Hi eclipse 66 I'm sorry to hear about your break in. This is quite tricky to picture as I wasn't certain which walls related to which, but I will give this a go. I wonder if your ceilings are around the 2.4mtr mark, as your doors suggest. Although you have many windows that are probably floor to ceiling, each room is sectioned off by this central corridor, so no real natural light gets down there, is that right? The little natural light that might filter through would be absorbed by the walls, and the colour you have on these walls would not be easily seen. Without. Sounding too mainstream here, I would absolutely paint an offwhite wall the entire corridor and each adjoining living area off that, with exception to your kitchen. All ceilings purest ceiling white along with the window frames and all internal doors. The walls in a satin finish to help the light reflect a little, and move around the wall without being too shiny. You haven't mentioned your floor? Try to keep it consistent in all the living areas including your hallway, and only carpet the bedrooms as these doors would be closed often. With the door filled hallway being a white gloss finish, and a white ceiling in a flat white, the walls will feel a little warmer in comparison, although still a white, perhaps something like a hog bristle 1/4 strength by dulux. In your main living room, and kitchen, paint the hog bristle in full strength, so it feels warmer, as these spaces flow onto each other, feeling larger as a whole. With your doors being so tall, (or the ceiling being comparably low), hang your window rods if any right at ceiling level, use a sheer curtain that even when partly closed let's light filter through, they dress the window but won't block light, for that install roller blinds that will roll right up exposing as much daylight as possible, and if privacy is a factor, the sheer will provide a buffer and still seem light filled. Even if these are never used, framing the window will place an emphasis on the window frame, and more importantly the light they provide, swell as an illusion of vertical space even without it. Aother suggestion for that hall is to use this principle to heighten the ceiling, visually, is to use lining boards vertically, or a wallpaper with a strip or vertical print. Drawing you eye upward toward the end, with a wallpaper, I'm thinking of one I've seen many times over, it's a white or cream background, with an image of birch trunks, the base or top of the trees arent revealed in the picture so it doesn't make the space feel from a low or high perspective. This would provide a creative distraction to the corridor, evoke a feeling as you have walking through a beautiful place, and is graphic but still very neutral. You can even paper you doors so when they're closed, the hallway won't feel so busy. I would remove carpet in the hall if you have any, because a warm closed in space without proper airflow, or light feels stuffy, and carpet absorbs sound and lint, where floorboards or hard surface atleasts has a sound walking down it, which amplifies noise and feels bigger again by comparison. Against this neutral, cohesive space, your furniture andpersonality pieces can really stand out, particularly the red. I would also use this in the kitchen somewhere, maybe a gingham check fabric on the kitchen window or just your accessories. The less is more theory also extends to colour, particularly in smaller busy spaces, minimize these elements, like the repeat of doors and architraves on your walls, by tying them in with single colour, and keep your decorations either in a theme or single colour hue. Scatter your colour around so visually you have somewhere your eye is drawn to around the space. If you get pictures I will know if I'm way off track, but if any of them resonate with you, then great. Good luck. Ml design

A nice whitewash wall/paint treatment would brighten it up if done in a light color. Or I would paint it but not sure if all the knots will bleed through? If so then I would use an oil base Kilz to stop bleed through and paint it depending on the interior design I want for each room. I would not paint the ceiling for a more Montana look,

Why don't you live in the house for a while and get a feel for things. The curtains are bright but if they are still good quality / newish it would be a very expensive exercise to replace them (I have just spent a few thousand just on three rooms), you can always add a few red cushions or a red toned throw over your existing couch or a rug with a red tones in to it, to tone the red down, if required. Repainting the walls is cheaper than replacing curtains and a piece of art with red tones may also help. As far as furniture is concerned it would depend on what you like style wise. Why not send us a photo after you have moved in. You may find some of your concerns disappear once you are in and settled.

Hi there. Airy concrete will create more of a contrast with the floor, tie in your white cabinetry better and it will be easier to work with in an open plan. I would actually ask you to consider Cloudburst concrete, the warmer tones will tie in better with your brown floor. https://www.caesarstone.com.au/colour/4011-cloudburst-concrete
