Approvals?

You may need approval depending on size, structure, height and your local council or authority.
Contact your local council to confirm requirements regulations and permitted sizes vary by region. If in a bushfire prone area you may need to factor in specific requirements to meet regulations.

Site Considerations

Plan and understand your project and seek professional advice if needed
Hudson strongly suggests you make your own enquiries through appropriate bodies and professionals before any work is carried out. 

Some questions you may need to address are:

  • Is the site going to need protection from wood boring insects?
  • Has the deck got potential for water pooling or constant exposure to water?
  • Is there a need to install drainage due to potential soil erosion?
  • Are there any trees growing near the project whose roots could upset foundations or branches create a hazard?
  • Are you building on solid ground ie not reactive soil?
  • Will you need electricity, gas, water or other services to your project in the foreseeable future?
  • Are there any height considerations ie Fencing, balustrade and handrail needed to comply with codes?
  • Do you need an engineer to specify and detail construction drawings and methodology?
  • Are there Bushfire regulations I need to follow?

Bushfire Prone Areas

If you are building a decking structure in a bushfire prone area it is important to comply with building codes and the Australian Standards AS 3959. 
The standard covers construction in Bushfire prone areas and applies to new and retrofitted structures. Prior to construction, it is important to establish the bushfire attack level (BAL) of a home. Once BAL is established refer to the relevant section of the Australian Standards AS 3959 for a guide to the the steps that should be taken during construction or retrofitting of your project.
Compliance with Australian Standard AS 3959 Construction of Buildings in Bushfire Prone Areas is part of the BCA requirements for Class 1 Buildings. Click here for more info.

Bushfire Attack Levels (BAL)
These are broken down into 6 categories; BAL Low, BAL 12.5, BAL 19, BAL 29, BAL 40, and BAL Flame Zone. These levels are based on;

  • The region where you live.
  • The vegetation type around your property.
  • The distance from your home to individual vegetation types.
  • Slope on the property.

Simply click this bushfire attack level calculator link to establish the level for your construction.

Download the NSWRFS Bal Risk Application Kit. This kit provides applicants with a streamlined approach to assist them in preparing their application for a BAL Risk Assessment Certificate as part of the Complying Development process.

Some steps for you to consider in planning, construction and ongoing maintenance.
Utilise dense timbers in construction of both sub floor and decking boards. The following timber species have been tested and found to meet the required parameters without having to be subjected to fire retardant treatment: Blackbutt, Merbau, Red Ironbark, River Red Gum, Silvertop Ash, Spotted Gum andTurpentine. Composite materials are also available with a BAL up to 40.

  • Make sure that gaps between each board measures between 0 - 5mm. Any more may result in vulnerability to ember attack.
  • Enclose the subfloor of the area using mesh or bushfire resisting timbers
  • Remove leaves and twigs from the roof and gutters.
  • Utilise non combustable decorative stones and more fire resistant plant species as landscaping around the structure. Avoid flammable shrubs like eucalypts and media like woodchips as these just become fuel for a fire 
  • Keep your verandah well maintained by sealing timber with a non-combustible seal.
  • Fill in small gaps around the deck structure where an ember might be able to lodge - larger openings can be fitted with ember guards (such as perforated mesh with 2mm openings).
  • Contact your local fire authority for more information.
  • If building in Timber you may wish to download Boral's Construction in Bushfire Zones Brochure NSW or Construction in Bushfire Zones Brochure (excl NSW& SA) 

Planning and Construction

It should be noted that Hudson Building Supplies offers this information as a general guide only.
You should rely only on relevent building codes and standard industry established construction methods in any construction project. TABMA are able to provide instructions for projects. You can download the complete TABMA Decking Project PDF here. Summarised below are the general steps you may undertake in the construction process:

1 Estimate materials required and place order
2 Prepare site and locate footings/post holes using string line, line level, pegs and footing stirrups.
3 Erect deck supports – posts/poles/piers. 
4 Locate Bearers on supports and fix in place as appropriate
5 Locate joists on bearers
6 Apply a weed control measure under the deck 
7 Paint/stain (first coat), all deck framework
8 Cut to fit and install guard rail supports if necessary then cut and fix decking
9 Install railing, balusters, fascias, other trimwork as required.
10 Finish with paint/stain as desired.

Decking Board price guide

Below gives you a guide to some key chacteristics of the Decking boards
Lowest Australian Softwood Treated Decking
A less expensive option for homeowners Softwood Treated Decking usually comes from radiata pine which is a fast growing timber, sustainable and has been treated to Australian regulations.
Low-Med

Imported Hardwood Decking
Imported Hardwoods come in a variety of species, grades based on colour and durability classes. Imported from Indonesia, Malaysia and other Asia Pacific countries. Main species are Merbau and Balau which are naturally durable.

Med-High

Australian Hardwood Decking
Australian hardwood species timbers are durable, hard wearing. An Australian hardwood timber deck can be long lasting when constructed correctly. Australian Harwood decks also offer a range of colours (deep reds to blonde timbers) and grain appearance reflected in the species. FSC and Chain of Custody Australian Hardwoods are available.

Highest Composite Decking
Composite decking is highly durable and offers a low-maintenance alternative to natural timber. Composite decks can offer a time saving in construction and a consistent board length. Grain, colour, weight and dimension are all more consistent than natual timber.
