Sliced porosity block by Steven Holl Architects
Chengdu, China
2007-2012
The 'Sliced Porosity Block' will be located just south of the intersection of
the First Ring Road and Ren Min Nan Road. Its sun sliced geometry results from
minimum daylight exposures to the surrounding urban fabric prescribed by code.
Porous and inviting from every side, five vertical entrances cut through a
layer of micro-urban shopping before leading to the elevated public 'Three
Valley' plaza. A great urban terrace on the scale of Rockefeller Center, this
multi-level plaza in the center of the complex is sculpted by stone steps,
ramps, trees, and ponds and caters to special events or to a casual afternoon
in the sun. Here the public space parallax of overlapping geometries in strict
black and white is supercharged by color that glows from the shops positioned
underneath the plaza.
The three generous ponds on the plaza are inspired by a poem by Du Fu
(713-770), in which he describes how 'Time has left stranded in Three Valleys'.
(Du Fu was one of ancient China's most important poets, who spent a part of his
life in Chengdu). These three ponds function as skylights to the six-story
shopping precinct below. Residing on voids in the facades of the sculpted
blocks three pavilions are designed by Steven Holl (history pavilion), Lebbeus
Woods (high tech pavilion), and Ai Wei Wei (Du Fu pavilion).
The 'Sliced Porosity Block' is heated and cooled geo-thermally and the large
plaza ponds harvest recycled rainwater while the natural grasses and lily pads
create a natural cooling effect. High-performance glazing, energy-efficient
equipment and the use of regional materials are just a few of the other methods
employed to reach the LEED gold rating.
