Green Oak Timber Framing: Building Structures That Last 300 Years with Frontier Oak

Robin Johnson sits down with Christopher Kentish and Oliver Reimann, the co-founders of Frontier Oak, a bespoke green oak timber framing company based in Sussex. Chris came to the craft after a career in film production, introduced to it through his father-in-law's green oak company. Ollie, who studied advertising and marketing and met Chris at the age of 13, joined him in 2018 after working in production and photography. Together they have built Frontier Oak from the ground up, taking on everything from residential extensions, orangeries, and garden rooms to three-bay garages and contemporary pottery studios. Their ethos is straightforward: 100% bespoke, fully handcrafted, and managed end-to-end from groundworks to final finish. In this episode they talk honestly about what it takes to run a small craft business, why they refuse CNC machines, how they handle green oak's unique challenges, what the future of timber framing looks like, and why they are planning to take on apprentices to keep the craft alive.Key Topics CoveredWhat green oak timber framing actually involves and why it has been done the same way for hundreds of yearsHow Chris and Ollie each found their way into the trade from completely unrelated careersThe bread and butter of Frontier Oak's work: residential extensions, orangeries, garden rooms and standalone buildingsWhy green oak clients are a different type of customer and what drives them to choose timber over brick and mortarThe environmental case for green oak construction and the barriers to using fully sustainable building materialsThe technical challenge of working with green oak: movement, tolerances, pre-fitting frames and getting them to site fastHow CAD design fits into a traditional craft workflow without compromising the handmade approachPlans for oak framing workshops and apprenticeships, and the responsibility of passing the craft to the next generationThe unwritten rules around apprentices in traditional trades like thatching and farrieryEnjoying the show?Leave a review, follow us, and share the episode with a fellow maker.
