I propose you a distribution that get the most out of the space. Entrance is left as free as possible, with minimalistic bright furniture space will look light and wide. Living room is visually divided into two sections, dining and living, with a tall space separating shelf. Your white leather sofas will be in balance with dark wood elements, coffee table and shelves, and a touch of vivid colors you can find in pillows and decoration. Room for your kids is modern, functional, fun and bright, in there they can be creative and enjoy in colors around them.
