Our master bedroom is long (front to back) and we don't need that much space at all, so I'm thinking about building a wall and making a separate bedroom for the baby. It would cause our master bedroom to be the size of a regular bedroom, and the nursery to be a small room accessed by a door in the new wall. Our bedroom would then not have a window but I'm fine with that-- our master bath has a small window.

Has anyone done this? I've read a lot about people doing it in NYC apartments (turning a 1 bedroom apartment into a 2 bedroom apartment without a living room, etc) and I'm really interested in building a temporary wall. Our landlord is so lax about changes that I'm sure they'd be fine with it as long as it can be taken down easily.
