Seriously you guys are quick at posting this stuff...
It's worth checking ou the Video Description as it details some other update to Blueprint:
"Blueprint: Home has new content coming it's way allowing even more options for you to create your perfect pad.
- 2 New Style Packs - Asian Fusion and Nightclub
- 2 New Environments - City of the Future and Snow Capped Mountains
- 2 New Skies -- Night Time and Chameleo
There have also been some updates to the functionality. You can now select any floor and ceiling in any room, you are no longer restricted to using the same style pack. There has also been an update to the lighting inside the apartments as well an update to collision meaning furniture can be places in all corners of the room without any issues."
Releae date wise...Hopefully should clear that up tomorrow morning for you, just waiting on a region to give final sign off.
It's certainly not a two storey structure, the outside walls are higher to help keep the look different.
If you look at the Asylum Pack outer walls they have slightly higher walls and watchtowers.
