that could have been rented to commercial or office tenants. A Lever spokesperson said the design choice was an intentional architectural and public-relations feature, saying, "The fact is shops don't rent for much on Park Avenue. People buy on Fifth or Madison [Avenues]. All they do on Park is walk." A further consideration was that Lever Brothers wished for the building to be a corporate symbol for itself, rather than being shared with other tenants. In addition to its 21 usable stories and triple-height mechanical space, the building contained an employees' parking garage in the basement. The enclosed section of the ground floor was largely oriented toward public use, with space for displays, a waiting room, a display kitchen, and an auditorium. Since 2003, the building's owner Aby Rosen has used the plaza and lobby as a gallery for the Lever House Art Collection. Exhibitions have included such works as Virgin Mother by Damien Hirst, Bride Fight by E.V. Day, The Hulks by Jeff Koons, The Snow Queen by Rachel Feinstein, Robert Towne by Sarah Morris, as well as several sculptures by Keith Haring and Tom Sachs. In 2003, a portion of the ground story was converted into a restaurant with rounded walls, five dining niches, and a 22-seat private balcony. The second and largest floor contained fan, stock, mail, and stenography rooms, as well as the employees' lounge and medical suite. It contains of space.

Inside the third story were the employee kitchen, dining room, and cafeteria. By 2023, the third-story terrace was being integrated into Lever Club, a amenity area for the building's tenants. Lever Club is also planned to contain conference rooms, lounge seats, and a bar and restaurant. The offices of Unilever and its subsidiaries occupied the remaining floors, with the executive penthouse on the 21st floor. At Lever House's completion, much of Lever Brothers' staff was female, so the offices were designed as spaces that "women would enjoy working in".
