Frontier Oak has over a decade of experience specialising in bespoke handcrafted oak framed construction. We combine traditional craftsmanship and build methods, with contemporary design, to create a vast array of timeless oak framed buildings and extensions.

From the initial concept to the final build, and everything in between, we work closely with our clients to bring their ideas to life, offering a turnkey service. We fully project manage all areas of the build, from start to finish.

We operate throughout the South East of England, covering all areas of Sussex, Kent and Surrey.

Our Services

  • Extensions

    We build a lot of residential oak extensions, so we fully understand how to manage this process and limit the disruption caused when undertaking significant home improvements and building work.

    Building with oak can be a wonderfully interesting improvement to any home, as well as being a sustainable choice to typical building methods.

  • Garden Rooms

    An oak framed garden room combines timeless aesthetics with exceptional structural durability, creating a warm, natural focal point. A timber framed outbuilding offers superior flexibility in design, allowing for a comfortable, energy-efficient space tailored to work, relaxation or entertaining.

  • Orangeries

    An oak frame orangery is the perfect example of blending traditional craft with modern living: durable, thermally efficient, and timeless. Oak’s warmth creates a striking interior while large glazing boosts daylight, garden views, usable space and home value.

  • Conservatories

    Oak framed conservatories offer a much more usable and thermally efficient alternative to traditional victorian style glasshouses, as well as being a wonderful replacement for tired uPVC conservatories - most often we can do a direct replacement. The oak adds warmth and character, creating a light-filled, peaceful space that seamlessly connects indoors and outdoors.

  • Studios

    Oak framed studios provide durable, low-maintenance, well-insulated year-round spaces. Exposed oak adds traditional style and warmth; oak framing enables fast build times and strong thermal performance. They’re a great versatile choice for use as home offices or garden rooms.

  • Garages

    Oak framed garages offer classic character with the structural qualities of oak, providing a truly elegant storage solution. An oak framed garage adds kerb appeal to both period and modern homes. Traditional joinery and materials reduce repairs and lifetime maintenance, while bespoke sizing and detailing allow full customisation.

  • Outdoor Structures

    Oak frames are ideal for outdoor kitchens and similar structures: they are weather‑resistant, robust, and bring a lasting touch of handcrafted quality and character to any garden, enhancing both functionality and aesthetic appeal.

Our ethos

Our ethos is simple: a deep respect for timber, traditional craft and lasting quality. We have an ingrained passion for oak framed buildings - from cosy garden rooms to substantial home extensions, we bring a wealth of specialist experience to every project. We use time-honoured joinery techniques combined with careful modern detailing and design to ensure our builds are beautiful, robust and built to last.

Sustainability is integral to how we work. We prioritise environmentally responsible timber and partner only with suppliers whose materials meet PEFC standards. Our building methods aim to minimise waste and reduce environmental impact where possible.

Whether small or large, every build receives the same meticulous attention to detail and reverence for natural materials. The result: oak framed buildings that honour tradition, support sustainable forestry and stand the test of time.
