Here's progress on the Rookery interior. This is part of the three-panel drawing of the Rookery for a private client. The center panel is the elevation drawing (finished) and this one, which will be the left side panel, focuses on all the interior details. The right side panel will focus on the exterior details. Both of the side panels are divided into smaller panels in a structure that is designed to mimic the structure of the atrium roof.
This particular interior panel is meant to exhibit the differences between the original and update interior. The Root original was heavy on iron, marked in particular by that huge iron newel/light fixture at the base of the main staircase. The original elevators had enormous, ornate grates with heavy detailing. There were none of the pendant light fixtures you see now; it depended hugely on natural light.
Frank Lloyd Wright's updates lightened up the interior with white marble surfaces and intricate gold leaf patterns that reflect the light. He brought the pendant lights consistent with his style, and placed two urn-topped newels as exclamation points to the staircase.
This project continues to give me a huge appreciation for the detailing and craftsmanship behind buildings like this. In this one, you've got a huge variety of styles, the strong tall pride of post-fire Chicago, the mark of local architectural genius in Burnham, Root and Wright, and a clever nod to city corruption in the very name of the building.
