Paint the inside of your door the white trim color, it will soften the space and make it seem larger. Add 2 large art pieces on the left wall and a larger vertical mirror on the right side. Paint wall color to match whatever color is adjacent to the space. Add a patterned rug with color to the walkway.

Paint a bright light color (maybe a gray with a green undertone to coordinate with the tile) and add a floating shelf and mirror for a place to drop keys and check yourself going out..

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

Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)
