the wall surrounds the FOUNTAIN in front of the WH, NOT the WH.
your title is misleading
the wall is k-barriers, topped with plywood, dressed up to look pretty from the outside. this is commonly done around construction sites, although, usually they don't dress them up so pretty. but it is on the WH grounds, so i can understand the extra dressing.
