Yes, my photos are recent.

But about the roadworks - I mean for the adjacent road and the sidewalk. Those works ended and only those were planed for now.

I don't know yet about any scheduled construction on this previously-grassland itself.

Which is needed to use greenfield according to:

So probably surface = ground;grass would be safer to use for now.
