I bought a house last year and is now rented out. I'm planning to move in sometime next year so I'm putting coins to my piggy bank each day now.
I'm wondering how much will it cost to do a renovation. If it too much, I might need to double my effort to put more coins or I might just abandon the project.
My place is in Melbourne, a double stories - 4 bedrooms (3 bed in level 1, 1 master in level 2), 2 bathroom (one in each level) and double garage. As this place was last renovated since late 70s, I'm planning to tear down top floor, redesign and expand from the current size to accommodate 1 master bedroom, home office, walk-in bathroom, waiting room and a store room. I also need to change the spiral staircase to normal U-shape staircase. On the first level, I will do some renovation too but no extension.
I have no idea how to estimate the renovation cost and not sure what the budget I need to set aside. Can anyone help me how to estimate cost based on the above?
To save cost, is it possible some of the renovation to be carried out by myself or is it better to leave it all to builder?
Do I still need to submit any application to the council?
