As one may be unable to define how long a piece of string is,there are so many variable factors to consider which may influence the cost of a deck.
Factors Influencing the Cost of Building a Deck in New Zealand
1. Size of the Deck
The size of your deck is a major factor affecting the cost.Larger decks obviously require more materials and labour, which naturallyincreases the overall quote.
2. Choice of Materials
The type of material you choose plays a part in determiningthe cost. Here are some common decking materials used in New Zealand:
- Softwood (e.g., Radiata Pine): Softwoods are a budget-friendly option, with costs starting at around a few hundred dollars a square metre, excluding installation. However, they do require regular maintenance to prevent wear and tear.
- Hardwood (e.g., Kwila, Vitex): Hardwoods are more durable and aesthetically pleasingbut come at a higher price, this can start from the upper hundreds to over $1,000 per square meter. However, this material may require less ongoing maintenance than cheaper options, which may save costs and time in the long run.
- Composite Decking: Made from a mix of wood and plastic, composite decking is low-maintenance and eco-friendly. Prices could range from $700 to $1,000 per square meter. Do note that prices do fluctuate depending on the supplier, location as well as supply and demand.
3. Deck Design Complexity
Adding in additional carpentry features such as stairs, awnings, balustrades and railings, planter boxes, multi-level decks and built-in seatingwill increase labour and materials and therefore the overall expense. A standard rectangular deck with no embellishments will cost less than a custom-designed deck with all the bells and whistles.
4. Deck Site Preparation Costs
The condition and level of the land where your deck will bebuilt impacts the cost. Building a deck on flat land will be more straightforwardand will therefore require less budget. However,on the contrast, if the area is uneven and requires extensive leveling,excavation, or possibly any foundation work, you can expect to pay more. Decksbuilt on sloping or uneven terrain may require extra support structures, whichwill increase the overall cost.
5. Labour Costs for Building a Deck
Labour costs vary depending on the region and the qualifications and expertise of the builder. Hiring a qualified professional ensures quality workmanship but comes at a higher price. At West & Sons Construction we are Lisenced Building Practitioners and have decades of experience.
