Conduit for the computer network runs through the entire building. Each office and workstation is technologically identical so that no rewiring is necessary when a move takes place. Designed to provide the feel of a gracious home Mullin Consulting offices feature classic structural materials such as brass, marble and wood. Other fine touches include quality wall coverings, rich carpeting, elegant furnishings, and paintings primarily by California artists. The entirely new fourth floor houses the firm's reception area, executive offices, financial and administrative offices and three conference rooms.
Skylights run nearly the entire length of the ceiling.
Their construction is reminiscent of the building's original skylights, the remaining two of which have been placed above a new stairwell which connects the fourth and third floors. Also connecting both floors is a tree-filled atrium, whose sides are lined with the original decorative pressed tin. Near the stairway's entrance is Engine Company No. 28's original stove, discovered in the basement when the renovation began. The new construction begins toward the rear of the first, second and third floors, marked by the exit signs located approximately 48 feet forward from the back wall.
