Public Plaza

At ground floor level the public plaza which

passes beneath the tower is interrupted by

just eight steel masts that carry the entire

weight of the superstructure down to bedrock,

and transfer wind loading to the foundation.

Interior Atrium Space

the uninterrupted public passage

under the building precludes a sense

of grand processional entrance. The two

angled escalators (so positioned at thedirective

of the Chinese feng-shui, or

environmental

diviner, as are a number of other

elements in the building) that lead up

through the curved belly into the

banking

hall do provide a surrealistic effect,

but do not make up for the paucity of

the generalized plaza experience.

pushing the service cores to the perimeter so as to

create deep-plan floors around a ten-storey atrium

Vertical Movement/

Circulation

Vertical

Organization/Solid&Void

Each zone accommodates a single bank function

or several related ones, and the concept

is that the zones are social villagessubsets of the bank as a whole,

with which the employees identify.

Diagrams

In circulation, functional zones

correspond to these five structural ones

The truss levels are double height and have

specialized common functions (reception,dining..)

and the high-speed elevators, locate at the

west side of the building, are programmed

to stop at them

From these floors, vertical circulation is via

escalators, to provide a more sociable way of

moving through the zones than by elevator.

Secondary Structure

Primary Structure

Structure

At five intermediate levels,

suspension trusses suspend

the weight of the floors in the

zone below.

The structure of the building is its most

striking aspect, visually and functinally.

Both for reasons of flexible office planning and toallow clear views of the harbor from all points,

the floors are virtually column-free.

Eight mast towers, each composed of four

tubular steel columns connected by

hauched beams to act as Vierendeel

trusses, rise on either side of the building,

the front and back pairs located outside the building envelope.

The dramatization of movement continues in the double-story levels,

where switch-back escalators, along with trusses and hangers, sweep

through the space, and where glass elevator shafts and escalator

undercarriages reveal the motion of machinery.

At the central elevator core,

Foster has pulled the flooraway from the elevator shafts,

allowing a view of them rising

through the building.

There are 139 modules stacked

in towers on the east and west

sides of the building. They are

linked together by risers which

were also prefabricated in two

and three-storey high steel

frames.

ModulesSpeed, quality and compactness:

these were the three main reasons

for the decision to package the air-

handling plant and lavatories into

container-size modules.

through the glazed underbelly to the pplaza beneath the building. It has

main components: a bank of flat mirrors atta

19/21

The mirrors move in one

plane only, adjusting

to the height of the sun

above the horizon

but not to its east/west

position. This means that

the light falling inside the

building moves across the

atrium space during the day,

just as it would ifshiningdirectly through a skylight.

The mechanism is basically

the same as that for

motorized external louvers,

except that the motors are

controlled by a computer

programmed to know

precisely how high the sun

will be on every day of the

year.

Lit by the sun and cooled by seawater, it ensuresprosperity for eternity with its view of the

harbour. Indeed, its hard to imagine how thisEnglishmans building could have been any

more Chinese or more green.

one of Londons most distinctive landmarks. Butits complex facade is not just for looks, as the

diamond-shaped panels let in air for cooling andvent it as it warms up and rises.

without noting it would have been the worldslargest passively cooled building.
