The GRID 30 Single Pergola kit with Base allows you to build a single structure with peaked roof that you can DIY and add onto to create structures such as a greenhouse or shed.
See sizing chart for reference of wood.
We advise consulting with your local building codes.
When customizing or adding to your build, remember to consult an engineer.
