That's the diving/fishing dock poking into the emerald lake there to the lower right. The brown field mid-right was recently seeded for a winter crop. And in the center is the fully restored barn they've converted into a full service event site. They successfully hosted a first wedding the weekend before this series was photographed.
If you look closely just to the left of the tree - see the lavender covered trellis? Perfect for bridal pix from every angle - especially with the photographer's back to the barn and the pond, fences and the heart carved into the hill shown in Series 5 behind the wedding party.
It feels like a romantic chic-flick movie set.
