On the floor plan it shows the closet in room #3 as running the length of the wall and having double doors:
The way it was framed however leaves the closet smaller with only a single door and a small nook on the other side of the wall in the laundry room.

I haven't been able to find pictures on other Sienna blogs to see if other houses were built in a similar way but Jenny says she remembers seeing it in the house identical to ours that we walked through several weeks ago. I'm going to ask the project manager about it the next time I talk to him to see if there's been a change in the plans or an actual error in framing but Jenny would rather have the extra nook for shelving to store linens, towels, etc. so I guess it will be staying that way.
