5000 pound door

Chicago, Illinois / United States of America

A board-formed concrete wall poured just above eye level encircles the property. With the first floor set down at natural grade, the textural wall provides complete visual privacy within the garden. To offer access to the garden through this protective enclosure, a door was conceived as a pivoting section of the 16 inch thick concrete wall, making it fully integrated and concealed when closed, and reinforcing the significance of the threshold between public and private as one opens it. The execution of this detail required a counter-weighted steel frame and pivoting post that was socketed into a concrete footing and slab set below grade. Over 5000 pounds of concrete was then poured into the frame that pivots on concealed thrust and journal bearings allowing for ease of operation.
