Lost in Space? (DS286)

A couple of weeks back I blipped an old electrical connection box which looks to have been the supply to something being built in the middle of the field.   Today's blip is the 'something'.

Still no idea what it is though - there is a hint of a pitched roof with a dormer style window but there are so many trees blocking the view it is difficult to tell.  It is in the middle of a reasonably large field so quite lost in space.

Thanks to Marlieske for hosting.
