East Hampton Gunite Swimming Pool Designer & Builder. This gunite swimming pool was designed and installed by Gappsi in East Hampton, NY. This pool design is a classic Hampton style with clean straight lines and bluestone coping for both the swimming pool and spill-over spa. The inside of the swimming pool incorporates corner steps and a straight bench along the 38 ft side of the swimming pool and on both sides of the spa. Bluestone coping was custom-cut 2 inches thick, 24 inches wide, and flamed. The pool coping and patio between pool and pool house was built with bluestone flagging. The gunite shell beam was shot 24 inches wide to accommodate the bluestone coping. And as a more classical look for the Hamptons area, natural grass was installed up to the edge of the pool coping.
