Timber & Composite Decks

Looking for a deck builder in Auckland? Greyson Builders design and build custom decks for homeowners across Auckland - from small courtyard decks to large entertaining platforms with stairs, balustrades, and integrated fencing.

We use quality materials, build to last, and make the whole process straightforward from first quote to finished deck.

Custom Deck Building Auckland

A well-built deck transforms how you use your outdoor space. Whether you're after a large entertaining area for summer gatherings, a wraparound deck to make the most of your section, or a simple raised platform off the back of the house, we'll build it properly and to a standard that holds up to Auckland's weather year after year.

We handle everything — design input, material selection, consent advice, and the full build — so you don't have to coordinate multiple trades or figure out council requirements on your own.

As a Licensed Building Practitioner, all our deck builds are compliant with New Zealand building standards. Where building consent is required, we manage that process as part of the job.

Timber Decks Auckland

Timber is the most popular choice for Auckland decks - and for good reason. It's versatile, looks great against most homes, and when built and maintained correctly, it lasts for decades.

We work with a range of timber species suited to the New Zealand climate, including treated pine, hardwoods, and locally available options depending on your budget and aesthetic. We'll talk you through the pros and cons of each and help you choose the right material for how the deck will be used.

    • Treated pine

    • Kwila (Merbau) hardwood

    • Fijian Mahogany hardwood

    • Garapa hardwood

    • Purpleheart hardwood

    • Vitex and other durable hardwoods

    • Recycled and reclaimed timber options

Composite Decking Auckland

Composite decking is an increasingly popular choice for homeowners who want the look of timber with significantly less ongoing maintenance. It won't rot, splinter, or need annual oiling — making it a smart long-term investment, particularly in exposed or high-use locations.

We supply and install quality composite decking boards and can advise on the best products for your budget and situation.

    • Low maintenance - no oiliness, staining or sealing required

    • Resistant to rot, moisture, and UV fading

    • Consistent appearance over time

    • Wide range of colours and finishes available

    • Suitable for pool surrounds and coastal properties

Deck Replacements & Upgrades Auckland

Got an old deck that's seen better days? We assess, advise, and rebuild — whether that means replacing rotten boards and joists, reframing from the posts up, or taking the whole thing down and starting fresh with a better design and quality materials.

We'll give you an honest assessment of what's salvageable and what needs to go, and quote accordingly. No inflating scope to sell unnecessary work.

    • Full deck demolition and rebuild

    • Subframe and joist replacement

    • Board replacement and re-decking

    • Balustrade and handrail upgrades

    • Stair replacement and reconfiguration

Frequently Asked Questions - Deck Building, Auckland

  • Not always. In most cases, decks under 1.5 metres above ground level and not attached to the primary structure don't require building consent. However, raised decks, decks attached to the house, and those with balustrades often do. We'll advise what applies to your specific situation as part of the quoting process.

  • A standard timber deck typically starts from around $15,000–$25,000 for a mid-sized build, depending on size, height, materials, and complexity. Larger decks with stairs, balustrades, and composite materials will be higher. We provide detailed fixed-price quotes so you know exactly where you stand before committing.

  • Most deck builds take 1–3 weeks once construction begins, depending on size and complexity. Consent processing (where required) adds time before we can start on site. We'll give you a clear timeline during the quoting stage.

  • It depends on your budget and priorities. Treated pine is cost-effective and widely used. My personal favourite is Kwila, it looks great and has the best durability. Composite is the lowest-maintenance long-term option. We'll walk you through the options and help you choose what's right for your home and how you'll use the space.

  • Absolutely - we often combine deck and fence builds into a single project, which is more efficient and ensures everything integrates well. Many of our clients have us tackle both at once.

  • We build decks across Auckland including West Auckland, North Shore, Rodney, and the Hibiscus Coast. Give us a call to confirm we cover your area.

  • Yes - this has been a really popular choice our clients recently. The timber screen is a great option to provide privacy for when you’re entertaining guests on your deck.
