I don't know how hot it gets in Auckland in summer (I've only ever been to NZ in winter!) but if it gets hot, then go for a pale colour. Dark roofs should be kept for cold places!

The setting is quite tropical, so a darker scheme with white trims has such a tropical holiday feel. You may consider using a concrete face brick for the lower section. This will be modern, and eliminate the need for painting, while still creating contrast with the upper level. Try a colour for the main house like Resene Evolution, or Quarter Evolution, both would be perfect for your style of home. The colour scheme that we recommend for you is our Rainforest Board which includes everything you need to bring the look together! https://www.bodoboards.com.au/collections/paint-concept/products/rainforest-paint-concept We would love to see updates as you go.. its going to be great!

Without knowing any more info , I'd say its near impossible for anyone but you to know what colour/s to choose -- do you want the house to blend in but have its own style , or do you want it to stand out ? What colours are your main furniture items and even kitchen etc ? For xxample , if keeping the beige walls , how about doing the eves and gutters and garage door in a tangy ( bright , but not glaring ) orange -- this would work with the existing colours and not require a complete repaint . BUT if your kitchen was mainly various shades of , say , green and teal , and your lounge suite and duvet covers were mainly blue hues , that may 'feel' funny , clashing with the exterior ? Of course , blue and beige exterior may not work with the brown aluminium , as youve recognised . Another option ( a bit hard to tell from the pictures ) is that a light grey ( repaint the beige ) with mid-charcoal base boards may work with the brown aluminium , then a bright colour on the gutters and front and rear doors to suit -- anything from sea blue to bright yellow , orange , red , even white or off-white would probably work .

There is a lot of paste and size residue still on the walls. Washing and scraping helps but it still feels like it's there. Would a good sanding be sufficent or do I need to wash all the paste off before painting?
