With the right trees and the right markets, these woodlands could produce long-lasting timber products for buildings, homes and furniture.\n\nIn this blog we will cover some high-value wood products from UK woodlands, including timber for construction, cladding, decorative timbers, hardwood flooring, joinery and furniture making.\n\n## How to grow high-quality timber\n\nProducing high-value timber begins long before a tree is harvested. The quality of the final product is largely determined by silviculture – how a woodland is established and managed over time.\n\nEarly interventions are particularly important. Appropriate planting densities and timely thinning help ensure the best trees have enough light and space to grow straight and develop strong stems. Selecting and retaining promising individuals concentrates growth on trees most likely to produce high-quality logs. Regular, carefully planned thinning also helps improve the stability of the stand to wind and storms, ensuring trees are both productive and resilient.\n\nPractices such as formative pruning, brashing and high pruning can further improve timber quality by removing lower branches while trees are young. This reduces the number and size of knots in the stem, allowing clearer timber to form as the tree grows.\n\nThe final factor to consider in growing high-quality trees, especially hardwoods, is protecting them from deer and grey squirrels. Deer can damage young trees and strip bark from valuable lower stems. Grey squirrels usually cause problems later on, by stripping bark and killing the tree’s crown, which negatively impacts its timber value. Effective management of both is essential to produce quality timber.\n\nOver time, these relatively simple management decisions can significantly increase the proportion of timber suitable for structural, joinery and specialist markets.\n\n18-year-old birch after its first thinning.\n\n## High-value wood product features\n\nStraight stems, good form, sufficient diameter and the visual appearance of the grain all influence what your trees will be suitable for. Not every tree will meet these standards and quite often only the first few meters of a tree stem will be suitable for high-value products. However, if your woodland does have trees with the right features, this can significantly increase its value.\n\nWell managed woodlands producing high-value timber also benefit the environment. When these trees are used for construction, flooring or furniture, they continue to store carbon over their lifetime.\n\nHigh quality oak in Glinger Woods, Cumbria.\n\n## **Construction timber and the opportunities for UK-grown timber**\n\nTimber is an integral material used in UK construction and its use is expected to grow further. The government’s timber in construction roadmap aims to increase the use of sustainable timber in construction, as part of its transition to a low-carbon construction sector.\n\nIn 2024 the UK’s apparent consumption of wood and wood products (domestic production plus imports, minus exports) was approximately 48 million cubic metres – yet around 75-80% of the timber we use is imported.1 This reliance on international supply means there is growing interest in increasing the use of UK-grown timber, creating opportunities for well managed woodlands.\n\n## The physical requirements for timber in construction\n\nTo be suitable for structural use, timber must meet the right physical requirements. Construction timber usually comes from straight, clean sawlogs with minimal knots or other defects. Most construction timber, whether from the UK or abroad, is produced from softwood species such as spruce, pine, larch and Douglas fir.\n\nCentral to using timber in construction is the grading of timber to assess and quantify its structural properties, to ensure the right timber is used where it is required to carry structural loads.\n\nTimber can be visually graded, where certified experts assess the knot size, grain direction and other characteristics that influence strength. However, in most large-scale sawmills, strength grading is an automatic and mechanical process which assesses the stiffness of planks passing through a grading machine to assign a structural class.\n\nSoftwood structural timber is classified into ‘C’ classes, where higher numbers indicate a stronger timber. While C24 is often considered the default grade for construction timber, most C24 timber is imported with UK-grown timber most commonly graded at C16. Importantly, C16 is suitable for most structural applications, which means homegrown timber has a strong role to play in the UK construction market, and can displace imported timber if specified at the design stage.\n\nPerson visually checking sawn timber quality.

