Situated opposite the Plaza Hotel on 5th Avenue, this 32-foot structural glass cube encloses a glass staircase and a cylindrical elevator leading to a 25,000 sf Apple retail store.

Loisos + Ubbelohde provided site shading analysis, advanced Radiance simulations and glazing specification to fine-tune the visual and thermal performance of the entry cube. The entry delivers visual transparency from the outside while maintaining a strong visual connection between the store and the sky from inside. By day the skylight brings natural daylight underground, while at night the lighting cube is a sign.

The glass cube entry sits on a plaza surrounded by highrises that provide critical shade for much of the year.

A glass stair spirals down to the retail floor inside the glass entry cube.

Fisheye photographs were taken on site during the design phase (left) to help us predict when the surrounding skyscrapers would overshadow the glass cube.  On the right is a photograph from inside the cube after construction was complete.

Physically accurate digital models were used to predict daylight conditions under a range of skies.  Design skies representing relatively extreme conditions helped us to bracket the range of likely luminous conditions inside the cube.

The final building blends into its surroundings, particularly when it is in shade.
