Builders quotes are ridiculous so we are going to build the house

[zippitippitoes]

ourselves ie sub contract and project manage

has anyone else done this?

No!!

But my dad has bought a plot of woodland with an old house on it. He has permission to demolish it and re build. I presume he will manage it, and use companies that he is familiar with to do the actual buils, though I expect he will do much of the interior.
