Beautiful.......You need a traditional craftsman from Portugal to come over to India to help you put it together again. There must be a few traditional skilled craftsmen around. Maybe someone out there will know someone who is willing to live in India for a while.........

Hello, I jut saw your comment. thanks for the same. Appreciate your suggestion. Could you please help me to get some construction engineer who can help me to design my ground floor which is about 4 ft underground where the floor and ceiling are already there. The side walls are also there. Only thing is the partition wall to be created to make as a single bedroom house. At present on the east side there is a garage and on the north side a room with toilet. We would like to convert this as a proper single bed house. Since I have a very low budget, can you please suggest how to go about it. Thanks and look forward to your advise.

Actually this type of granite when we are using flooring light different will come and you are using ordinary cement instead of white cement so that different is more so leave as it is you can do one thing if laying person is expert ask him to do buffing it will gives shinning only not polish

The waste from sink will directly drain from the bottle trap. Bottle trap is more hygienic as it doesn't allow any gases from drain into the kitchen/bathroom. The one on the floor is to allow any water (either from overflow or from cleaning the floor) to be drained out.
