PPOR reno north shore area

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?

 

Late bump. Still keen for a contact if any

 

Are you changing the roof or external wall ?

We are in the middle of a similar sounding property on the LNS - old property as well.

We went straight to a builder - actually we more engaged the trades directly. The carpenter became the de-facto builder.

 

Thanks Tonibell. We have since gotten a builder in to have a look. Were thinking of changing the external wall, but we were recommended not to go down that path as the work will grow quite a bit when we begin touching walls.

We are now looking at leaving the kitchen alone, and instead adding a bathroom at each of what is currently the verandah. Not sure if council will approve though as it is in a conservation area . The builder recommended that we speak to a heritage architect. Is that the right person to speak to ?

 

Late update. We decided to postpone doing a renovation.

For reference, the price quoted by the 1 builder we engaged was approx $5k/sqm for areas being renovated and $2.5k/sqm for extended areas. I estimated that the cost would end up in the 500-700k region, way too rich for me after having just paid for the house. Presume these prices are above average as well. The house is in a conservation area which plays a part.
