Currently my mothers house is over 100 years old and Im sick of spending thousands and my time repairing and fixing it.
The block is large enough to build a second dwelling down the back. Looking for a basic 2 or 3 bedroom house (nothing fancy).
I am a carpenter by trade with building knowledge to complete 90% of it. (electricity is black magic)

However my buying power for materials is next to nothing :(

My question is am I better to get a MCmansion builder to do it and I supervise and make sure they do a proper job or do I build it myself?
If anyone has any pointers or tips for building a house or getting one built please let me know. THANKS IN ADVANCE.
