I don't LOVE the rug. but I think the green curtain, built-in shelves filled with books and the (presumably) sliding ladder are wonderful. Its missing a fire place, lots of cozy blankets and an oriental rug!
Setting up a interior home library is not too hard, you simply need just a little space where you could make simple bookshelves. What is important would be to make library interior materials accustomed to make bookshelves.
If you like the look of librarylike shelves but don't want to splurge on a custom design, use bookcases to create the appearance of floor-to-ceiling built-ins. In this living room, four tall bookcases were stacked and secured to the wall with anchors.
For "formal" living room, a dark room w color accented shelves. Imagine the dark being the red, and a special color in each of the display niches. DESIGN DISTRICT loving this coral painted bookcase against the greyish slate blue wall color
