Love these bookshelves from the home of designer Lela Rose, featured in InStyle March 2013.  It was smart to build them into that niche to make them flush with the wall at right.

Open-Yet-Divided Living Area

What I really love about this feature (Lines in the Sand, Architectural Digest November 2012, Photos by Pieter Estersohn, design by Olson Kundig Architects) is that it allows you to see the overall view of this amazing, open living space, and then also to see a ground level view of each of the zones.

There's the living/sitting zone with that great fireplace:

Then there's the game table/library zone:

And finally that great outdoor, beachside seating area, which can be separated from the indoor zones by glass doors:

Overall a beautiful project.  Great natural palette and good division of space that still maintains a very open feeling.  I love the use of that horizontal wood "canopy" that creates the feeling of a hallway and breaks up the vertical space.
