The first elevator shaft preceded the first elevator by four years. Construction for Peter Cooper's Cooper Union Foundation building in New York began in 1853. An elevator shaft was included in the design because Cooper was confident that a safe passenger elevator would soon be invented. [12]
The off-white segmental concrete shaft is 2.5m in diameter and 20m high, with a flat face to the north to which the lift is attached by steel fly-braces. A metal column rising from the top of the concrete shaft carries the steel cloverleaf platform above. The lift shaft has a metal frame, painted yellow, with translucent glass panels.
The elevators in a skyscraper are not simply a necessary utility like running water and electricity, but are in fact closely related to the design of the whole structure. A taller building requires more elevators to service the additional floors, but the elevator shafts consume valuable floor space.
A structure of shear walls in the center of a large building—often encasing an elevator shaft or stairwell—form a shear core. In multi-storey commercial buildings, shear walls form at least one core (Figure 3). From a building services perspective, the shear core houses communal services including stairs, lifts, toilets and service risers.

The piston effect has to be considered by building designers in relation to smoke movement within an elevator shaft. [4] A moving elevator car forces the air in front of it out of the shaft and pulls air into the shaft behind it with the effect most apparent in elevator systems with a fast moving car in a single shaft. This means that in a fire ...
The building's small, obround shaped windows were a design motif of the Express Lift Company, whose lift control panels featured control buttons and floor indicators of the same shape. In January 1997, the tower fell out of use after Express was taken over by Otis (who typically used its test facilities in the United States).
