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!

Something like this would be great!

Hey there. Go for a cooler colour palette and draw the eye to a focal point at the end of the hallway, a console table, artwork, a mirror etc. A cooler paint colour helps the small space visually recede. In terms of the doors, going slighter darker will again make the space feel bigger. Go half a shade lighter on the low ceiling than the walls, using the same colour, rather than bright white, which will look dirty in the low light. Good luck!

The roof will be a dark grey/charcoal colour. The gutters are an off white colour, windows are white and we have cream brick all the way around. I am unsure what colour to paint it. I want to keep away from green because my house is surrounded by a sea of green. My husband thinks a light grey along with a new timber front door.
