Your best bet is to have a residential structural engineer do a site visit and a soil test. As the home is only 10 years old, it is normal to have some settlement and additional settlement after 10 years should be minor. The fact you are concerned of future settlement should be a red flag. Additionally, you are concerned about moisture. Two red flags. It is your choice, but buyer beware. Best of luck.

Hi drmdilip -- While I waited for my trumpet vines to fill in sufficiently to provide summer shade, I sewed three matching striped shower curtains together, using the button holes on each end to tie it in place. I did this because as the vine was growing new, each thin runner would drop between the rafters rather than grow straight across. After a few years now, those thin runners have become a massed layer of thick vines, all of the new growth is straight up and by the end of summer I'll be able to easily remove my temporary support and have a roof of vines. It's not rainproof though -- for that, polycarb is practical, and I love the copper above!

I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

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.
