1500 for all cover area, what it includes.
Brick Works,
Plaster Works
Installation of Door & Windows
Boundary Wall
Boundary Wall on Roof
Sheds on windows and etc
Coz normally contractor do not take same rate for boundary wall external, main gate, doors, windows and sheds as it costs different.
I believe you are saying 1500 overall, have you include electrical, plumbing, sanitary works in it, kitchen fittings, means a complete house under 1500 or only gray structure.
