I've copied and pasted part of your list Kellz...just amended some relevant bits
Raise the house approx. 1/2 metre so that you can actually get under it and air will circulate
Rip down all the current wall linings and put gib up.
Replace the current ceilings with gib (currently textured plasterboard)
Put in the sliding door between conservatory and master bedroom.
Change the hallway to a wardrobe for the master bedroom, and a linen closet and another cupboard
Take out the front door and make it a wall to extend the conservatory
Take out corner wardrobes in both bedrooms
Paint all the internal walls of every room and the ceilings after the gib has been done.
Rewire the house.
Move the power metre box to outside so we no longer need the meter reader to come inside the house!
Remove hotwater cylinder and install gas cylinders for hot water heating.
Put up a wall to separate the toilet from the rest of the bathroom.
Extend new bathroom into where current kitchen is and put in the new shub/shower and vanity
Replace carpet and put in new carpet in the rooms which currently have grotty polished floors.
Change existing laundry into the kitchen, including a dishwasher
Change the end of the kitchen into the laundry
Replace all the plumbing (we don't have any hot water to parts of the house at the moment because the galvanised pipes are rusting from the inside out).
Put insulation in all the walls and fix the stuff in the ceiling
If we raise the house, put in underfloor insulation
Knock down the wall between the dining room and lounge, and take out the fireplace and coal range
Put in an HRV system and heat pump
Reroof (and remove the pohutukawa which is currently growing out of the chimney)
Fix the flashing on the side of the house which has been pulled out by the telephone wire to the pole
Paint the exterior of the house
Level the back yard (currently sloping and a mess)
Put in new retaining walls
Remove existing garage and put in a weatherproof one that isn't growing trees, and put in a concrete floor and driveway
Ummmm, I don't want to think about what else

We need to get rid of all the wild ginger growing around the boundary, which is a noxious weed and slightly illegal

We're starting on the work after the wedding.
ETA: OMG it's HUGE!!!
