Sugested solution is an open space living area whitch contains three functional units - kitchen with dining room and pantry, living room and study. Intention was to connect study with living room using part glass wall, so living room looks bigger and to give both study and living room more exclusive and modern look. Living room and kitchen are partly separated with shelf and glass wall. Living room is organized like one whole so it is not just transition room like it used to be. For the kitchen, I used your current kitchen elements and added peninsula like you asked. My proposition is that you use element under TV (180x60x110) for peninsula and just add top plate at carpenter. This solution contains small pantry in the kitchen area with one accent wall with shelf niches beside dining table. Bright colors are used, considering images you added like examples - white and light grey for the walls, with two marine blue accient walls. Sofa and armchairs are light orange leather to add some warmth and cosiness. We have false ceiling in whole area in order to add some nice ambient lighting in niches. This new interior design is made to be warm and homely, but still modern, urban, elegant and inspiring.
