I found a website that might be quite helpful for you http://www.colourtouch.com.au/ to visualise what colours and finishes could look like on your house. You can choose a style of house that closely matches yours then choose a number of set schemes, or start with a blank canvas and play around with any colour / finish you like.

I think the same Sian, I really love the black but worried it'll be look a bit out of place?? Inside the floors will be dark laminate, mid grey walls & white trim. Ive gone for large chrome pendant lights over the kitchen island, and glass & chrome pendants throughout the house, so no black as of yet. But Ive got lots of my b&w photography I'll hang in black frames so maybe I could introduce black with the lights?

Soo exciting getting your own designed home. By way like design and woul suggest you vent rangehood/ canopy to outside and maybe your garage not wide enough to park two cars Also white is "blinding" in heat so if garage is west facing go basalt plus white stands out so you'll need light coloured bricks so garage door don't become feature Ask brick suppliers for addresses of people who built with bricks you like or their colour consultant to come up with 2 brick choices wch would suit your colour scheme. Boral has online visualiser as do colorbond and I went to brick showroom wch stocked boral Australia and they gave me addresses and then edpoje with boral cc who fir no chatge emailed me two colour scenarios fit two types bricks liked ie 4 scenarios really helpfully

I'm with oklouise -- do both doors in timber . It won't be too much , but heres what I would do to guarantee that -- the pillar I would do in a lighter coloured stacked stone -- a schist or similar . real or manufactured , but not too 'planned' or even . That brings in the timber and stone and the natural elements , but importantly it has the 2 tones and adds interest . The rest -- It is a bit dependent on roof colour , buts here's a basic idea . Go quite light colour on the main render -- maybe a light surfmist or similar . Then what is mid-grey on the illustrations , go a mid steely blue grey ; that dark panel go a lighter charcoal , unless your roof is a lighter charcoal -- in that case , I'd go a darker charcoal for the contrast .
