In past I had mentioned about labor: no matter which country you are in,if it is hourly basis it will progress on snail basis. If you give on contract: it will go fastern but in both cases quality is always compromised. If it is your first construction work :you will be listenig to your engineer, not all engineering works will good: it is like mechanic.
In 2010 I met a lawyer whose house was almost finished stucturally, at hardware store. I bullshit him and he wanted me to check his house.
I pointed : In the stairs should have transparent glass so the house would have more light instead of tiny kind aakhi jhyaal. Second question: where is car garage?
Third :your toilet Should be Dry toilet concept, that is very simple thing to do is , keep the shower all the way in and the comot as you inter. His was just opposit. The toilet floor should be non slippery, just to save the medical bill and injury.
He could not see all those simple thing : because this was his first house. If you are here and wanted to build a house : you should have some one who knows how to deal with people as well where to get things. Water is another problem.
