One problem is that your curtains aren't full enough for the wide window. Houzz might have a formula but I found one here: http://www.ehow.com/way_6038775_many-should-hung-double-window_.html. Also, try this: remove the tie backs and let the curtains fall naturally. That should help a little with the fullness. Then buy pillows that bring in those colors. You can also add color to that bookcase by painting it the same color as the wall for a more built-in look. Add more collectibles or books to the shelves. Then find a large graphic poster for that long wall. Next pull the sofa and chairs closer to the fireplace so that they have at least two feet on the rug. Pull the end table closer to the furniture. Drop the picture on the right of the window down about 5". It's way too high.

Thanks for the explanation. Try a wall that is drawers up to waist high, cupboards above that. YOu can add pull-out cutting boards at waist height so that you can put things there when unpacking groceries and putting things away in the cabinets and drawers: Drawers will help but they will not increase storage space by a factor of two. You could also add drawers where the microwave is now and continue to keep the microwave on top. Here is another wall of wood cabinets: Although it will not solve your storage problem, I recommend that you pull everything out of the cabinets and drawers, one drawer or shelf at a time. Be flexible about storing things elsewhere while the children are very small. Or discarding "aspirational cooking" implements (egg slicers, orange zesters, martini shakers. lobster-shaped gelatin molds) that just haven't been used in years. Families with children tend to accumulate an enormous amount of plastic stuff. In six months or a year, they will need different plastic stuff!

Just keep the painting or mirror within the width of the headboard & pick a piece that is not very high or deep. Good suggestion with the mirror.

I would rip out and get Pax from Ikea .BTW delete your other post.
