Four reasons why this room works
1. Mix of Old and New
The two white Barcelona chairs & coffee table against the Louis chair, console table and ornate frames
2. Combination of Textures
White leather Barcelona's, softer fabric on Louis chair and the tan hide on the chair to the left of the image
3. Use of Dark and Light
White walls and ceiling, bright and airy with the heavier tones of the gold gilt mirrors, tan hide chair and leather bound books
4. Balance of Objects in the Space
No area is cluttered but there feels like there is enough going on in this room to maintain interest.
I hope you love this room as much as I do. Tell me why if I haven't already covered it.
