Inside the Studio: How We Source and Finish English Walnut
The journey from tree to table: materials, sourcing, and the craft of finishing.
English walnut does not ask to be noticed. It does not announce itself with vivid grain or dramatic figuring the way some timbers do. It earns attention more slowly — through the way light moves across its surface, through the depth of tone that emerges only after hours of finishing, through the particular quality of warmth it brings to a room that cooler, harder materials simply cannot replicate.
It is, in our view, the finest furniture timber grown on English soil. And it is, for reasons we will come to, increasingly rare.
This article is about English walnut specifically — its character, where it comes from, how we work with it, and what it asks of a maker in return. But it is also, in a broader sense, about the approach we bring to every material that comes into our studio. Walnut is the clearest expression of a set of values that run through everything we make.
What English walnut actually is
A clarification that matters: English walnut (Juglans regia) is not the same timber as American black walnut (Juglans nigra), which is more commonly seen in contemporary furniture and far more readily available on the commercial market.
American walnut is a fine wood. We are not dismissing it. But the two species are distinct in character, and the distinction is worth understanding if you are commissioning a piece or simply trying to make sense of why two walnut tables in two different showrooms look so different from one another.
English walnut tends toward a lighter, more varied palette — tones of grey, brown, and warm gold that shift considerably from heartwood to sapwood and from one tree to the next. Its grain is typically finer and more intricate, with a propensity for the figuring — feathering, curl, crotch — that makes individual slabs genuinely singular. Where American walnut is consistent and deep, English walnut is variable and luminous.
That variability is part of what makes it difficult to work with at scale, and part of what makes it so rewarding to work with at all.
Where it comes from
English walnut is not a plantation timber. It does not grow in managed commercial forests in the way that oak, ash, or American walnut does. It grows in parklands, estates, old orchards, and hedgerows — the remnant landscape of an England that managed its land differently, before agricultural intensification removed most of its field trees.
This matters for several reasons.
The first is availability. When an English walnut comes to market, it is almost always because a single tree has been felled — through age, storm damage, disease, or land management — rather than because a forest has been harvested. Each tree produces a finite and unrepeatable quantity of timber. The slabs cut from it will vary from one to the next in tone, figuring, and character. There will not be more where they came from, at least not for a generation.
The second is provenance. Because each piece of English walnut originates from a specific, identifiable tree in a specific location, it carries a story that commercial timber simply does not. The slab on our workshop floor came from an estate in the Weald. The tree stood for approximately 120 years. Its grain records that time in ways that are, when you look closely, genuinely readable — the wide rings of good growing years, the compressed rings of harder ones.
We source our English walnut from a small number of specialist UK sawmills and timber merchants who share our interest in provenance and who can tell us, when we ask, exactly where a board came from. This is not a marketing exercise. It is how we ensure that what we put into a commission is worthy of the commission.
The character of the wood
Every material has its own set of demands. English walnut's primary demand is patience — and then more patience.
It must be properly seasoned before it enters a workshop. Green timber — wood that retains significant moisture from the living tree — will move, crack, and warp after it has been worked. The rule of thumb for air drying is one year per inch of thickness. A two-inch slab takes two years to reach a stable moisture content. Kilning can accelerate this process, but not without cost to the timber's character: kiln-dried walnut lacks some of the depth that slow-dried wood develops.
We specify air-dried or air-and-kiln combined timber wherever possible, and we check moisture content before any piece enters a project. This is not unusual among serious makers. It is, however, frequently skipped among those for whom speed matters more than outcome.
Once on the bench, English walnut rewards careful attention at every stage. It machines cleanly but dulls tools faster than softer species. It responds well to hand planing — the surface quality achievable with a well-tuned hand plane is distinctly different from, and superior to, the surface left by a machine. The grain can be unpredictable around figuring: what planes cleanly in one direction will tear in another if you do not read it correctly before you begin.
None of this is a complaint. It is a description of what working with a material that has genuine character actually involves.
How we work with resin alongside it
English walnut and resin have a particular relationship that goes beyond aesthetics, though the aesthetics are considerable.
The warm tones of the walnut — those greys and golds and deep browns — sit in natural conversation with the colours available in resin: the glacial blues, the deep forest greens, the near-blacks that read as depth rather than absence of colour. Combinations that might look forced with a lighter or more uniform timber feel inevitable with walnut, because the wood itself already contains so much variation.
The technical challenge of the pairing is real. Wood and resin expand and contract at different rates in response to temperature and humidity. A join between them that is not properly engineered will eventually move — hairline cracks, slight lifting at the interface — in ways that are both visible and difficult to remedy after the fact.
We use specific epoxy formulations chosen for their flexibility and adhesion, and we design the wood-resin interface with movement in mind rather than in spite of it. Pieces that will live in centrally heated homes — which is most of them — are designed for that environment specifically. The same piece destined for a garden room or a conservatory is approached differently.
This level of consideration does not show up in a finished photograph. It shows up in how the piece looks five years after delivery, and ten years, and twenty.
The finishing process
Finishing is where the character of English walnut becomes fully visible, and where the difference between a well-made piece and an exceptional one is most clearly established.
We do not rush finishing. For a typical dining table surface, the finishing process runs to several days of work: initial sanding through progressive grits to remove any machine marks and level the surface; a grain-raising step with a water-based solution that reveals any remaining imperfections before the final surfaces are applied; further sanding to address those imperfections; and then the finish itself, applied in multiple coats with flattening between each.
The finish we specify varies by piece and by how it will be used. For surfaces that will see regular use — dining tables, desks — we use a hard-wearing oil-varnish blend that penetrates the timber and builds a protective layer above it. For display pieces and elements where the natural quality of the wood is the primary consideration, we use a pure oil finish that feeds the timber and leaves it with the closest possible approximation of its natural, unfurnished appearance.
In both cases, the final surface is hand-burnished. This last step — which takes time and produces no visible dramatic change — is what gives the finished piece its quality of depth. A surface that has been properly burnished looks different from one that has not. Not obviously different. But noticeably different to anyone paying attention.
Why material provenance matters to the people who commission us
We are sometimes asked, in early conversations with prospective clients, whether provenance really matters — whether a piece made from unnamed commercial walnut would look any different from one made from a traced, estate-grown English board.
The honest answer is: sometimes not immediately. To an untrained eye, in the wrong light, on a casual inspection, two pieces might appear broadly similar.
But that is not the right question. The right question is what you want to be true about the object you are commissioning. Do you want to know where the material came from? Do you want to be able to tell the story of the timber — the estate, the tree, the year it was felled — in the same way that you might tell the story of a wine or a piece of jewellery? Do you want the object to carry that specificity into the next generation, when you are no longer the one telling the story?
If the answer to any of those questions is yes, provenance matters. Not as a marketing claim. As a fact about what the piece actually is.
This is what we mean when we talk about objects of permanence. Permanence is not only about how long something lasts. It is about how much it carries.
Begin with a conversation
Every commission we take begins with a conversation about what the piece should be — and that conversation almost always includes a discussion of materials. Which timber. Which finish. How the resin and wood will meet. What the piece will look like in the room it is going into, and what it will look like in ten years.
If you are considering a commission — a dining table, a statement desk, a smaller piece built around a beautiful slab — we would welcome the opportunity to talk through what might be possible.
We take a limited number of commissions at any one time. Each one receives our complete attention from the first conversation to delivery.
