Vertical mixed use communities, a compact city model?
Abstract: Cities have advocated more compact development patterns to address the need to accommodate a burgeoning urban population. One such compact model is the vertical mixed-use (VMU) development. However, its development and implementation are generally perceived to be complicated in terms of unfavorable regulatory and development controls, higher construction cost, staging as well as funding complexities.
We examine the growth patterns and development trends of vertical mixed-use developments in Brisbane, looking for evidence that the vertical mixed-use model can promote sustainable futures for Australian cities. We also reviewed existing urban policies, codes and regulations. Our results indicate a slow but growing trend towards the development of VMUs within Brisbane CBD as a result of statutory policies, which encourage the integration of mixed-use zones within activity centres. Using Hoppenbrouwer and Low’s framework we identified and profiled thirteen VMUs. Our results strongly suggest the rampant presence of single function vertical structures (86% of 418) within Brisbane CBD. Only 1.7% of the vertical structures identified accommodated three and 11.9% two uses. We then surveyed the perception of developers in terms of potential and significant barriers to VMU development.
