Yes, provided he is registered under the GST act. I also build my own house. I have spent a lot of money to finish it. Sometimes I can't imagine that I paid twenty years for my house and now I can say that I have my own property. remember I was young and wanted to build a special place for my family. At that time I lived with my wife I a small apartment and I wanted to give her more. I found the land and used Youngman boards hire to find some builders. Now we are friends with those builders and sometimes they come to us in the holidays. One of them is even my neighbor.
