retaining wall query, page-16

In perth any retaining wall over 500mm requires council
Approval and to be designed by a structural engineer. Increasing natural ground level above 500mm could have implications
on overlooking to the adjacent property.
The design of the wall will vary according to the proximity
off any adjacent structures.
DIY is good as long as you follow a correct design.
Accountant by trade....... Be sure to put Council
Retrospective Approval (3 times the normal cost) in
Your spreadsheet. Maybe even Legals should it fail
After the next owner moves in.
When I cook I follow a recipe in a book, get
It designed and approved and building it
Should be easy.
