Buffalo Restoration and Design’s master mason Rosolino D’Agostino, along with his crew, completed rebuilding stone walls surrounding the estate and connected to the Isabelle R. Martin House in 2003. With each area of stone wall restoration it was apparent that grade, the level of soil in relation to the walls, had risen dramatically in each location. This is largely the result of many layers of topsoil added to the areas to aid gardening in the last 75 years. At each area grade has been lowered to match its original level, except when the lowering of this level would threaten the survival of original plantings directed by Frank Lloyd Wright and documented on the original landscape plan. In some cases additional drainage work will be performed in order to accommodate the lowered grades as the estate has been plagued by inadequate drainage for many years.

Stone for the wall restorations have consisted of the original stones measured and restored to their original places within the walls or new stone where no stone remained. New stone has been hand selected by the Design committee from the many stones lying on the beach. Each stone has been selected for its size, shape, color, and distinguishing features such as a thin layer of iron fused to the rock. This technique forshadows stone effects Wright would incorporate into his desert dwelling, Taliesin West and further bonds Graycliff to its unique site. Wright incorporated stone with this fused iron in order for the mineral to give an orange cast to the surrounding stonework once placed. The fused iron appears to be limited to several hundred yards of stone fallen from the top of the cliff adjacent to Graycliff. Other distinguishing features include the extensive fossils inherent in the stone on this section of beach. Each stone has been hauled up from the beach by volunteers in order to expand the scope of this years stone restoration, as opposed to purchasing similar stone as part of the contract.

It is interesting to note that early stonework on the estate differs in execution from the stonework done even six months into the original construction. Early stonework is much more rectilinear than later stonework. The change in style of work appears to coincide with a visit by Frank Lloyd Wright to inspect the work. It seems likely that upon noticing the unique quality of the stone at this site that Frank Lloyd Wright suggested the modification in technique.
