In the cutting concept the potential of natural light is introduced into many of the galleries. This would be a nonglaring, diffused natural light, bounced off ceilings through the use of specially shaped baffles. All galleries with natural light have black-out screens, which are electrically operated and allow the light to be individually adjusted for particular works. The through-block public lobby opens a free flow of public circulation to all main areas. A direct ramp down to the cinemas prevents backup in the lobby and facilitates changing programs between day and evening.
Elevators carry the public to upper galleries, with open stairs and ramps allowing a walk down.
The staff entrance is through a reconstruction of the original 1939 MoMA entry. Stairs interconnect staff offices and allow natural light to enter from above. This would be a special hall for receptions, open to the garden in summer. The main construction would go on while the Museum remains open. For example, a horizontal gallery organization would connect to existing gallery floors.
