Build your house with the same knowledge and incite as the pros. You don't have to be a skilled trade to build or renovate your house, actually you don't even have to pick up a hammer. You will however have to be task orientate, proactive and organized.
Building your house is not rocket science, it's following a roadmap of tasks, understanding the order of the tasks, being proactive and knowing how to troubleshoot any variables that may come up.
