A pergola will obstruct light into the structure. What is the structure used for? How do you plan to use the deck for? Eating? Sitting? etc? Plan the activities and the furniture you'll need and draw up a floor plan. Floor plans are important outside & inside. The steps to the deck from the lawn are a little too abrupt. Needs a transition. Consider adding cement pavers to the grass, not as an extra patio but for a nicer transition design.

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

Third vote for getting a professional involved, but i'll still offer my layman's suggestion given that you're just soliciting general ideas at this point. If it was my space, I'd switch the bathroom and the laundry room around, keeping just one of the walls currently enclosing the toilet. Its hard to estimate precise measurements from the drawing, so it may not be feasible, but here's what i mean

I think the most impact would come from a well placed, well sized Acer. You can get them grown fairly tall already, Tamata have them and I'm sure there are other places. I'd get one that grows to no more than 3 metres (although check this against your property as scale is hard to gauge from photo), and has changing colours of leaves/bark. I'd place it towards the left of the property, looking at it. That will give some balance to the windows, provide some privacy but not obscure light. It wouldn't be a cheap option but cheaper than painting the house, and would need almost no aftercare. Then some easy care phormiums in the border underneath the windows. Both phormiums and acers come in a range of colours- limes, bronze, purples, oranges, dark reds etc, so choose what you like. The acers are soft and provide movement and variety, the phormiums sharp and provide solid consistent structure. This echoes the plants that can be seen already behind and at the side of the house and should make the hour 'sit within' its environment instead of bing perched on top of it. Also, the edge of the driveway- I would dig a border to just beyond the seam of the gate, lay down a weed mat, and put some stones in there. The garden centre has a range of them, in several colours from white through green red greys and blacks. If you chose reddish (or reddish and lime/orange) tones for your acer/phormiums, I would prob buy a large specimen plant in a pot for the top of the driveway, at the eight hand side of the garage, to link the colours. And maybe paint the front door and have some pot plants there that tone in too, especially in the area near the path that can be seen from the street. For a cleaner line I'd consider painting the lower part of the decking (the vertical frontage) to tone in with your house.
