In order to ground your furniture and make this high room look cozy and inviting, look for a large area rug that should fill most of the floor space with about 1 to 1 1/2 feet of wood showing at the perimeters. Make it something lively and colorful, in tones of terracotta, green, blue, beige. An Oriental rug would look great and will warm up this room and reduce the impression of height. Put a table lamp on the white table and move the sectional a little bit away from the wall. I would not replace your new drapes, that seems really wasteful. Do get a large coffee table, a square one would probably be best. If worried about children running into it, then perhaps a large square ottoman which has long wooden legs so that it has a more airy look. If you place two chairs at the open side of the couch that should help to stop children from running into the table. Do lower the clock in the dining room and the pictures in the living room, and also the TV. Additional colorful pictures on the wall will create interest at eye level and decrease the feeling of too much height. After you buy the rug choose pillows for the couch and chairs that borrow colors from to create a harmonious whole. I see now that the chandelier in the dining room is also too high. It should be much lower over the dining table. Your drapes are beautiful!

Happy for any suggestions!

There seems to be 2 schools of thought on this dilemma. Most decorators seem to be in the camp as cawaps. Keep art at eye level. Keep the room grounded. The second camp uses the space. I am squarely in the second camp, but do think that the space can get overwhelming if there is too much going on. Keep it simple.

Stay classic with SW Alabaster. It is a lovely home with some dark pieces already and this will allow things to look classic, clean and bright and show off any artwork too! Best wishes!
