Hi guys, we are planning to do a reno on our house as it is around 100 years old and a little 'tired'. We are contemplating on whether we should knock down the back walls of the house where the kitchen/dining, walk in pantry, and laundry area is. Do up the floor, and install a sliding door at the back to allow for air flow. The house is in a conservation area. The main aim of the reno would be: * to add air flow * add a second toilet and shower indoor * refresh decking at the verendah Separately we might need to rewire to the house as wiring in the roof and subfloor isn't in the tidiest state for safety. Not having done any reno before... is it an architect, town planner, or builder we need? Any recommendations?
