Dear cccmmm. You speak to my dream case scenario! You got lucky because you had an good architect who did everything and obviously had the manpower on his payroll. Also, it seems that you paid the material and labor cost separately (?) Anyhow, I was in search of such a person. I can go with the more reputable one-stop shops as well but I suspect it will be quite more expensive with the cost is embedded in the per sqm price (not clear what markup is reasonable). Thanks again. ~Neal.
