First of all, you must determine the location of the gazebo.To visualize the plan for the area, we recommend using pegs and rope stretched over them.Make it really is easier than you might think at first.

Imagine an octagon as a square with cut corners.Use the rule "3-4-5" (according to the theorem that all probably remember from the school, the hypotenuse of a right triangle with legs of 3 m and 4 m must be equal to 5 m (32 + 42 = 52)), to make surethat all the corners of the square lines.Do not forget to make sure that the diagonals are equal pieces.

Installation of wooden racks

Suitable for gazebos can be considered different types of foundation, starting with a concrete slab and finishing runners of timber.The first option is ideal for permanent, fundamental structures, the second is recommended if you want to move with the times its construction.Wooden beams are placed on concrete supports, as shown.
