In the Boylston Street Elevation, the wood of the folding ribbons exposes itself along with the colums. The area of entry is inset from the street and under a low ceiling to create a cave-like experience. The stairs from the inside are exposed to allow for movement to the second floor from the exterior, or from the second floor to the street. A light well along the building next door allows views to the interior and upper levels as well as through the building to the alley. The louvers on the upper levels are angled to allow views from Copley Square to the roof, and to allow light and air to penetrate in both directions.
In the Dartmouth elevation, the entrance addresses the pedestrian scale while slots of glazing allow views in and small amounts of light. The upper floors have plenty of glazing to allow light in during the day and out in the evening.
