Thanks @dreamer. Certainly a lot of work ahead but really looking forward to giving my first home a new lease on life. I'll try and keep the community up to date with progress pics

Personally , I'd swap the roof ( surfmist ) and wallboard ( tranquil retreat ) colours -- you'd then probably need to go blue for the window surround timber , or maybe a charcoal or even a bluey charcoal or steel blue .

Ironically though , if you were keeping the brick facade ( I know , its pretty naff , just running through options though ) , the surfmist roof would have made quite a pleasant upgrade , but when going essentially white , grey and blue , I'd have the grey on the roof and the white on the walls .

Hi Jared, I too like your colour choices. I’d suggest though painting a large swatch on the boards before ordering your paint colours and viewing the colours over at least a couple of days, at different times. Maybe even put some paint on each NSEW aspect. Recommending this as one of the colours we’d initially chosen was much paler irl and one threw a bit more green than blue. I love surfmist, we have it on our gutters, but just check that the sun shining on it won’t reflect directly onto traffic if the roads about you are sloping or raised.

Thanks @Jan Dobson, that's solid advice.

Going to order some test pots/a4 swatches from Dulux to trial the colour choice.

I hadn't considered reflection on traffic - definitely dont want to be blinding drivers

Thanks @User, aesthetically I love the look of darker colours for the roof but became a little concerned when I saw the Solar absorbance values of darker colours (link). Although perhaps I am overthinking it....we'll be doing anticon and batts in the roof so perhaps its not as much of a concern

The existing tiles are darker than either of your choices ( probably not quite as dark as the blue though ) , plus the existing ones look clay , which absorb heat and act like a battery ( store it up ) , so I'd suspect either choice will have a cooling effect .

@User thanks for the reply. I feel a little daft, I had initially read your comment as suggesting the blue for the roof (multitasking is not my forte). I think the grey could look really nice on the roof! Going to play it out with some swatches but think you might be onto something. In terms of thermal impact, I agree that grey or surfmist would be pretty similar

I'm interested in chatting with some people currently in the renovation market for research on a new platform that will tag roof materials and colours and show you the closest property with that product. If you are interested in looking at a prototype please email me at greg@whobuiltthat.com.au. Thanks.

We’ve (mainly) finished our new build, but think that’s a great idea, Greg. Wish I’d known about it before, would have saved so much driving about and second guessing ourselves.
