White-matte cabinets (flat panel, not shaker) and white bench (or maybe epoxy sealed marine ply??...siriuskey can tell you about that), mirror splash. Love the ceilings. I personally would go for a modern, stream-line, no handles, integrated appliances look. This space has real potential to be very cool, even with the slate. It doesn't need any more more texture or darkness. This is a nice kitchen, you should be able to sell it on ebay.

I just googled & found this site, which quotes cost of R2.5 75mm. there are other suppliers as well. What was quoted to you for cost of roof installation, and was it itemised so you can see exactly what thickness the foil-backed insulation builder will use? I'm guessing the thinner (lower R factor). So, the new quote should reflect a credit for the cost of previous insulation, since it won't be used, then cost of thicker insulation added. Does that make sense? If you are unsure, best to speak with the builder. https://www.pricewiseinsulation.com.au/product/heavy-duty-fletcher-permastop/

Yes go monument!and if you go for some lime acacias out the front (tall weeping or the low bush)it would brighten up you whole look.Also adding strappy green plants that bulk up would give it a bit more of a clean look. If you don't want to go monument on roof go a light grey and tie in with a couple of tall light grey planters on either side of your door. Pleas please please!find someone with a jigsaw and cut the tops off your pickets to give a cleaner look before you paint them. I'm stating the obvious but those security screens are pretty overwhelming,can you just have them on windows that can be opened,it might not look so busy out the front.

are the new sliding glass doors double glazed? are the original windows single glazed or in need of replacing for any other reason? do you hate the beige colour? how many of the old windows can be seen at the same time as the new doors? ... inside looking out is the most important view for me but what do you like the look of?
