How to brighten the living room in a house that is impermeable from north to south

The layout of my house is also the same, the living room is between the south bedroom and the north kitchen, and lighting is a problem. Prepare to make the south bedroom into a wooden lattice door or a wooden lattice sliding door, as a children's room, because the bedding is exquisite, can not be messed up. For my family to have an attic, in the future the child will learn to go to the attic study, and the adults will not affect him watching TV in the downstairs living room.

The developer on the north side designed the kitchen, and I was going to make an open relaxation area with a floor so that the windows would not be blocked. Well, look at the picture and speak, and I hope that the altar friends will give good advice. This is the kitchen on the north side, ready to change the leisure area, no partition, and the living room is connected to the entrance door, the right hand side is ready to make a cloakroom, the west wall of the cloakroom is a TV wall, this is the open children's room, ready to make a wooden lattice with glass door or sliding door, I didn't determine which door is good.
