The deck is made from AC2 treated pine (non-arsenic), and is free-standing from the house (supported by 12 posts buried in concrete). Custom designed to fit the space and expectations of the homeowner. The 45 degree corners sacrifice some space, but add a more unique design and the potential for another exit point. Deck was built right over the existing concrete steps at the door. Heavy duty lattice was installed to critter-proof the underside, while a custom-built 6 foot bench was attached by the house for extra seating. Treated deck ballisters (2″ x 2″) finish the look and safety of the deck.
