The design approach is to rehabilitate 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 (i.e. GFA @ 6,033 sq.m.) 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. The design’s planted-areas constitute 3,841 sq.m. which is @ ratio 1 : 0.5 of gross useable area to gross vegetated area. Design began with the mapping in detail of the indigenous planting within a 1 mile radius vicinity of the site to identify species to be incorporated in the design that will not compete with the indigenous species of the locality. • Place Making 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). Urban design involves ‘place making’. 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 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. • Views to the Surrounding A “views analysis” was carried out to enable upper-floor design to have views of surroundings. • “Loose-Fit” Generally, buildings have life-spans of 100-150 years and change usages over-time. The design here is ‘loose-fit’ to facilitate future reuse. Features include: • ‘Skycourts’ (i.e. convertable for future office use) • Removable partitions • Removable floors • “Mechanical-jointing” of materials (as against to chemical bonding) to facilitate future recovery. • Flexible design (e.g. initially a multi-use expo building, its future use may be offices [nett lettable area of 9,288 sq.m. @ 75% efficiency] or apartments). A set of plans to show conversion to office use has also been prepared @ 75% net to gross floor efficiency. • Vertical Landscaping Vegetation from street-level spirals upwards as a continuous ecosystem facilitating species migration, engendering a more diverse ecosystem and greater ecosystem stability and to facilitate ambient cooling of the facades. As mentioned earlier, species are selected not to compete with others within surroundings. “Vegetation percentages” represent of area’s landscape character. Factors influencing planting selection are: • Planting depths • Light Quality • Maintenance level • Access • Orientation • Wind-walls / solar-panels / special glazing
