Forgot to mention that the main HT room had its own set of challenges while building. Being a low lying area, the initial soil tests pointed to a masonry foundation.The excavation work started (luckily) during the monsoon and we found to our horror that the water table gets quite high.The foundation had to be redesigned to a raft foundation-RCC for all the walls and floor, with additional waterproofing provided from the outside. As you can imagine this pushed up the cost a bit, but it has been worth it. This year's rains were more than usual and no leakage or seepage is to be seen.
The floor was a cement finish since I knew that some flooring would be done later, I opted for carpet, from a local source that Santhosh suggested. There are a whole raft of options including carpet tiles which are of 20 inches square and cost about Rs 60/sft, laid. I opted for a lower cost Nepali product,pp carpeting at about 23/sft laid, also used by Santhosh. The adhesive has a horrible , toxic smell that permeates the house for a while, luckily my wife and I went off on a 2 day trip a few hours after it was laid and by the time we got back it was gone!
