Aluminum pipes on self-lubricating bearings form the structure for pivot doors. The rectangular shapes form a tapering horizontal wing panel that ends vertically at pipe stiles that double as integral door pulls. Cantilevering wing panels are fastened to either side of the central pipe structure, conforming to the angle of adjacent walls. Panels lock open during the day, which directs views into the office. Entryway doors are clad in clear anodized, expanded aluminum sheets, and the conference room door is covered in solid, brushed stainless steel sheets.