Softwood boards are graded in the 'C' classes based on standards set out in BS EN 338:2016 structural timber – strength classes.\n\nHardwoods have their own structural classification system known as 'D' classes, such as D24 or D30. In practice, hardwood timber is often assessed for slightly different markets. Hardwood is not primarily sold as standardised planks and beams with a standardised strength grade, because it is often used in architectural, decorative or bespoke structural applications, where the individual character and dimensions of the timber can matter as much as the strength.\n\nFor example, large straight oak stems can produce long, straight beams that are difficult to replicate with smaller material. These timbers are often used as exposed features within buildings forming roof structures or dramatic internal frames where the natural character of the wood becomes part of the design.\n\nThis is where visual grading plays an important role. Experienced sawmillers will process each log and board based on what they believe the best end use to be, whether structural, joinery or flooring. Large straight stems with few knots and defects may become oak beams or timber frames, whilst attractive boards from species such as sycamore, cherry or beech may be used for interior joinery and furniture.\n\nFor woodland owners, this means well grown hardwood trees can supply a range of high value markets where both the structural qualities and natural beauty of the timber add value.\n\nThe challenge can be growing trees to the right standard to take advantage of these markets. Most trees suitable for these high-value markets have benefited from careful management in the past.\n\nHigh quality, large diameter Douglas fir timber.

Timber cladding has become increasingly popular in modern architecture because it provides a natural appearance, performs well in low carbon construction and can last for decades when the right species and processing methods are used.\n\nFor cladding applications, timber needs to be stable, straight and relatively defect free from knots and stains, while able to withstand moisture and exposure to the elements. Traditionally, this has meant relying on naturally durable species such as oak, sweet chestnut and larch because of their inherent durability without need for chemical treatment.\n\nHowever, advances in processing are opening new opportunities through thermal modification. In this process, timber is heated in a controlled environment to temperatures of around 200 degrees Celsius, altering the wood’s internal structure. This reduces the moisture absorption and significantly improves durability and stability.\n\nThermal modification allows species such as ash, sycamore and poplar, which would normally be unsuitable for exterior use, to perform well as cladding and external joinery. This technology provides significant opportunities for high-quality tree species, which have in the past struggled to access large high-value markets.\n\nTimber cladding in use on the Bwlch nant yr Arian Visitor Centre.

Species such as oak, cherry, walnut, sycamore, beech and ash can all be used by furniture makers, joiners and woodturners.\n\nIn these markets, the visual character of the wood can be just as important as its structural properties. Features such as tight grain, colour variation and distinctive figuring (decorative patterns in the grain of the wood) can significantly increase the value of a log.\n\nSought after examples include burrs, where the tree produces a complex swirling grain pattern, or ‘pippy’ oak, where clusters of small knots create a decorative texture. Other figure patterns, such as ripple grain are prized for high-end furniture, veneers and decorative panels.\n\nBecause each tree is unique, high-quality hardwood logs are often marketed differently to standard timber. Exceptional stems are frequently sold individually at roadside, allowing specialist buyers to inspect the logs. Whilst local markets can exist for these high-value products, national or regional auctions are often used to gain access to more buyers.\n\nThe Forest Research and Grown in Britain price size curves report provides a guide to the relative value of different hardwood species and grades of logs. As a general guide, the value of these high-value hardwoods can be over £400 per cubic meter, compared to around £70-150 per cubic meter for other high-value, but more common species, such as Douglas fir.\n\n## **New opportunities for UK timber**\n\nAs interest in low carbon construction grows, new technologies are creating opportunities to make better use of UK timber in buildings. Engineered timber, such as glue laminated timber (glulam) and finger jointed timber, allows smaller pieces of wood to be combined into strong structural components. These processes make it possible to use timber or species that might otherwise be too small or variable for structural use.\n\nProjects are already demonstrating what these developments could mean for UK supply chains. The Creating Sustainable Quality Homes project by Veya Homes explores how homes can be built using timber grown and processed exclusively in the UK. New developments by pioneering house builder GS8 are leading the way in sustainable living and feature a high percentage of timber including Grown in Britain certified larch cladding on the building exterior and structural C16 within.\n\nThe COP26 House, designed by Roderick James Architects, is another example where almost all the building uses C16 timber (Sitka spruce), certified by Grown in Britain. This house was built as an exemplar net-zero carbon house for COP26. It was also designed to be deconstructed and reused after the event and now has a new life on a Scottish estate.\n\nThese projects demonstrate a clear direction of travel. By combining active woodland management with modern timber processing, there is increasing potential to turn more UK-grown trees into high-value structural timber for the buildings of the future.\n\nDiscover more on how to produce wood products from your woodland on Woods Mean Business and Trees to Timber.\n\n  1.
