This lake house did not have a deck, only a ground level concrete patio that was badly broken up. We removed the patio, placed 2nd level deck supports on helical pilings, and poured a new patio. We replaced a 2nd floor window with a new Anderson patio door and then built an elevated deck. The decking was TimberTech Reliaboard with TimberTech Builder Rail. A gate to contain the family dog was also incorporated into the railing.
