Frame the View
Openings from room to room are most graceful when they accomplish two things. An opening should share a strong relationship with other openings within the space. And the view beyond the opening should be interesting and framed well.
In this room, I added the bookshelves and also changed the opening from room to room to an arch in order to echo the shape of the bookshelves. The view of the stairs is beautifully framed and invites viewers into the next space.
