A hillside city changes the brief before design starts.
Dunedin's landscaping briefs split along a line that has nothing to do with budget: which part of the city the section sits in. A terraced quarter-acre in Roslyn, Mornington or Māori Hill behaves nothing like a flatter South Dunedin bungalow section, and a harbour-facing property on the Otago Peninsula behaves differently again. Aspect, wind exposure and how steeply the land falls away from the house change almost every early decision, from where machinery can actually work to which parts of the garden will get used through a cool, wet Dunedin winter.
Dunedin City Council also expects a defined stormwater outfall and enough design information to assess catchment and devices before it will sign off added hard surface, and much of the hill suburbs sit within mapped natural hazard considerations for slippage, erosion, subsidence or inundation. Neither of those is a formality here the way it might be on a flat, low-risk section elsewhere — they shape what a landscaper can commit to before council input is confirmed.
01 · What actually shapes a Dunedin brief
Six site facts to establish before scope is set.
Before comparing paving, planting or retaining systems, establish these facts about the specific property. On a hill city they decide more of the brief than any material choice will.
Which hill you're on
Roslyn, Mornington and Māori Hill sit on steep, terraced land where access and retaining dominate the brief; St Clair and Andersons Bay add coastal wind; South Dunedin is flatter but carries its own flood-context checks.
Access from the street
Stairs, steep drives and narrow hill streets can rule out a full-size digger and truck, pushing work toward smaller machinery, hand-carting or a staged material delivery plan.
Wind and aspect
Peninsula, hill and coastal exposures can be severe, while a sheltered gully two streets over behaves completely differently — don't assume the same wind strategy suits a whole suburb.
Stormwater outfall
Council wants a defined, appropriate outfall and enough catchment and device information before consenting new hard surface — this should be identified early, not left until drawings are near-final.
Hazard considerations
Slippage, erosion, subsidence and inundation are council-listed natural hazard considerations across parts of the hill suburbs, and can bring geotechnical input into a brief that would otherwise not need it.
South Dunedin flood checks
Low-lying South Dunedin, streams and some coastal settings need address-level flood-context checks before finished levels and drainage strategy are locked in.
02 · What moves the number in Dunedin
Access and slope move the price more than finish does.
A considered plan that respects the slope is often cheaper than a premium finish forced onto a poorly staged hill section.
Planning noteResolving the outfall point and any hazard question before pricing individual finishes prevents a mid-project redesign that costs far more than the week it takes to check.
03 · A Dunedin project, worked through
A terraced section in Mornington.
A terraced section in Mornington
A quarter-acre section falls close to two metres from the street to the back boundary, with the driveway sitting on a grade that limits machinery to a mini-excavator working off the existing concrete. The brief includes a new terrace off the kitchen, a path down to an established vegetable garden, and planting to replace an overgrown bank. Sequencing starts with confirming the stormwater outfall with council and checking whether the property falls within a mapped hazard area, since a retaining element is already implied by the level change the terrace needs. Once that's resolved, a low block wall creates the flat terrace, drainage is run behind it and tied into the confirmed outfall, and the path and planting follow last — with species chosen for the site's actual aspect rather than a generic Dunedin palette, since the terrace sits in full sun while the lower bank is shaded most of the afternoon.
04 · Before requesting Dunedin quotes
A practical pre-brief checklist for hill-city sections.
- Confirm access width and gradient from the street, especially for hill sections in Roslyn, Mornington, Māori Hill or similar terraced suburbs.
- Check whether the property sits within a mapped slippage, erosion, subsidence or inundation hazard area before scope is finalised.
- Identify a stormwater outfall point and confirm what catchment and device information council needs to see.
- If the section is in South Dunedin, or near a stream or the coast, get an address-level flood-context check done early.
- Record actual aspect and wind exposure for each part of the site — a sheltered gully and an open hilltop on the same street need different decisions.
