What a retaining wall costs in Melbourne
Much of Melbourne sits on reactive clay that swells and shrinks with the wet and dry, and that movement is hard on retaining walls — footings have to be designed for it, and a wall that ignores the soil cracks and leans within a few seasons. That makes the engineering and footing, not the facing, the real cost on anything beyond a low garden wall, and it is why a proper soil assessment matters here more than in the sandy-soil cities.
Melbourne has a deep pool of landscapers and concreters so the market is competitive on standard sleeper and besser-block walls, and a low wall on a flat suburban block is among the more affordable capitals. The cost climbs on the sloping blocks of the outer east and the hills, and anything over a metre needs a permit and engineered design, so the split between a simple garden edge and a structural wall is wide.
