I'd be inclined to move couch & armchair along wall with large recess if they will both fit. Mount TV onto flat wall opposite. You could have a low unit to house electronics, or use the one you have. Have purpose-built storage cabinet w/shelving built into smaller recess. Some of the shelving portion could be backed w/mirror to help throw light into room. Use the shelves for books, objects of art, photos etc., and the drawers or cabinet below to store things you don't want on show all the time. I also think a large area rug will ground the family room area from dining/kitchen. A neutral one perhaps or you can inject some colour. Large art pieces on wall as mentioned. A largish plant in a raised pot would add some greenery. You may find you need a floor lamp near couch & chair. Regarding the kitchen, I think you might be able to fit a narrow timber sideboard at end of island bench so you have some additional storage there. I say timber because it would warm up the coolness of kitchen. I agree undercabinet lights good idea for additional task lighting. You could either go mirror backsplash or some gorgeous tiles. As there are a several changes you want to achieve in this space, it might help to do it in stages. Storage seems to be a priority (fam rm & kitchen) and rearrangement of furniture & TV. I would tackle this first. Additional decor ie rug, art pieces on wall(s) could be addressed next. Then splashback and some additional lighting if budget allows.

Okay, firstly, this is very difficult to do without seeing the room in person. So rather than suggesting a colour, let me tell you some theory and hopefully you can work it out. The painting looks a little yellow on my screen, I think it would look different in person. You want the image to stand out. What you're looking for is contrast between the image and your surroundings. Contrast can give seperation between elements and that's what you're after, the wall to receed behind the painting. white is not cutting it because it's competing with the image. The image has some light bright tones ie it's bright and the white wall will be bright, so a while wall and the painting will both compete for your attention. the other problem you have is all of the other elements in the room are darker and warm timber, we notice warm colours before cooler colours (ie blues) first, so it's likely all of thu sis competing against each other. So to not compete with everything else, you want something cooler but also not saturated (without a lot of colour). You want people to forget about the wall. again it's very difficult without seeing the room, so any colour I give you is not going to work. Get a few swatches from Bunnings and take them home and hold them next to the picture in the room. Narrow it down the 3 paints then get a small canvas, Bunnings is cheap, paint that with your colours and rest them on the wall with the painting. Move the canvas around the wall. Good luck. Colour is difficult but just try and get something that doesn't compete with the painting.

What about random/crazy paving the driveway to match what was on the pillars. Second choice the new light coloured pebble crete, exposed Ag as it's now called ,guess it depends on your budget., this is a very simple effect and the house would still be the star

We are in midst of finalizing a exterior wall color our internal courtyard/lightwell. any recommendations for what would work. Plan is to have a few wall climbing plants to give it a garden feel. Ideally an effect paint would be perfect.
