Where to start? Immediately you need to choose a place to place the gazebo, determine its size and shape, calculate the required number of building materials. Next, clear and align the site, outline the outline of the future building. You can fill in the foundation. For the gazebo, the most rational option would be a columnar foundation. The main rule is on a pillar for each corner. The pillars must be deepened by 30-60 cm, if the soil is wet-50-100 cm.
