A detailed design will include all of the above work with more info on the specific elements of each system, for example down to the detail of positioning of each tree in an orchard including variety and rootstock etc.
This level of design can suit small garden designs, and any customer looking for a full design to be implemented.
For large sites some of the detail can only be worked out during installation as more knowledge is inevitably gained during earthworks on site.
You can choose this as an add on if you like the patterning design and want to go ahead to installation.
