SK53 OSM
Canning Circus @z19
It's all Derick Rethans' fault that all these building are here on OSM. I knew that Derick had rendered London at z19 and z20 so I thought I'd try it too.
I ran into a problem zooming into z19 of my local tiles but eventually solved it. It just required adding numZoomLevels to the options for the layer.
A number of features make it obvious that the default mapnik style requires quite a bit of work at this level (roads in general are too thin). Many polygons also lack refinement. I chose this area because most of the buildings had been done carefully (following Derick's example).
