Metamorphosis Design and Staging
Too many patterns. Patterns add interest and dimension to a room. Too many patterns can get confusing. Also, patterns that don't match the same theme (antique wall paper and plaid duvet) confuse the eye as well.
Proportion and levels: everything in this room is located extremely low. The large window makes the rooms proportions look even more lopsided.
Starkness: while very modern, this room isn't exactly inviting. The room highlights the view, which is appropriate. In most cases though, a third color to the palette, a pattern or more soft textures, would be appropriate to add a sense of balance and comfort to the room.
Busy designs: used in excess, they can overpower a room. The beautiful chandelier in this room is lost in the dark ceiling and the busy floral walls.
Ultra-minimalist. Can sometimes leave the viewed with a feeling of unease, as though the room is unfinished. For certain clients, minimalism appeals to their sense of organization and lack of clutter.
Proportion: chandelier is a bit small for the room. Also, a rug or some subtle window treatments would make this room seem a bit cozier.
Silk window treatments are heavy, they made the room feel tired like...droopy eyelids. I would have gone with a combination straight drapery and an oatmeal-colored cellular shade underneath. This would have broken up the height of the window as well as given the desired amount of shade.
Balance. This room lacks it. I would have used two couches opposite each other and perpendicular to the fireplace. If the sectional is a must-have, bring it closer to the fireplace, place two small chairs or padded stools on the third plane. Remove the white animal rug and throw over the back of the couch. Use a light brown/gray cellular shade to break up the overwhelming power of the window. A woven bamboo rug in the middle of the room would add warmth and make the room feel less massive. A tall green plant in the corner would finish the room nicely.
