Deletion of Willow Row Barrow

Comment: I initially accepted this through AfC as it had some coverage in decent sources and I figured there would be more due to the claim of notability of being the first of its kind in a thousand years, however doing a more thorough  search I'm not able to find much that is not already in the article, and most of the sources are moreso about the company or the idea of modern barrows in general than this specific one. I tend to be generous with notability when it comes to topics that have little commercial potential and I mentally classified this on the "historic building"/"NGEO" side of things without considering the possible promotional aspects. But looking more closely I think the sourcing is probably not enough to pass GNG
