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.

Look at Monument instead. Wallaby looks ok but I don't think it works so well with your brick.

When I read the heading and the first few sentences , I thought OMG -- orange bricks and an orange terracota roof ! But yeah , I'd call that a blonde , with regrowth on top haha ! So its reasonably pleasant , but what to do ? Dark windows would look good , BUT even then , the overall design and even the window size all screams 80's , so you'd spend $20k or whatever to do the whole place with new windows , and it'll just be modernised 80's . And to expand on that , what Julie Herbert alluded to -- the gardens and fence look 80's too . The front fence also looks oranger than the house too -- are they exactly the same as the house , or newer and/or oranger ? One possible 'tie-in' would be some long and low panels of Coloursteel where the rails are ( basically , keep the bricks on the fence , just do in-fill panels in Coloursteel , only going the same height as the pillars ) . The roof looks a charcoal , so I'd stick with that in coloursteel for the roof , IF GOING IN THAT DIRECTION . Why I say that is because I actually think the roof would look okay if you added some mid grey terracotta tiles -- go for a speckled look . Those light grey ones would look too harsh a contrast IMO , but go go mid grey and the existing charcoal would look 'interesting' IMO , it may be cheaper than a full coloursteel roof ( you'd want to check the labour cost though ) , and if say 80% of the existing tiles can be re-used , its probably better both cost but also waste wise ? And that leaves the brown -- obviously , go charcoal there too , along with more modern plants and garden design . And while some people criticise me , because I often say do a 'sunny' ( bright red , yellow or orange ) front door , not only will it look better , it changes peoples focus , so the less attractive features aren't noticed as much -- whether passer-bys love or loath the bright front door -- they'll look at it and comment , rather than noting the brown base or orangey fence bricks .
