Hi Mr Lee, thanks you very much for the prompt reply. Your advice is invaluable. I have no clue at all before i read your advices. I was planning to move in tomorrow but since the stove has not been installed, i will change to another day. I am also wondering whether we can still do minor touch up to plaster ceiling, lightings etc after we move in. Thank in advance. Your website is the best in giving advises, please keep up the good work. Cheers.
