Construction Timber Prices: Cost Per m³, Types & Building Uses
What Is Construction Timber?
Construction timber refers to wood used in framing, roofing, flooring, and structural components of buildings. It includes both structural and non-structural timber types. In most residential projects, you'll encounter it as the studs inside your walls, the joists under your floors, or the rafters forming your roof structure.
What separates construction timber from other wood products is that it's typically graded for strength and intended to carry loads. Even within "construction timber," there's a wide spectrum — from rough-sawn softwood for temporary bracing to precisely milled, kiln-dried hardwood for exposed beams. Knowing which category your project falls into makes a big difference in what you'll pay.
Factors Affecting Construction Timber Prices
- Timber type: Softwood or hardwood — softwoods like pine and spruce generally cost far less than oak or maple.
- Grade: Structural vs non-structural — structural grades carry certification and testing that add to the cost but are non-negotiable for load-bearing work.
- Moisture content: Kiln-dried timber costs more than air-dried or green timber, but it's more stable and less likely to warp after installation.
- Treatment: Pressure-treated timber increases durability and cost, and is often required by code for any wood in contact with concrete or exposed to weather.
- Market demand: Construction booms, supply chain disruptions, and even seasonal weather patterns that slow logging can raise prices noticeably from one month to the next.
Construction Timber Prices Per Cubic Meter
| Timber Type | Average Price (USD/m³) | Common Use |
|---|---|---|
| Softwood Timber | $250 – $450 | Framing, roofing |
| Structural Timber | $350 – $650 | Load-bearing structures |
| Treated Timber | $400 – $750 | Outdoor construction |
| Hardwood Timber | $600 – $1200 | Floors, beams |
These price ranges reflect general market averages across North America as of early 2026. Actual quotes will shift based on your region, the specific mill or supplier, the volume you're ordering, and whether delivery is included. Treated and structural grades tend to fluctuate more than standard softwood because fewer mills produce them.

Construction Timber vs Engineered Wood Prices
Traditional Construction Timber
Cost: $250–$1200/m³
Strength: Natural variation
Consistency: Variable by piece
Best for: Standard framing, traditional construction
Engineered Wood Products
Cost: $400–$1500/m³
Strength: Predictable & consistent
Consistency: Uniform across pieces
Best for: Long spans, precise engineering
Engineered wood products such as LVL and glulam often cost more but provide better strength, consistency, and longer spans compared to traditional timber. For many self-builders and smaller contractors, the decision comes down to span requirements: if you're framing a standard wall, traditional softwood is perfectly adequate and cheaper. If you're spanning a garage opening or a wide living area without intermediate supports, the extra cost of engineered lumber starts to make more sense.
Common Mistakes When Buying Construction Timber
A surprising number of first-time buyers walk into a lumber yard without checking a few basics, and those oversights can lead to wasted money or even safety issues down the road. Here are a few things that trip people up:
- Confusing "treated" with "weatherproof": Pressure-treated timber resists rot and insects, but it still absorbs moisture. It's not a substitute for proper flashing or drainage detailing.
- Buying green timber for indoor framing: Green (unseasoned) timber is cheaper but shrinks as it dries, which can cause drywall cracks and nail pops over time. For interior framing, kiln-dried is usually worth the premium.
- Assuming all structural timber is the same: Different species and grades have different span ratings. A No.2 SPF stud isn't interchangeable with a No.1 Douglas fir beam, even if they look similar on the rack.
- Overlooking delivery costs: Timber is heavy and bulky. If you're buying small quantities, delivery fees can add a surprising percentage to your total — sometimes it's cheaper to rent a trailer and pick it up yourself.
- Not checking moisture content on site: Even kiln-dried timber can pick up moisture if stored improperly at the yard. A quick look at the end grain and a feel for weight can tip you off before you load it into your build.
Storing Construction Timber On Site
Once timber arrives on site, how you store it can determine whether it stays straight and usable — or turns into a twisted, moldy headache. The goal is to keep it dry and allow air to circulate on all sides.
Stack timber on level stickers (small spacer boards) every 400–600mm along the length, and keep the stack off the ground with sturdy bearers. Cover the top with a tarp or plastic sheet to shed rain, but leave the sides open so trapped moisture can escape. If you wrap the whole stack tightly in plastic, condensation builds up inside and you'll end up with stained, sometimes structurally compromised wood. For more guidance on protecting and finishing wood in outdoor applications, our exterior wood sealing tips article covers what to do after the framing stage.
In very humid climates or during rainy seasons, consider storing timber under a temporary shelter or inside a garage bay if you have the space. The small effort of proper stacking pays off in fewer rejected boards and less frustration during framing.
How to Reduce Construction Timber Costs
- Choose softwood where possible — for most non-decorative framing, it does the job at a fraction of hardwood pricing.
- Buy standard sizes to reduce waste; custom lengths almost always carry a cutting charge and may have minimum order requirements.
- Compare treated vs untreated options carefully — only treat what actually needs it.
- Plan purchases during low-demand seasons if you have storage space; late fall and winter often bring better pricing in many regions.
- Consider local timber to save on transport — long-distance shipping on heavy material adds up fast.
- Buy in bulk for larger projects and ask about contractor or volume discounts, even if you're a DIY builder.
Frequently Asked Questions
Structural timber is graded and certified for specific load-bearing capacities, with controlled moisture content and strength testing. Non-structural timber is used for decorative or non-load-bearing applications and isn't tested for specific strength requirements. Always use structural timber for framing, beams, and other load-bearing elements to ensure building safety and code compliance. If you're unsure which grade your project requires, check with your local building inspector — they'll tell you what the code calls for in your area.
Always use treated timber for: outdoor applications, ground contact, areas with high moisture (bathrooms, basements), and termite-prone regions. Untreated timber is suitable for indoor, dry applications where it won't be exposed to moisture or insects. The 20-50% cost premium for treated timber is worth it for applications where moisture resistance is needed. One practical note: treated timber is often still wet from the treatment process when you buy it, so expect some shrinkage as it dries — factor that into your fastening and layout decisions.
Not necessarily. While hardwood offers superior strength and durability, softwood is lighter, easier to work with, and more cost-effective for most structural applications. Softwoods like pine and spruce are excellent for framing, while hardwoods like oak and maple are better for visible elements like flooring, stairs, and decorative beams where appearance matters. Many experienced builders use a mix: softwood for the skeleton of the building, hardwood only where it's seen or where extra dent resistance matters.
Timber prices typically rise during peak construction seasons (spring and summer) and may be lower during winter months. Weather conditions affecting logging operations, transportation costs, and regional demand all influence pricing. For cost savings, consider purchasing during off-peak seasons if your project timeline allows for proper storage. In practice, the swing isn't huge — maybe 5-15% — but on a full house framing package, that can add up to meaningful savings. If you're working with a smaller project, the difference might not justify the hassle of storing timber for months.
Yes, and it's often cost-effective to do so. Use structural-grade softwood for framing and hidden structural elements, treated timber for outdoor and moisture-prone areas, and hardwood for visible finish work. This approach optimizes both budget and performance. Just ensure all structural elements use properly graded timber regardless of type. One caution: if you're mixing species in a visible area (like a post-and-beam aesthetic), check how they take stain — different woods absorb finish differently and can end up looking mismatched even with the same product applied.
