MY TERRACE AREA AS OF NOW IT IS RAW AND HAS NO TILES ON IT OR ANYTHING . BASIC REQUIREMENT IS THAT THE DESIGN SHOULD BE VERY ASTHETIC AND VERY LOW ON MAINTENANCE , ALSO WANT A SEATING PLACE TO ENJOY THE WEATHER SOME LIGHTS TO HAVE A PARTY AT NIGHT , SOME PRIVACY FROM THE NEIGHBOURS
