With the monsoon rains I cannot imagine much will protect you from the buckets of water! I have found a solution that is a permanent structure where you can twist open and close louvers so you can allow sunshine in, but lock it to block out rain. It also seems to have incorporated gutters - I am sure something like this can be found in India (or imported from China?) http://www.louvretecusa.com/ProductRange/Opening-Roof-Systems.html

Yogender Sharma To make a grass cover, the first thing you will need to ensure if whether the structure of the half basement is capable to holding a green roof. The next would be to waterproof the top again, keeping in mind the soil and the constant contact with water. Once these things are done, you need to locate were it is you want the lawn and ensure you have access to a drainage within or at best near it the area. You will then require the services of a horticulturist to help you set up the lawn. In terms of cost, it really depends on quite a few factors Existing condition of the structure Location Quality of Horticulturist Type of Green Cover etc....

vedikaseth Bombay rains are harsh! The one thing you can do is use flexible covers that work similar to roller blinds, and are transparent which allows the light to enter. There are many companies that offer such a product. Just choose one where the installation is easy and taking down the sheets is not an issue once the rains are over. Do keep in mind however that the water will still enter the balcony, you will simply be reducing the force of rains, and will require a water outlet.

Dear Vinod, That's what happens when you give a project to a carpenter cause they view it as the single element and can't imagine where and how it is going on with the space around. "They literally don't care" except the money they save in that project. As the wardrobe is glossy and dark gray you have to make-over everything in that room to makle it look better. So better go for removing it which is more economical, and if your wardrobe is done with solid wood or timber just go for wood finish paints (veener/varnish/some other) or else go for duco paint or any other that can be applied on it. But BETTER consult a Designer or an Architect to those kind of works not carpenter or some vender. And lastly remove that funky looking overhead outcrop. Have a nice day
