Hardwood and composite decks, including elevated decks on sloping and harbourside blocks, built as part of an outdoor living space.

A well-built deck turns a steep or uneven block into usable living space. On the North Shore, that often means building out from a back door over a fall in the land, around a sandstone outcrop, or beside a pool where paving won't sit level. We build decks in Australian hardwoods such as spotted gum and blackbutt, and in capped composite boards for owners who want less ongoing upkeep. Every deck sits on a properly engineered subframe, either treated timber or galvanised steel, set on concrete footings sized for the soil and the span.
Local conditions decide a lot of the detail. Harbourside and waterfront homes deal with salt air that corrodes standard fixings, so we use marine-grade stainless steel screws and hidden clips there. In shaded gully blocks around the Upper North Shore, decks can stay damp for days after a summer storm. Good ventilation underneath, board spacing that lets water drain, and a subframe kept clear of the soil are what stop rot and mould from taking hold. Many of these properties also sit on bushfire-prone land, and we choose board species and construction details to suit the site's bushfire attack level.
Most of our decks are part of a larger outdoor project. A deck might step down to a pool surround, connect to sandstone paving, or sit under a covered roof so you can use it year-round. We often pair decking with pergolas and outdoor structures for shade, and with pool landscaping where a timber or composite edge softens the look of the pool area. One team manages the whole scope, so levels, drainage and finishes line up across every surface.
From site levels and footings to final oiling and balustrades
We walk the site, take levels and note the fall of the land, existing rock, drainage paths and how the deck meets the house. From there we lay out the deck shape, board direction, step positions and how it connects to paving, pools or garden beds. We also check whether council approval or a bushfire assessment affects the design.
We set out and dig footing holes, pour concrete and fix stirrups or steel posts to suit the soil and the deck height. Bearers and joists go in next, checked for level and spaced to suit the chosen boards. On damp or shaded sites we keep timber well clear of the ground and allow airflow underneath.
Boards are laid with even gaps for drainage and timber movement, then fixed with stainless screws or hidden clips depending on the material and site. We cut and finish board ends cleanly around posts, steps and pool edges. Picture-frame borders and breaker boards are set out to avoid awkward joins.
Hardwood decks are sanded and coated with a penetrating oil, while composite boards are cleaned and checked. Balustrades, stairs, lighting and any built-in seating are installed and tested. We then walk you through care and cleaning so the deck keeps looking right.
Practical outcomes for steep blocks, pool areas and coastal homes
A deck creates a flat, level area where the land falls away or rock makes paving impractical. That space can become a dining spot, a lounge area or a link between the house and the pool. You get more of your block working for you.
Correct fixings, ventilation and board spacing help limit corrosion, cupping and rot in coastal and humid conditions. That means fewer loose boards and stained screw heads over time. Your deck stays safe and solid underfoot through wet summers.
When the deck, paving, pool surround and pergola are planned as one, the levels meet cleanly and the materials suit each other. There are no awkward steps or mismatched finishes between areas. The whole backyard feels designed rather than added piece by piece.
North Shore blocks often have sharp falls, sandstone shelves and tight access. We plan footings and subframes around these conditions rather than forcing a standard design onto the site. That keeps the deck stable and the build practical.
Waterfront and harbourside decks need marine-grade fixings and good ventilation to hold up. We specify these details from the start. You avoid rust streaks and failing screws later.
We build decks as part of complete landscape projects, alongside retaining walls, pool surrounds and outdoor kitchens. One team manages the levels, drainage and finishes across the whole job. You deal with one point of contact from design to handover.
Picture-frame edges, clean stair nosings and hidden fixings make the difference on a premium deck. We plan board layouts so joins and cuts sit neatly. The finished deck suits the quality of the home it's attached to.
Common questions answered
Hardwood such as spotted gum or blackbutt gives a natural look and can be re-sanded and re-oiled over its life. Composite needs less upkeep and won't need oiling, which suits busy households and pool areas. We look at sun exposure, bushfire requirements and how you'll use the deck before recommending one.
The main factors are deck size, height off the ground, board material, subframe type and site access. Steep blocks, rock that needs to be broken out for footings, and extras like stairs, balustrades and lighting also add to the scope. We give you a detailed quote after inspecting the site.
It depends on the size of the deck, the height and complexity of the subframe, any council approvals and the weather. A simple ground-level deck moves faster than an elevated deck on a steep block. We'll outline the stages and expected sequence once the design is confirmed.
Some decks fall under exempt development rules, while others need a complying development certificate or a development application. Height, size, distance from boundaries and bushfire-prone land all play a part. We check the requirements for your property during the design stage.
Decks in full sun or near salt water lose their finish faster than shaded decks. A good sign is when water stops beading on the surface and the timber starts to look dry or grey. Regular sweeping and keeping leaves and pots from sitting on the boards also helps the finish last.
