Some Apple employees reportedly hate the open office plan at the company’s brand new $5 billion headquarters.

The company has spent more than six years planning and building Apple Park to precise specifications. From a 100,000-square-foot fitness and wellness center, to meticulously designed fire exit signs, the company spared no expense in getting the details right — except, perhaps, when it comes to employee workspaces.

Prominent Apple podcaster and blogger John Gruber passed along rumors that some high-level Apple staffers are unsatisfied with the company’s open floor plan — which has many company engineers working at long tables with co-workers, instead of in cubicles or offices.

Some employees have reportedly insisted on their own space outside of the main spaceship-style building.
