I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

Yes, moving the bed under the picture wall would be good, and provide space for a chair and ottoman as you mentioned. And i have actually put a new set to curtains today which is a slight brown colored one. And I was thinking about painting the walls with the picture and the one with cupboards in a dark red shade and the adjacent walls something between off white to cream color. I plan to change the floor tiling too, but not at the moment. I've been thinking of making it a wooden flooring. But not sure what color to use.

great place to put your pots and pans on hooks or little shelves for the spice collection, inset fridge so it is counter depth, a cabinet or counter with a lovely mosaic, look at these cool examples. just cool little village, my restaurant is the bldg on the end, no? my raft is on the horizon splashing your feet in the pool hang a ladle by it so guests can sing while you cook that chair is just calling you yeah, well just cause they goofed and put it in the bath. Sorry, Just did not understand the pic. You can also put ikea bars with various utensils hung from them.

I think the kitchen you posted is really cheerful, young and full of energy. Nice retro feeling. It's interesting to compare it with the one below that I just found on Houzz -- which I must admit is closer to what I would choose if I were going green and yellow. But then I'm neither young nor full of energy. I love that there are so many different ways to do things. (I have to admit that in the one below I don't think the blue/turqoise accents work too well.)
