I did my whole house (minus bathroom) for about $40K.

My initial budget was $20K but then I decided to add in the floating floor ($7.5K) and aircon ($5K).

Kitchen (including glass splashback and installation) $8K and this is a very small kitchen 2.6m by 3m. And I got it at 30% off. Kitchens are a rip off IMHO. I had a cheaper quote but it was going to take much longer so I went with the more expensive option - which unfortunately wasn't the best.

Painting - did with my dad, about $1K worth of materials/paint.

Extension - turned garage into playroom - $5K including carpet and paint.

Gardening - including engaging an excavator - $1.5K

Fencing - $1.5K

Plumbing - $1K

Electrician - $2k

Laundry - $500

Miscellaneous bits and pieces (Bunnings lol) $about 3K - amazing what you need when you renovate, I didn't have ANY tools so had to buy basic things like drills, screwdriver sets, drill bits, spanners, plasterboard, etc etc.

You have a LOT of uncounted-for expenses, mine were the plumber and electrician. Make sure you get good tradespeople that have a documented history.

Oh and don't get me started on my airconditioning drama... I'm thinking of suing the manufacturer for their (lack of) after-sales service...

And I haven't done the deck yet... that's the next project...
