Step 23: The Tent Mod
In our county, a hard roof on a gazebo or any deck changes all the rules. The setbacks for a deck move from 4 feet to 23 feet the minute your designs include a hard roof. The result is that I had to design for a tent roof. This design started with the intention of cedar rails and a semi-permanant roof. Aside from the cost the local engineering department said NO!
As it happens, my wife found a really great buy on an octagonal garden tent (about $575 Cdn.) The problem was that the outfit selling the tent had little or no documentation and were not sure of the size. They guessed 14 feet. Does that mean 7 foot edge to edge or 7 foot radius? We bought it and found that the radius is about 13 feet 6 inches. They must include the diameter of the support poles in the 14 feet. Regardless here is where the last design mod is described.
I couldn't increase the current radius, but I could put in extensions to the vertices to support the tent poles.
Each post support is constructed of 4 pieces of wood.
Two sides at 8 inches, cutting both ends at 22.5 degrees, and
two centre pieces at 4", again with 22.5 degree cut both ends.
Assemble as shown here, glue and screw and mount at each vetrice below deck level. Fasten deck planks following the pattern of the deck with a 1-1/2 inch overhang.
