I like the idea of hardwood flooring and as previously said you can add nice rugs for comfort and texture, they can be changed out at any time for a different look or fashion, I found light carpet shows all spills and marks and as also previously said here dark colours show lint, animal fur and anything lighter like fluff ...I do think hardwood floors in the long run keep you from having to re-do carpet especially as you have no idea how the renters will treat your investment. I also find myself having hardwood flooring with rugs it is all so easy to keep clean.

I agree with black bamboo and oklouise -- everything looks 60's , but in a clean , updated way , with 2 exceptions and a comment ! The two that are out of character is the roof ( but its livable ) and the portico . Even the gardens look 60's inspired , and I like the overall effect . Thge comment -- it needs more colour , a bit of wow ! So the very first thing I'd do is the front door in the brightest fire engine red gloss I can , it both references the brick but it adds the wow in a small way . It will take some of the focus off the portico , but probably not enough for my taste . So I'd probably do it in Surfmist or similar -- OR a 50's apricot with a bright orange door if you are brave ! But the upstairs still lacks something -- too mehhhh . The grey in the windows I am guessing are roller blinds ? I'd change them for a mid red or orange , but that may not work with the interior colours ? So maybe wooden venetians -- brings in the natural element and touch of class , and still works well with most interiors . Especially if going wooden , I'd do downstairs windows the same -- if going for coloured roller blinds maybe not . It will look more uniform and thought out for $10-15k ( less if you do some or all yourself ) IMO .

There are 1000s of colours available. You don’t need to limit yourself to Colorbond colours like Shale Grey and Monument. What colour would make you happy every time you arrive home and see your house? The deeper blue of your sample would look great.

Dulux terrace white has a grey undertone, so should blend in well with the slate grey roof and carport roof. I would look at painting the front door slate grey to match other trims.
