I felt a L-shaped sectional sofa would meet their needs for seating, and hardwood floors was a must as they have a Yorkie Poo, Chloe, who is still in the potty training days. Leather is very durable and will hide any scratches her little nails might make on the sofa. They wanted space for a computer so I added a desk behind the sofa with my favorite Louis Ghost Chair. Whoever is at the desk, can still participate in the conversation and see their 60" TV. The sofa is at the desired distance of 8-10 feet so they won't be too far or too near the TV.
The dining room gets a little punch of drama and feminity with a gorgeous red leather wallpaper. It's faux, but very hard to tell and feels soft to the touch, much like leather. I also found a cool metal wine rack that can be mounted on the wall and display their wine collection, plus there is a sense of intimacy as the chandelier is candles (electrical, that is). Above the buffet is a framed chalkboard where they can write their menu or any fun statement for the evening.
So here it is along with some photos of what I would suggest for furniture selections and fabric/casegoods.
