Four quick questions. Most quotes come back within a couple of days.
Riccarton has had a lot of infill development, and infill creates retaining work. When one section becomes two or three, the new lots almost always end up at slightly different levels, and the boundary between them needs something to hold the difference.
Boundary retaining walls on subdivided Riccarton sites
The first questions are where the boundary actually is, whose ground is being retained, and what was agreed at subdivision. On recently subdivided land there is often a consent notice or an agreement that already answers it.
Worth knowing that a retaining wall is not a fence, so the Fencing Act cost sharing provisions people expect do not apply in the same way. That surprises a lot of neighbours halfway through the conversation.
Shared accessways and retaining wall surcharge
Rear lots reached by a shared drive are common here, and a wall along a shared accessway carries vehicle load. That is a surcharge and it means consent regardless of the wall height.
It also means the wall design has to allow for a vehicle that is turning or braking rather than just parked, which is a different load case again.
Retaining walls on tight infill sections
Compact sections mean limited room for a footing in front and limited room to excavate behind. On those, systems that need a wide footing or a deep reinforced soil block sometimes will not fit, and the answer moves toward a slimmer engineered wall or an anchored one.
We work that out at the site visit, because it changes both the design and the price.

Retaining walls in Riccarton: common questions
Who pays for a boundary retaining wall?
It depends on who benefits and what was agreed at subdivision. A retaining wall is not a fence, so the usual cost sharing rules do not apply in the same way.
Does a wall along a shared driveway need consent?
Yes. Vehicle load is a surcharge and that removes the exemption at any height.
