...it is evident that this site is an urban “zero culture” site and is essentially a devastated ecosystem with little of its original top soil, flora and fauna remaining. The design approach is to re-habilitate this with organic mass to enable ecological succession to take place and to balance the existent inorganicness of this urban site. -- The unique design feature of this scheme is in the well-planted facades and vegetated-terraces which have green areas that approximate the gross useable-areas of the rest of the building. -- The vegetation areas are designed to be continous and to ramp upwards from the ground plane to the uppermost floor in a linked landscaped ramp...

A crucial urban design issue in skyscraper design is poor spatial continuity between street-level activities with those spaces at the upper-floors of the city’s high-rise towers. This is due to the physical compartmentation of floors (inherent in the skyscraper typology)... In creating ‘vertical places’, our design brings ‘street-life’ to the building’s upper-parts through wide landscaped-ramps upwards from street-level. Ramps are lined with street-activities: (stalls, shops, cafes, performance spaces, viewing-decks etc.), up to the first 6 floors.

Ramps create a continuous spatial flow from public to less public, as a “vertical extension of the street” thereby eliminating the problematic stratification of floors inherent in all tall buildings typology. High-level bridge-linkages are added to connect to neighbouring buildings for greater urban-connectivity. ...   more »

Here's another provocative TED video. McDonough shares some of his most inspiring work, including the world's largest green roof (at the Ford plant in Dearborn, Michigan), and the sustainable cities he's designing in China. -- This blip is 20 minutes.

I highly recommend watching this 3-minute video blip of Stewart Brand's TED talk. (See also SB's 1-hr. "City Planet" talk at Google.)   ~ ronjon
