There are three main ways people renovate. They self-manage the project, meaning they find the different trades, get them to quote, co-ordinate them so the different trades turn up when and where wanted, pay them and so on. The second way is to go the all encompassing route and have one builder do everything all in one package. The third way is to hire an architect or a building professional to manage the whole thing for you.
Each method brings with it different costs and different forms of frustration, but, in theory at least the more you do yourself, the less the cost should be. As to the quality of the renovation, that can be another question entirely. So which way do you go?
That depends on your time, your building knowledge, research, expertise and your stress levels.
If you’re like most of us and working fulltime, have the family, the pets, the garden, the meals, the house and finally yourself to worry about, then the professional licensed builder or hiring the building professional may be best. You’ll usually pay a bit more, but you’re paying for quality and peace of mind.
