‘Superdensity’ in Hong Kong

Words by Joey Gardiner

David Tickle, principal at Australian architect Hassell, has just completed a piece of research with WSP examining how already dense Hong Kong might be densified even further.

Tickle describes its conclusion, entitled “superdensity”, as a new model for vertical urbanism. It is based around the addition of giant 500m-high structures throughout the city, each accommodating thousands of homes, public spaces, parks, schools and even a hospital. These would be accessed by a 10km-long pedestrian ramp winding up the structure and an inclined supertram running from ground to summit, stopping every 80-100m.

Tickle says that in this model “people who live high in towers will be closer to public spaces and facilities. Much of life can be lived well above the ground plane and in fact, the more self-reliant this system becomes, the more effective it is.” The density of each neighbourhood could reach 2,500 dwellings, or 7,500 people, per ha.
