Apple received some criticism for the perceived extravagance of its new headquarters, as well as its perfectionist approach to its design and construction. The use of special wood as a construction material was reported to be the subject of a 30-page guideline.[78] The design of door handles was reported to be the subject of a one and a half year debate, involving several revisions before the Apple management gave its approval.[79] Apple's desire for custom signage put the company at odds with the Santa Clara County Fire Department, requiring several rounds of negotiations due to fears it could compromise safety in case of emergencies.[80]
