We are putting on a small family room addition (approx 18'x12'). The wall facing south is 18' and will have a bank of three large windows. The west facing wall that also faces the street has one window. We are considering removing the window on the east wall to make more room for a TV/book shelves/ etc.. but are worried about losing light. This room is open to the kitchen and dining room and the dining room has three windows & glass door facing east so i think there will still be plenty of light coming in. If we keep the window it doesn't leave a lot of space for the TV (about 4').
