Is the soffit which divides the two spaces painted a different color or is that just the lighting? The built ins are beautiful. I love the paint color! Can you tell us what your style is? Do you like straight lines? Do you like color? Of the top of my head I would say rich color rugs, curtains and lots of lamps. Those are the things I always want in my home. Not to mention art. The rest falls into place. I guess to suggest we need to know what you like and the feeling you want in the space.

Pictures?

3x6 meters is not a lot of space for what you want to do. You may be asking too much of the room. Music tends to spread out, and you need a bit of space to use it. Exercise equipment is less likely to be used if you have to wrangle it out of a corner, and then you have to have room to use it. Even small dumbbells. You might be better off keeping those under your bed in a roll-out box. (although, for me, out of sight is out of mind.) But if you really want them in the space, you might find a wall rack for them, and put it at the front of the space so you don't have to climb over the music stuff to get to it and use it. Hmm, I'm not sure I'd want small children playing in a room with expensive electronic and music equipment and dumbbells in it. Unless they are being supervised on the equipment. And with all that, two sofas might be too much. one, maybe. All that said, I'd put the music equipment at the far end of the room, with a divider of the bookcases or something. Keep the kids out, and your DH will appreciate the privacy. In the front half of the room, you really have room for only one sofa, and the tv will be small because you will be only 2 meters away from it.

It depends on how dark you want to go. I think a warm dark gray could look dramatic.

You could leave the shutters/door/ceiling white while painting out the trim
