A Pergola on Existing Unilock Patio


A Pergola designed atop a Unilock stacked wall, (glued together). This very substantial and rigid pergola will stay put for decades even though the wall was not designed to support a pergola. This pergola would sit directly on a patio without fastening and would not move. When you have a complex or challenging pergola project, get in touch with Gardenstructure!

“Can you install a pergola on our existing interlocking stone patio”?  We hear it all the time. This was a unique case. They wanted a pergola to sit within a stacked wall of unilock stone. These are basically interlocking stones that are glued together. Not much lateral strength to something like that. You can’t just build your typical pergola and expect it to last past the first windy day.  In this case we had to create a self bracing pergola that would be heavy enough to stay put, and structurally rigid enough to not rack the block apart. The large braces are made of marine plywood– more pictures coming once the stain is applied!
