Lighting and evergreen landscaping surround the sculpture to emphasize its form.
A sunken garden containing herbs and trees has been placed at the bottom of the light well to enhance passive cooling at street level and natural light in the basement.

Circular glass panels, additional lighting, and a concrete bench surround the garden downstairs.
The space was renovated to include five adjoining exhibition spaces, a restroom, and a storeroom with concrete floors and painted walls.

A frameless glass structure and steel trellis have been added to the basement staircase entrance, which is located at the far end of the plaza.
A pre-existing wall running alongside the entrance and perpendicular to the facade was fitted with steel screens to encourage the growth of vines.

The studio is clad in the renovated foyer with walnut paneling and terrazzo floors with bronze accents.
There is a simple oval desk of fluted stone at the center, surrounded by a semi-circle extending from the slender, rectangular foyer space.
