Mattiebodie, I think that's a good idea. Lots of different styles work together but I think no matter how they were arranged, those chairs and sofa might just continue to fight with one another. Too bad there isn't an office or bedroom where the sofa could work! When you're ready to look for a new sofa, please post pics of the ones you're considering. We can sure try to help by discussing style, color, just how to best place everything in the room, etc. Hopefully you could get it all figured out before you spend any money.

What a lovely room you have. My first thought is to establish where your traffic area is. Each room has a natural traffic flow and you will find it frustrating if you have to divert around furniture. Breaking the room up into zones, i.e. tv watching, play space, dining area etc will make the room feel larger and you will use the space more efficiently. When it comes to tv placement, consider where the light comes in. You will want the screen placed where the light from windows won't fall on it, or where you can close a curtain. Also, whether you want to see the tv from the kitchen, or see the view the same time as watching tv. Consider if you want the space to be a conversation area, where the tv doesn't dominate, or be a dedicated tv watching space. There is a lot to think about and decisions will be based on your family's lifestyle. As for furniture, Ikea have some great items suitable for children and toy storage that are reasonably priced. For the lounge, choose the best you can afford, for the sake of comfort. Try getting one with washable slip covers. The same goes for the rug. A good quality wool rug will last a long time, comes up well with cleaning and can even be redyed at a later stage.

Hi! I agree with anniau. Your Living & Dining have heaps of space to furnish. I've designed smaller areas than yours and it was furnished perfectly. It really comes down to the the size of the furnitures you have to be in proportion with the areas minding the general traffic within the areas. Also I would suggest that your opening to the bed hallway relocated to your kid's retreat so you have the opportunity to extend your kitchen and watch the kids while you're in the kitchen :) I would place the fridge to the opposite side as well so it can be easily accessed from your entertaining areas easily. Just my 2 cents. :) I've attached a furnishing sample I did and a marked up plan of your house.

Go with your plan to feature colour Wall A and mount mirror on Wall A and place beachy art work on Wall B. My suggestion is to maybe consider using a paint colour for the featured wall that is tonally similar to paint on Wall B and not too dark so as to give room depth but not close it in with a dark heavy contrasting shade. Offsetting the hanging of the mirror closer (to the plant) could also add interest (and work with the shorter end of the sofa). Often going with you intuition is the best advice!!!
