I'm a sucker for the neatness of the square.

there are way too many colours going on here. Your home is a traditional style and yes the cream and green are traditional colours with the reddish brick however why did you put grey around the windows??also you have red scollops above the grey and it doesn't do the house justice. What colour was there before you painted the grey?? considering grey is a more modern colour I think you were attempting to modernise the externals. in saying that the roof would have been better to paint charcoal the cream in white and then the grey and then the driveway would be done in a grey stain. but if you leave it the way it is and cover the red scolloping above the windows the same grey and the bricks below the windows near the ground grey as well then get the drive way restained to the reddish colour of the bricks on the house and then it would blend more and look inviting.

I checked the pavers that were left over from the same batch...low and behold 2 out of the 13 pavers also had the same white streaks on them. These are unused pavers. I'm now leaning towards the manufacturing stage and the retailer I have convinced of the same. He is sending someone out on Monday to see if some sort of chemical will clean them. I fear the worse but let's see how it goes on a couple of them. I agree with you all entirely, the streaks and scratches should have been seen before laying and not used. Luck is what I need for Monday, failing that, block your ears as I ask the pool renovator to pull up the defective pavers and lay new ones.... Renovating tests your body, mind and spirit sometimes lol

If you look at your inspiration picture , the door there is a similar tone to your timber , the stone is similar , the charoal trim and windows are similar . The render is lighter than Self Destruct , and appears to have an 'effect' so it looks aged and rustic . So personally I'd go lighter , but also ask your contractor if they can do the subtle rustic effect , using two slightly different tones of render , and some water and brushes .
