Apple is movin' on up. In San Francisco, that is.  

The tech giant is gearing up to move its flagship retail store in the City by the Bay just a few blocks over to a larger space in the heart of the city's high-end shopping district. Apple has submitted plans to open a new store at Stockton and Post streets in Union Square to replace the existing 9-year-old store, located just three blocks away at Stockton and Ellis streets, according to a report from the San Francisco Chronicle. 

The new space, formerly occupied by Levi's, will reportedly be 45 percent larger than the existing store. A larger store will mean a bigger staff. Apple believes the new location will require 400 employees, about 50 more than the current store. 

Based on renderings posted online, the new rectangular-shaped store looks to have two levels with translucent sides and an all-glass front. No timeline for construction or opening has been announced. 

In a statement to AllThingsD, Apple confirmed it is working on the store. "We're thrilled to be working with the city of San Francisco on a new Apple retail store at Union Square," the tech giant said. "Our store on Stockton Street has welcomed over 13 million customers since it opened nine years ago, and we look forward to serving them in an amazing new location when this project is complete."

The new store is sure to stand out in the area. Apple in January trademarked the design of its retail stores, which typically include glass-panel fronts and recessed lighting.  

In 2011, Apple opened a store in New York's iconic Grand Central Terminal. Occupying 23,000 square feet, it has a staff of 350, bringing the number of Apple's New York area employees to more than 4,000.
