Air-dried oak costs on average between €800 and €2,500 per cubic meter, depending on dimensions, drying time, origin, and degree of processing. For antique oak with a verifiable drying time of five years or more, the price typically falls at the upper end of that range. The sections below answer the most frequently asked questions about pricing, quality, and project planning for air-dried oak — from beams and planks to complete project deliveries.
What factors determine the price of air-dried oak?
The price of air-dried oak is determined by four main factors: drying time, dimensions, wood species, and degree of processing. A beam or plank that has spent ten years outdoors under controlled conditions is fundamentally different from wood that has dried for two years. That time is built into the price — and rightly so.
Oak that is 200 years old carries something that cannot be accelerated. The fibers have contracted, the core is fully stable, and the surface has developed a patina that only time can create. This is not an aesthetic detail, but a technical property that is relevant for both structural and decorative applications.
- Drying time: the longer the air-drying period, the more stable the wood — and the higher the price
- Dimensions: large cross-sections, wide planks, and long lengths are scarce and therefore more expensive
- Origin: antique wood from historic buildings or maritime applications has a different market value than more recently reclaimed wood
- Processing: sawn, brushed, sandblasted, or weathered wood requires additional labor and increases the price
- Grade: wood without cracks, with a consistent grain, and minimal sapwood commands a higher selection price
For an architect preparing specifications, it is useful to factor in these considerations during the design phase. The choice of a particular processing level or minimum drying time has a direct impact on the budget — regardless of whether the project involves beams, floorboards, or wall cladding.
What is the price difference between air-dried and kiln-dried oak?
Air-dried oak is in most cases more expensive than kiln-dried oak, but that price difference reflects a fundamental difference in quality and application. Kiln-dried wood is brought to the desired moisture content in an oven within a short period of time. Air-dried wood achieves the same result over years, which preserves the cell structure and increases stability.
In practice, this means that air-dried oak moves less, shrinks less, and is more resistant to fluctuating humidity levels. For structural applications, large spans, or high-end interiors, that difference is significant. Kiln-dried wood is a good choice for applications where fast availability and a lower price outweigh the need for maximum long-term stability.
In practice, the price difference ranges from twenty to sometimes fifty percent, depending on dimensions and wood type. For projects where the wood remains visible and must stay stable over decades, air-dried oak is in most cases the more logical choice — even when the initial cost is higher.
Why do prices for antique oak vary so widely?
The price range for antique oak is broad because no two lots are identical. Antique oak is by definition not a standardized product. Origin, age, dimensions, grade, and condition vary from piece to piece, lot to lot, and supplier to supplier. This makes direct price comparisons difficult and sometimes misleading.
A lot of old oak beams twelve meters in length with a cross-section of 25 by 30 centimeters is simply scarcer than shorter, smaller beams. Scarcity drives the price up. The same applies to wood that is verifiably sourced from a historic building, or wood that has been air-drying for more than five years and is therefore immediately suitable for demanding structural projects.
Grade also plays a major role. Wood selected for minimal sapwood, straight grain, and limited cracking commands a higher price than ungraded wood from the same lot. For a developer or contractor who requires consistent quality across multiple lots, that selection process is not a luxury — it is a necessity.
How is the quantity of oak calculated for a project?
Oak is calculated in cubic meters. The formula is straightforward: width (in meters) × height (in meters) × length (in meters) = volume per piece. Add up all pieces for the total volume. That figure is the basis for any quotation — whether it involves beams, planks, or a combination of both.
- Determine the required cross-section and length for each element based on the structural design
- Calculate the volume per beam or plank in cubic meters
- Add up all volumes to arrive at the gross required volume
- Add a waste allowance of five to fifteen percent, depending on grading requirements
- Use this total as the basis for the quotation request
A common mistake is forgetting the waste allowance. With antique wood, not every piece in every lot is immediately usable for the intended purpose. Ordering exactly to volume without any margin risks running short. A good supplier will already factor this in during the quotation stage.
For complex projects involving multiple wood types or mixed dimensions — for example, beams combined with old oak planks for flooring or wall cladding — it is advisable to provide a detailed cut list. This makes the quotation more accurate and prevents misunderstandings about what will be delivered.
When is air-dried oak the right choice for a project?
Whether air-dried oak is the right choice depends on the application, the desired appearance, the structural requirements, and the available budget. There is no single definitive answer, but there are situations in which air-dried oak is in most cases more logical than the alternatives.
Air-dried oak is often a good choice when:
- the wood will remain visible and the character of the material is part of the design
- the project involves large spans or structural loads where long-term stability is required
- the project has a historic context and the authenticity of the material must be verifiable
- the client expects a long service life with minimal maintenance
- the wood will be used in an environment with fluctuating humidity, such as unheated spaces or semi-outdoor applications
Kiln-dried or freshly sawn oak may be the preferred option in other situations, particularly when lead time and price carry more weight than maximum stability. The choice is project-dependent, and a good supplier will help weigh those factors based on the specific situation.

What should a quotation for air-dried oak include as a minimum?
A quotation for air-dried oak must include at minimum the wood species, drying time, dimensions, grade, degree of processing, and lead time. Without this information, a quotation cannot be meaningfully compared with other offers and provides insufficient basis for execution.
A reliable quotation includes at least:
- the exact wood species and origin, preferably with a verifiable drying time
- the dimensions per piece or the range within which delivery will be made
- the grade or selection criteria that have been applied
- the processing condition: rough, sawn, brushed, or otherwise
- the total volume in cubic meters and the price per cubic meter
- the expected lead time and any conditions applicable to custom work
- the terms for returns or replacement in the event of substandard quality
A quotation that states only a total price without specifications offers insufficient protection for the client. Particularly with antique wood, where variation between lots can be significant, transparency about selection criteria is essential. Always request photographs or visit the yard to assess the wood in person before placing a final order.
