This is like the more modern version of what I grew up seeing in Japanese kitchens: sliding door china cabinet. I like the wood, black, glass combo. Nice that it has "open" (behind glass) shelving AND drawers.
This is a nice-looking living room with smaller rug. Perhaps the key is to frame the rug with sofas / sofa and armchair combo / sofa and the window. And another trick is to fill up the room so the size doesn't look awkward.
