Peek inside the new McAllen Public Library, built inside an abandoned Walmart. The new library opened its doors in December, and was recently selected as the winner of the International Interior Design Association’s 2012 Library Interior Design Competition, according to Dave Pinter of design blog PSFK. Pinter has the scoop:

The city inherited the former Wal-Mart after the retailer closed the store and abandoned it. The decision was made to reuse the structure and create a new main library within. Meyer, Scherer & Rockcastle, Ltd. of Minneapolis were selected to handle the interior design which the city required to be functional, flexible and affordable to construct. For a library, the existing 124,500 square foot space is huge. That’s the size of about 2 1/2 football fields making the new library the largest single-story location in the US.

The bright, airy new space seems to have drawn new patrons: registration jumped 23 percent after opening, Pinter reported. See more photos at PSFK.
