For your family - create an entry hall and mud room - consider a wide free standing two sided "bookcase" or other wide screen piece centered in the space, just about 9' into the room, to screen the rest of the room. On the end wall, near the kitchen, try a hall tree with a bench and hooks and use a mirror over a pretty sideboard on the front wall. Shift the dining room table closer to the entry and kitchen, making the family room larger.

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

The recommended fit around a DR table is 24" larger on all sides for the chairs. You won't have that on the 6'8" side. I'm thinking the rug is going to be too small for the room 8x10 or even 9x12 would have been a better choice.

Vinotha, iIts a personal preference. If your family is used to.a circular one go for it. I find eating on a rectangular one more comfortable gives me elbow space. IMHO , a rectangular one suits the layout but not overriding what your designer have in mind. Thanks, Nitin Cornerstone Designs, Bangalore
