Elle Decor did a feature on Monica Lhuillier's house a while back. It's one of those houses that you'd just said, I wish I live in that!
Here are some pictures from the feature.
When you browse through the pictures think about how neutral colors can be used so elegantly. Notice also the lack of clutters and the well-edited accessories.
Furniture manufacturers that makes this style of furniture are plentiful. From the high-end, ultra expensive range you got Baker, Hickory Chair and Christian Liagre. In the more reasonable range, but still very similiar, there's John Charles Designs (now owned by American Leather), Michael Weiss for Vanguard and Bolier.
