West in the Tianhe District of Guangzhou, Guangdong, China. It
is the 15th tallest building in the world. It is a part of
the Guangzhou Twin Towers.
• The building was previously known as Guangzhou West Tower
and had a related project, the proposed Guangzhou East Tower,
which, at 475 m (1,558 ft), would have been eventaller,[8] though that project has been awarded to a different
design by Kohn Pedersen Fox, the 530 m (1,740 ft) Chow Tai
Fook Centre.

The Form
• Its rounded triangular plan
responds to the need for
efficient internal space layouts
and excellent environmental
performance. The tower has a
mixture of uses includingoffice space, a luxury hotel
and a top floor observation
area.
• Each of the three façades of
the curved triangular plan arealso curved in section with a
radius of 5.1 kilometers (3.17
miles) set out asymmetrically
with the widest point at a third
of the height, tapering to its
narrowest point at the top.
• Has a radius of 71 m in plan
at the widest part and 10 m on
corners
• The plan of the building has
been designed to provide
approximately 165,000 sq m
(1,776,045 sq ft) of efficient
and flexible office floor plates.

• Office floors occupy levels 2 through 67 and a FourSeasons hotel is on levels 67 through 103.
• The office plates have good usable depths from façade
to core ranging typically from 11 –15 meters (36 –49
feet) to achieve good daylight penetration.
• Above level 66 (the highest office floor) is the five-star
Four Seasons hotel. A health club is located at level 67above which back of house and kitchen areas have
been zoned. The hotel’s main lobby is located at level
70 and is accessed via shuttle lifts serving directly from
the ground.

Cladding
• Building has smooth glass cladding with glass panels
1.5m wide and one floor high.
• With 80,000 sqm of area to be covered , glass panels of
different sizes would be difficult.
• 90 % repetition was achieved with 4 standard panel
sizes.
• A unitary system of high performance glass is used to
maintain transparency to show the structural system.

Structural system
• The building utilizes the world’s tallest constructed
diagrid structure which is clearly expressed though the
building’s façade and gives the building considerable
character.
• The diagrid members are formed from concrete filledsteel tubes which provide both good stiffness and fire
protection to the structure.
• The tubular diagrid structure “nodes-out” every 12 stories
to form 54 m (177 ft) high giant steel diamonds. At the
base of the tower the structural members are 1800 mm(70 in) in diameter and reduce in size up the building to
900 mm (35 in) at the top of the building.

• Inside the exoskeleton of diagrid system, the central core
which serves the office is made in RCC with a climbformsystem.
• The structural core takes much of the gravity load of the
building’s floors and is linked back to the diagrid
perimeter structure via floor beams to create a stiff “tube-
within-a-tube” structural system.
• The inherent stiffness in the structure minimizes steel
tonnage while providing inherent stiffness and resistance
to acceleration and sway, thereby maintaining high
comfort levels for the building’s occupants.
• This stiffness and resistance to acceleration means that
no damping of the structure is required
