Hi Maureen, There are a lot of variables in cost for any wall including the cost of stone, type of construction, and jointing. This style is with reclaimed weathered New England fieldstone rounds & flats (not super expensive but not the cheapest material either), dry-laid (no mortar, not much base or footing underground because the stones can move with frost heaving cycles, requires skill for proper laying of stones to interlock for structural integrity but lasts much longer because of this) and double-faced (meaning both sides should look good) freestanding (vs. retaining), so roughly $50/face foot. Face feet are each foot of wall along the length & height that are showing on each side, so this wall has two sides to count. If it was retaining you wouldn't see the back (buried in the grade that you are retaining) so you would only pay for the front face feet. Hope this helps!
