Solving the Stack
With the predicted demise of large-scale single usage building formats, the shift towards more sustainable mixed-use typologies will continue, especially as increased urban land values continue to sky-rocket in price.
Commercially, mixed-use buildings are more complex to stack up in comparison to single use buildings. The fundamental economic restrictions is efficiency, as the increased cost of building is often passed onto the tenant.
With mixed-usage buildings, the biggest culprits for drops in efficiency are lifting and structure, as lift shafts pass through adjoining programmatic zones, which create an overall inefficiency in area throughout the stack of the building.
With new lifting technology and very careful lift-stacking, this impact can be minimised. Core design is more critical than ever with most supertall buildings having less area at the pinnacles, which is counter-intuitive as this is where the greatest property value exists. The future of supertalls and mixed use-developments will intelligently solve lifting efficiencies to increase the overall distribution of high-value units throughout the vertical community.

Chongqing Tall Tower
The stacked form of the Chongqing Tall Tower creates an iconic architectural form with a mixed use function. The building’s top section will house the Ritz-Carlton hotel with 280 rooms, with high end apartments in the mid-section and offices in the lower section, over a ballroom and retail podium of 10 levels, with basement car parking and the existing metro station underneath.
A major design challenge in this project is the complexity of linking into the existing podium conditions, and the vertical stack of different functions in the super tower, joining with an existing retail podium and fully redeveloping an existing hotel structure into a new 120-meter luxury apartment building of 240 units.
