Our back deck surface was getting pretty old so we decided to replace the surface and at the same time expand the deck to give ourselves more room. We looked at several designs and adding half an octagon to the long side seemed like the best option. This design gave us a total of 244 square feet, which is only about 60 sq ft more, but makes the deck a lot more functional. We also wanted maintenance free so we used the same Veranda material we had used four years ago on the front deck, which only requires an occasional cleaning.
The original framing on the back deck had 24" centers with cross framing every 24" to support a basket weave decking layout. We decided that the new decking would run length wise and I would need to add additional framing to comply with the maximum 16" O.C. spacing limitations for the Veranda material. We also added vinyl railing and a matching skirt board cover to dress it up a bit. We're debating whether to enclose the area under the deck to provide some storage and to hide the supporting posts and braces. I used a hidden fastener system called Phantom 2 and some angle clips and pocket holes on the underside so there are no fasteners or holes on the upper deck surface.
THe next project will be to resurface teh picnic table.......
Our dog really like the new area and spends as much time out there as he can watching the neighborhood (mostly fields and woods.)
Thanks for viewing.
