All the suggestions above are perfectly good. However, when you have a house that is entirely painted, the options are so endless that it's easy to get stuck. I'd advise either finding photos of comparable homes in colors that you really love, and reproducing a similar palette on your home… or upload a picture of your house to a colorizing site, and play around with various combos. Sherwin Williams has a Color Visualizer that is decent. I don't mind a white house, but feel that the black trim is a bit harsh. On the railing especially- it feels like it is outlining itself too much. Reduce the contrast between the body and the rail and it will enhance the house rather than overwhelm it. You have a lot of choices, so just experiment and go with what resonates with you.

Hi V Lyon. I'm a novice at this myself so I don't have any real comments except that what you're looking at doing seems nice. But I did want to ask is what program you used to do your proposed makeover? Was it just Photoshop? Or something else? I'm keen to try this on our 1970s house to get a feel for how it might look...

i changed my setting to OZ as i was told there are not a lot of kiwis here on the forum to give advice:) hopefully some wonderful aussies can help me:)

I suspect your best course of action would be to contact a local engineer and/or builder -- without knowing what area you are in , and local rules and regulations , any advice wouldn't be much value from us , and quite possibly won't meet compliance .
