Good morning OONIK, Thanks for your reply. The ID told me that the price quoted is very low, and for showcase (let pple come and see the finishing, told me need to sign to submit ...(i am not sure what he meant) and told me tiles going to increase...and told me not to tell pple the quotation as it is very low). I feel very uneasy as later I find that most of the things I dont want to do such as false ceiling (L box), Design tc console, design feature wall, built full hieigh temper glass surround it to make a study room. And I recaluate the items I dont want and it reduce by another about $9K+. He only give me 1 week to make decision.... Regards. HAPPY
