Hello Ravi, We should be looking at this at the time of elevation planning. For the pyramid base of 12/2 ft it needs to 8 ft high which MAY look huge depending upon the design of the house.

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.
