As part of an international effort to refresh the look and feel of its retail outlets, Apple recently shut down the Penn Square Mall Apple Store in Oklahoma City, Okla., in preparation of a "next generation" renovation.

According to city planning documents unearthed by The Oklahoman, Apple is spending more than $2.5 million on the upcoming Penn Square renovation. The storefront closed on April 18 and retail operations will continue at a temporary location until construction is complete.

While specific build details were not disclosed, the build cost suggests Apple intends to include the mammoth 37-foot TV display that sits as a centerpiece at some newer Apple Stores. Custom built, the gigantic installation is estimated to cost about $1.5 million, and was first introduced to the U.S. market when a Memphis, Tenn., Apple Store received a makeover in March.

Along with the bespoke display unit, the Penn Square location is expected to boast a new open space concept dreamed up by retail chief Angela Ahrendts and CDO Jony Ive. The design features illuminated ceilings, new wooden tables and specialized accessory display cabinetry dubbed "The Avenue," among other amenities.

The Penn Square Apple Store was the company's first brick-and-mortar shop to open in Oklahoma. A satellite location was later built in Tulsa.
