Wow! What an incredible view you have! I think you first need to frame it out. I would suggest changing out the carpet with hardwood floors with a worn or weathered look. Definitely get rid of the plastic and replace with white base moulding. Next I would paint the walls a color in the pale grey or grey/blue family. Next, I would suggest some crisp white sheers to frame each window. In the pictures, it looks like the Windows on the right are two windows wide. If so, I would also place panels in the middle of those 2 windows to continue framing the view. These are for decorative purposes only and not intended to distract from the view. It looks like there is a big space between two of the windows. I would locate a large architectural piece to place on that wall to add some interest. Remove all the small items from the window ledges. Finally, I would love a round table in that space. Good luck with your reno!

Looks like the palm tree look is working so I would blend that with some succulents maybe agave which can grow large and make great statement plants. Also stick with the stones.

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

It is a pretty 'basic' look , but unless you spend big dollars , that is going to be the base you are working from . the first 2 things I'd do , is buy a waterblaster , blast everything especially bare timber ; and secondly , do every fence in a charcoal stain . Personally , I wouldn't paint the bricks , and I'd even hold off painting the block too . That brown peak has to change , I suspect I'd go a mid-Orange , to be reasonably 'sunny' . Red or yellow too bright for the cream and the style ; blue or green too old and too cold ; grey too boring ; black or brown too dark . I the short term , I'd leave the terrace panels , but do the top rail in a bright Orange , and the base timber that can be seen , in a charcoal . The stair railings I'd do in white with the same bright Orange top rail , the actual stairs in charcoal ( you may have to add a white bit at the front of each to meet Health and Safety regulations ) . Windows etc are okay IMO , but add a detail or 2 -- 2 matching $100 letterboxes ; your street number in a nice style , painted bright orange or even apricot , made from ply , and screwed or glued so it is 30mm 'out' ( protruding ) from the downstairs wall between the 2 windows ( maybe off-centre by 30cm for impact and interest ? ) OR maybe on the front fence . Then your idea of plants in big bright pots will really add too . There you go -- $2500 and some labour and some fun and it will look quite a bit better .
