Here are some design notes when it comes to modern pergola designs. The most common pergola design is to have decorative and somewhat rounded ends on the beam. The easiest way of creating a more modern pergola is to do away with the decorative ends.
Inexpensive building materials such as gravel, cinder blocks, and pressure-treated wood form the backbone of the design. Tile backboard and salvaged plywood, stained a soft blue and attached to a custom frame, give the tiny yard privacy.
