Four quick questions. Most quotes come back within a couple of days.
Westmorland is newer than the suburbs below it and it was developed by cutting and filling platforms into a fairly steep slope. That gives it a specific character: most sections have a cut face on one side and placed fill on the other, and the wall requirements on each side are completely different.
Cut and fill retaining walls on the same Westmorland section
A wall on the cut side is holding undisturbed loess. A wall on the fill side is holding material that was placed when the platform was formed. They have different design parameters and different failure modes, and they should not be priced the same way.
Where the fill was engineered and tested at subdivision, that is a good starting point. Where it was not, it needs investigating.
Why surcharge puts most Westmorland retaining walls into consent
Westmorland sections are steep enough that driveways are benched into the slope and houses sit close to level changes. That means a very high proportion of walls here carry a surcharge, which removes the Schedule 1 exemption regardless of height.
We tell people this at the site visit rather than letting them budget for an unconsented wall that cannot legally be built.
Views, finish and choosing a retaining wall you will look at daily
People built up here for the view, and the walls tend to be looked at. That pushes the answer toward stone faced block, board formed concrete or a well detailed segmental system with a glass balustrade rather than grey block.
Structure first, then finish. The core does not change, and the facing is where the decision is.

Retaining walls in Westmorland: common questions
Does my Westmorland wall need consent?
Very often yes, because the sections are steep enough that a driveway or a house usually sits above the wall, and that surcharge removes the exemption at any height.
Why does the cut side price differently to the fill side?
Because one is holding undisturbed ground and the other is holding material somebody placed there. They are different design problems.
Why do so many Westmorland walls need consent?
Because the sections are steep enough that driveways get benched into the slope and houses sit close to level changes. That means a very high proportion of walls carry a surcharge, and surcharge removes the Schedule 1 exemption regardless of the wall height.
Can a Westmorland retaining wall look like more than grey block?
Yes, and it usually should, because these walls are looked at from the house every day. Stone faced block, board formed concrete or a well detailed segmental system with a glass balustrade all give you the engineering underneath and a face worth looking at.
