Please review the PDF to see how you can build an amazingly sturdy custom-sized sukkah. The stability comes from the way the corners are put together. This year, my sukkah will be 8 feet long by 8 feet wide by 7 feet high. I think that 10 x 10 x 8 should be the maximum size although you can build several frames and place them together.
The photos illustrate each of the steps:
The first two photos show some of the tools I used.
The different pieces necessary for the sukkah are displayed in the next photo. There is also a close-up of what the corner elbow looks like.
The next three photos are devoted to creating the base. One picture shows how the T-shaped connectors are attached and the 4 (90 degree elbows with the one foot piece attached at each end of the elbow). The base is assembled by tamping the corner sections into the "T" connectors.
Once the base is created, the following two photos show you how the uprights looked when tamped in. One photo shows the first upright. The other photo shows all 8 uprights connected.
There were just two of us assembling the sukkah, so instead of building the entire "roof" and lifting it onto the uprights, we did it piece by piece. One photo shows the first horizontal roof piece being tamped into place and the next photo shows the corner section being added once two horizontal roof bars had been connected.
The final photo shows my friend Robin's sukkah, built according to these plans prior to being decorated. I think she found it an easy plan to follow.
To decorate: What I did for the wall covering was to take bedsheets and sew on straps at the top so the they could be tied onto the head rails. For the roof schach, you can lay bamboo poles or thinner pipes across the top and throw greenery on top of them. If the poles aren't long enough, you can lay them diagonally across the corners. The person who first built this structure stretched fabric across the top and knotted it to the head rails. Greenery can be added on top of this.
Words to the wise: If you are storing your sukkah for a year, check the glued "T"s and the corner connections. Super glue is super - but it needs to be checked over. Make sure the connections haven't come loose. If they have, just re-glue or use a stronger glue.
