Tall buildings are complex, risky and visible, so it is imperative that the right team are in place to deliver any high-rise project. At the time of writing, there are 17 projects either in planning or on site that exceed 25 storeys (see figure 2), as well as many more residing in drawing format on the desks of consultants across the city as densification gathers pace.

This article reviews each stage, alongside commentary from industry voices.
