The Bricks are OK, if you like them, keep that round feature deck in the brick and render the rest, or stone clad the feature and render the rest, or cheapest of all just paint the rest in a dark warm neutral and render the round feature in a lighter but similar tone. You have the windows to consider. If you changed the colour of them you could also change the overall colour scheme from warm to cool. Although a black and white scheme is current, it looks better on timber houses and in suburban and inner city areas in my opinion. There are lots of different elements to your house which would look more integrated if you chose a warm colour scheme with a maximum of 3 colours. You can even make the bricks work if you paint upstairs a warmer colour to match them and changed the tiles and front steps to wood. Wood integrates everything in a warm colour scheme.

Go grey as advised above, don't paint window frames if they are metal but leave alone, plant sasanqua camelias along the side boundaries (they can be hedged) to screen out neighbours & add greenery plus colour, landscape the front. Don't do white stones as they look dirty after a while and are blinding in the sun. I'd get rid of the stones altogether. If you are a gardener, put in box hedging and some standard roses (yes, I know done to death but they are charming), or draw up something on paper first - play with shapes. A garden makes a house look good.

Colour is a very personal choice Jon-Candice, what one person loves another will not. Greys are very fashionable at the moment, but like everything, won't always be. Are you keeping the brown aluminium framed doors and windows? If so, I would probably go with 'warm beiges' rather than 'cool greys'. Perhaps something like Colorbond Dune on the walls, with Colorbond Jasper on the columns and garage doors. Taking a pic and doing up some colour combinations on an app is a good way of visualising your finished product and sample pots are always worth the time and money as all paints change slightly with the light and location.

I can't quite follow what you mean by 'we must keep the red roof' ? Are you not painting it , or repainting in the same colour , or would you consider a different shade ? Personally , with the White Duck , I'd go for a bolder red roof , with black or charoal gutterings , stay with the crisp white windows and veranda uprights , and the end detailing on the roof , but the window sills I'd do the same red shade as the roof , and the deck a mid grey . Oh , and also , although its cliche'd , I'd do a 1 metre tall white picket fence and double gates in the crisp white , get rid of the wire mesh haha , so everything about the house and fence looks crisp and themed , but also 'period' .
