I was using the high setting and was using the photo utility - I was not ussing the latest reder utility.
The file size is quite large (trees etc are quite large 'furniture' items) and if I used the anvanced renering tool, the programme would quit or else the render programme would not create anything.
Here is an example:

(In this picture, the shadows indicate multiple light sources and the resulting render is overall quite dark.
The shadows make it somewhat difficult to easily see the buidling.)
