Raised Decks in Tauranga
Tauranga is a hilly city. From the slopes above Mount Maunganui to the elevated sections in Bethlehem, Welcome Bay, and across the harbour in Omokoroa, a lot of Bay of Plenty homes sit on sections where the ground drops away from the house. That's exactly the scenario where a raised deck doesn't just make sense — it transforms the property.
What Is a Raised Deck?
A raised deck is any deck that sits more than 400mm above the ground at its highest point. That threshold matters in New Zealand because once you're above it, building consent is almost always required. Raised decks are typically supported on timber posts set into concrete footings, or on steel posts, depending on the height and loads involved. The greater the height, the more substantial the structure needs to be.
Heights vary enormously. Some raised decks sit just 500mm off the ground, essentially a high step up from a sloped garden. Others are two storeys off the ground on a steep section, effectively elevated platforms with significant structural requirements. The engineering involved in each scenario is very different, which is why having an engineer involved isn't optional on a raised deck. It's a legal requirement under the Building Code for anything requiring consent.
Is a Raised Deck Right for Your Property?
Raised decks come into their own on sloped sections where a ground-level deck simply isn't possible. If your back garden drops away from the house, a raised deck lets you step directly out from the living room onto a flat, usable surface with no steps, no slope, no awkward transition. That seamless indoor-outdoor flow is enormously valuable in a Tauranga home where the living room effectively doubles as an outdoor room for six months of the year.
Elevated decks also create privacy in a way ground-level decks can't. You're above fence height, which means you're also above the sight lines of neighbours on lower sections. For homes in tighter subdivisions, this can be genuinely transformative.
Views are another major factor. Mount Maunganui, the harbour, the Kaimai Ranges; Tauranga is full of properties with extraordinary outlooks that are only accessible from height. A well-placed raised deck can capture a view that's barely visible from ground level.
On the downside, raised decks are more expensive than ground-level decks. The structure is more complex, engineering is required, and there's more material involved. If budget is tight, it's worth having a frank conversation early about what's achievable.
Engineering and Consent Requirements
Every raised deck in Tauranga that exceeds the exempt thresholds requires a building consent from Tauranga City Council (or Western Bay of Plenty District Council depending on your location). Obtaining that consent is the homeowner's responsibility, not Klinks'. But we'll be clear with you about what your project needs so you can get the right help.
Structural engineering sign-off is a standard part of a raised deck consent application. Klinks build to the specifications provided by the engineer, and we build to code. If you have an engineer you'd like to use, we're happy to work with them. If you don't, we can recommend a couple of trusted local engineers we work with regularly who understand what deck builders need from a structural spec.
The engineering scope typically covers post sizing and spacing, footing depth and concrete specification, beam sizing, joist sizing, and connection details. It's a straightforward process for most residential raised decks — don't let it put you off. Engineers deal with these projects all the time and turnaround is usually quick.
Timber and Material Choices
The same material choices available for ground-level decks apply to raised decks — treated pine, hardwood, or composite — with some additional considerations.
Substructure
Posts, bearers, and joists are almost always treated pine or steel regardless of what the decking surface is.
Engineering
The engineer's spec will confirm the required treatment level based on the height, exposure, and ground conditions.
Composite decking
Some clients prefer composite decking on raised decks specifically because it eliminates the oiling obligation and tends to perform more consistently over time.
How Klinks Builds Raised Decks
Raised decks are one of our specialties. We've built them across Tauranga's steepest and most challenging sections, from compact elevated platforms off second-storey living rooms in the Mount to large multi-bay structures on serious slope in Bethlehem and Welcome Bay.
We start with the site visit and a conversation about how the space will be used. From there we design the deck to code, work with your engineer on the structural details, and manage the full build, including foundations, framing, decking, balustrades, steps, and any integrated features like built-in seating or a pergola above.
Frequently Asked Questions
How high can a raised deck go without special engineering?
In practice, any deck requiring consent — which means most raised decks — will need engineering sign-off regardless of height. There's no threshold above which it becomes 'special'; all consented decks need a structural specification. Height does affect the complexity and cost of the engineering, but it's not a barrier.
Do I need balustrades on a raised deck?
Yes. The New Zealand Building Code requires balustrades on any deck surface more than 1 metre above the ground. The balustrade must be at least 1 metre high and designed so children cannot climb through or over it. We'll design the balustrade to meet these requirements as a standard part of the build.
How do raised deck posts affect the garden below?
Concrete footings are set at the base of each post, which does require some excavation. The impact on the garden is usually minimal — posts are typically 100–150mm square — but it's worth considering access to the area beneath the deck. Once the deck is up, the area underneath can often be used for storage, garden beds, or just left as a shaded space.
Can I enclose the space under a raised deck?
Yes, and it's a popular option. Lattice screening, timber cladding, or planting around the base of a raised deck can turn the underneath into a tidy, sheltered storage area. This can be designed in from the start or added later.
How long does a raised deck take to build?
Depending on height, complexity, and size, typically one to two weeks. Factor in time for the consent to be granted before work starts — council processing times vary.
What maintenance does a raised deck need?
Annual cleaning, regular oiling or staining if you've chosen timber, and a periodic check of fixings, balustrades, and post bases. Posts set in or near the ground should be inspected for signs of moisture ingress. A well-maintained raised deck will last decades.
