One of the good things about booking appointments well ahead of time is having enough time to prepare for it. We were told that Sara (the EB CS who will meet us for the contract signing) will book us for external color selection upon signing of the contract.
I've been researching for a simple yet nice looking color for the render and found this photo from http://forum.homeone.com.au/viewtopic.php?p=40267. This is exactly what I want. We'll definitely not do the entire house render as it is way toooo expensive - $25000!! A front house render will be good enough - plus a matching bricks that will compliment the color of the render. Finally, found what I have been looking for!
