Use hidden fasteners for a more professional and clean-looking deck surface. Consider laying the deck boards in patterns instead of simply nailing them perpendicular to the joists. Diagonal decking, chevrons or other patterns can be quite attractive. Remember to space joists properly to support the decking. For example, diagonal decking requires a joist spacing of 16 inches on center. The right choice of amenities can transform a simple deck into an outdoor room enjoyed by the entire family. Consider adding built-in seating, tables, counters and storage areas. If you will be using your deck for dining, consider adding a grill, outdoor sink or other cooking amenities. You can create cozy conversation areas with benches and fire pits. Redwood decks and spas are a natural combination.
