Forestry & Provenance

Timber Sourcing & Sustainability

Responsibly harvested British hardwoods, FSC® chain of custody, and an uncompromising zero-waste workshop policy.

FSC® Chain of Custody

Living Materials with Documented Provenance

Every bespoke joinery piece we create begins in a managed, sustainable forest. Cotswold Woodcraft & Joinery Ltd holds chain of custody accreditation under FSC® FSC-C138942 and source partners verified by the Programme for the Endorsement of Forest Certification (PEFC).

We prioritize native British hardwoods harvested from certified woodlands in Gloucestershire, Herefordshire, and Oxfordshire. Sourcing locally minimizes transportation carbon emissions while supporting the active management of British deciduous woodlands—a critical factor in maintaining biodiversity and rural forestry economies.

Furthermore, solid timber is one of the world's most effective natural carbon sinks. The atmospheric carbon absorbed by a mature English oak remains safely sequestered within your fitted library or dining table for decades or centuries.

Our Material Palette

Hardwood Species We Craft

Prime English Oak

Quercus robur / Quercus petraea

The backbone of British architectural joinery. Revered for its golden amber hues, high tannin content providing natural rot resistance, and striking medullary ray flecks visible in quartersawn cuts. Ideal for heavy architectural libraries, entry doors, and structural timber frames.

Density: 720 kg/m³ | Hardness: Janka 1,120 lbf

British Olive Ash

Fraxinus excelsior

Renowned for its remarkable flexural strength, elasticity, and pale cream tone contrasted with dramatic dark brown 'olive' heartwood streaks. A magnificent tactile timber for bespoke dining tables, contemporary cabinetry, and fluted acoustic wall battens.

Density: 680 kg/m³ | Hardness: Janka 1,320 lbf

European Walnut

Juglans regia

The pinnacle of luxury cabinetmaking. Rich chocolate, mocha, and subtle violet undertones with complex swirling chatoyance. Moderately dense, exceptionally stable, and silky to the touch when finished with natural oils. Favoured for executive desks and cutlery inserts.

Density: 640 kg/m³ | Hardness: Janka 1,010 lbf

Sweet Chestnut

Castanea sativa

Historically coppiced across southern England. Visually resembling oak but slightly lighter in weight and free of pronounced medullary rays. Naturally resistant to insect attack and moisture, making it an outstanding sustainable option for external joinery and gates.

Density: 560 kg/m³ | Hardness: Janka 680 lbf

Accoya® Modified Timber

Acetylated Radiata Pine

A breakthrough in sustainable exterior timber technology. Non-toxic acetylation permanently alters wood cells so they cannot absorb water. Virtually zero shrinkage, swelling, or rotting. Guaranteed for 50 years above ground, perfect for conservation box sash windows.

Density: 510 kg/m³ | Durability: Class 1 (50-Yr Life)

English Elm

Ulmus procera (Reclaimed/Estate Fallen)

Celebrated for its wild interlocking grain, rugged natural edges, and rich reddish-brown patina. Because native elm is rare due to historic Dutch Elm disease, we source exclusively from storm-felled estate specimens for one-of-a-kind statement conference and dining tables.

Density: 580 kg/m³ | Grain: Interlocked Wild Patina
Circular Workshop Operation

Zero-Waste Commitment in Minster Lovell

Our Oxfordshire workshop generates zero wood-waste sent to municipal landfills. Large offcuts are transformed into handcrafted wooden boxes, chopping boards, or test sample blocks for architects. Intermediate offcuts fuel our biomass timber drying kiln, providing clean workshop heating through the winter months.

Clean, untreated hardwood sawdust and shavings are collected and delivered weekly to certified organic agricultural composters and local equestrian stables in West Oxfordshire.

100% Repurposed
Every cubic foot of timber utilised cleanly.
