We used this bookshelf to plug into an existing nook in our basement wall. It was very difficult to find a tall & narrow bookshelf, but this one fit the bill. We had our contractor make some slight modifications to it in order to make it look like a built-in bookshelf. The manufacturer, W.C. Heller, was very helpful in answering questions and making a modification to the order. Overall, we are happy with our purchase.
