In Lagos there's a really strong case to resurrect strong parts. Embedded in all of it are some amazing pieces of planning, amazing pieces of engineering and interaction. For instance, the campus of Lagos University is stunningly beautiful, efficient and generous, and that needs to be recognised and preserved.

Manhattan has generated a shameless architecture that has been loved in direct proportion to its defiant lack of self-hatred, has been respected exactly to the degree that it went too far.

It was a book [George Packer written on our presence in Nigeria] that was killed by the response of other people. Which sounds quite cowardly, perhaps, but it was the first manifestation of what is currently a really big issue: how political correctness defines the limits of what you can do. In that sense, it was super-exciting and maybe the most magical project we did, but at the same time fraught with mixed feelings.

There's something really interesting about current urbanism: the only model is the universal model, and there is increasingly incapacity to consider the virtues and the qualities that are there, and then to build on them. The only thing is complete transformation.

Sustainability has become an ornament.

In the end, there will be little else for us to do but shop.

Everyone is talking about sustainability and resilience, yet all that knowledge is thrown in the bin. [Lagos is] a unique case, but also a test case. It's unbelievably unique, but also it's now considered with a number of really generic opinions, generic solution, generic expectations.
