Construction was just the same as before for the rectangular buildings. The painted building in the centre of the lower image was made from a plastic container that some tennis balls were sold it, with half a ping pong ball stuck on top, with some carbon strips added. It was originally built free-standing, which is why it is already painted. I also cut it down in size to fit the scene.
The domed tower at the right of the upper image is a cardboard tube with half a ping pong ball on top, whilst the dome on the building beside it was cut from a polystyrene ball (packed of these can purchased from Amazon for not too much).
The building to the left of that was built from a plastic wine glass with the base removed, and a small ball on top.
Next stage will be painting...
