Offices, nursery, sofas.

Below are his and her offices. They share the floor lamp.

Floor lamp from Anthropologie

Drafting table from World Market

Book shelf and rug from Pottery Barn

Copenhagen chair from Restoration Hardware

Bar cart from Crate & Barrel (because every "his" office needs one)

Rug, newspaper covered phone, wallpaper, and floor lamp from Anthropologie
Side table, office chair, and butterfly chair from CB2
Parsons desk from West Elm

I also created a look for a neutral nursery, which is what I eventually plan on doing when the time comes. I want the room to be cohesive with the rest of the house rather than a clearly childish room.

Crib and bedding from Restoration Hardware
Rug from Urban Outfitters (I like that it's a little more visually interesting than the classic chevron)
Sofa from Home Decorators
Chandelier from Pottery Barn (it's pretty clear that this a girl's nursery)
Cushions from Pottery Barn (although I believe these are holiday cushions, I think it still works year round for a child's room given the woodland creatures motif)

Finally, below is just a collect of green sofas that would look great in any room!
