I would break it up into various rooms, approximately 10 feet by 15 feet each, though a longer one with a long narrow (2 feet?) water feature against the wall and seating and plants in the center part would work. Plants on the wall, making it vertically green. A path leading from room to room should jog, so you cannot see straight through. Change the theme of rooms, large fancy pottery, an outdoor dining area, sunbathing area if possible.

What can be best suited to renovate a 8 feet by 40 feet entrance and adjoining 12 feet by 20 feet patio

Well it depends on your wall color as well . since you have such concrete looking floor I would recommend you can chose any electic color like lemon , orange , yellow to give a bright look and uplift room mood or chose any pastle color of your choice for subtle feel . :)

Hello, I feel that you can design this bedroom by having 1 opaque wall at the back, and 3 transparent walls using glass & steel or glass & wooden french doors. The walls should be white, with minimal accents of blue or green, use 2 layers of curtains with sheer, and brass hanging lamps. All doors can be white PU paint. Waterproofing this bedroom will be essential, so make sure you have sealed all joints and surfaces, with a minimum of 2 feet roof overhangs. Hope this helps! G
