“Until recently, we could see over the hedge and have a chat,” said Boonen. Suddenly the hedge began to grow, and the two could no longer see each other. “I admit we could have cut the hedge, but we didn’t want to,” explains Boonen. So they cut a gap in the hedge and built in a window frame, which now also serves to pass things from one side to the other: asparagus from the garden in one direction, chocolate mousse from the kitchen in the other. “Our children also use it,” Boonen said. “They crawl through, which is not really the idea.”
