Taking on a build as an owner builder is exciting, but it can also be overwhelming. One of the biggest milestones in any residential project is getting the frames and trusses sorted. This is the skeleton of your house. Get it right and everything after falls into place. Get it wrong and you are looking at delays, extra costs and a lot of stress.
If you are looking at owner builder frames and trusses NSW suppliers for the first time, this guide will walk you through how the process works and how to avoid the mistakes that trip people up.
Before we get into the ordering process, let's make sure we are on the same page about what these things actually are.
Wall frames are the prefabricated timber panels that make up the walls of your house. They are built off site in a factory to match your approved building plans. When they arrive, they get stood up, braced and fixed into position with openings for windows and doors already cut to size.
Roof trusses are the triangular structures that sit on top of your wall frames and support the roof. They spread the weight evenly across the walls and down to the foundations. Like wall frames, they are manufactured off site to your exact specifications. Common styles include gable, hip, dutch hip and valley trusses depending on your roof design.
If your build has a raised floor or second storey, you will also need a floor framing system. This includes joists, bearers and sheet flooring. Most frame and truss suppliers in NSW can include this in the same package.
In NSW, you need an owner builder permit if you are supervising or doing building work on your own home and the value of that work is over $10,000 including labour and materials.
You need a valid White Card, which is the general construction safety training required on any building site. If the value of your work is over $20,000, you also need to complete an approved owner builder course. On top of that, you need proof of land ownership, development approval and ID.
Only one owner builder permit can be issued to a person within any five year period, unless both permits relate to the same land. Get your permit sorted well before ordering materials because you cannot start building work until it is in hand.
This is where a lot of first timers feel out of their depth. The good news is that most owner builder frames and trusses NSW suppliers are set up to help people who have not done this before.
The supplier needs a copy of your approved building plans, the architectural drawings and engineering details your council or private certifier has signed off on. Their detailing team will use these to work out exactly what you need.
The estimators go through your plans and put together a detailed quote covering wall frames, roof trusses, floor systems if needed, and structural timber like posts, beams and lintels. A good supplier will give you a fixed price so you know exactly what you are up for.
Once you accept the quote, the design team creates detailed manufacturing drawings using specialist software like MiTek 20/20. Every frame and truss is engineered to meet Australian Standards and the Building Code of Australia, taking into account wind ratings, load requirements and your specific site conditions.
Your frames and trusses are built in the factory using machine graded pine, usually MGP10 or MGP12. The timber is termite treated and comes with a long term guarantee. Fabrication uses steel connector plates and is carried out by licensed fabricators.
Once manufacturing is done, everything gets delivered to your site. Most NSW suppliers offer crane truck delivery so trusses can be placed close to where they need to go. You will also receive a detailed layout plan, often colour coded, showing your carpenter exactly where each piece goes.
Timber framing costs vary depending on the size and complexity of your build. As a rough guide, expect to pay anywhere from $35 to $85 per square metre for wall frames and trusses. For a standard single storey home, the total framing package might sit between $15,000 and $25,000. Individual roof trusses typically cost between $200 and $500 each.
The biggest factors are the size of the house, the complexity of the roof, whether it is single or double storey, and the timber type. A simple rectangular home with a standard gable roof will cost less than one with lots of hips, valleys and different rooflines.
When comparing quotes from different owner builder frames and trusses NSW suppliers, make sure you are comparing like for like. Check that each quote includes engineering, manufacturing, delivery, layout plans and all structural timber. Some cheaper quotes leave out items that will cost you extra later.
Lead times for timber frames and trusses in NSW usually run between two and four weeks. During busy periods this can stretch out longer. Start the quoting process as soon as your plans are approved.
Your frames and trusses arrive on a large truck, often with a crane. If the truck cannot get close to your slab, the delivery becomes harder and more expensive. Check access requirements with your supplier beforehand.
A good supplier provides detailed plans showing exactly where every frame and truss goes. Take the time to go through these with your carpenter before installation starts. It prevents costly mistakes on site.
Unlike licensed builders who order frames all the time, you are probably doing this for the first or second time. Do not be afraid to call and ask questions. The best suppliers have experienced staff who are happy to walk owner builders through every step.
Not every frame and truss company is the same, so do your homework.
Look for a supplier that regularly works with owner builders. They will be more patient, more willing to explain things and more likely to offer the support you need throughout your build.
A guaranteed fixed price means no unexpected cost increases. The quote should cover the full scope of what is being supplied so there are no surprises.
Make sure your supplier is a licensed fabricator using engineering software like MiTek. All frames and trusses must comply with Australian Standards and the National Construction Code. Ask about the timber they use and what treatment it has.
Find out how the supplier handles delivery and whether they provide technical support during installation. Some companies take phone calls from your carpenter if questions come up on site. That kind of backup is gold for an owner builder.
Ordering timber frames and trusses does not have to be scary, even if you have never done it before. Start early, send through clear plans, ask plenty of questions and work with a supplier who understands what owner builders need.
