We specialise in the design, construction and erection of traditionally jointed and pegged bespoke timber framed buildings and green oak structures.

Our Oak Sawmill We use locally grown English timber which we carefully select, grade and saw on our own sawmill in Devon.

Our timber frames are all made in our workshop and framing yard near Tavistock in Devon using locally grown English Oak, Douglas Fir or Larch. Each of our frames is individually designed and absolutely unique. We can make different styles of timber frame, from very contemporary frames with straight cut timber, to traditional medieval style green oak 'cruck' frames where the two paired halves of a curved oak tree are used. Our timber framers use traditional carpentry techniques and we take pride in producing beautiful, durable, energy efficient buildings using locally sourced renewable materials.

Design Service: We work closely with an architectural designer and we can provide a full design and drawing service for your timber framed buiding project. Alternatively we are happy to work with your own architect or frame designer.

Glazing Green Oak: Green oak requires the application of specialist glazing techniques and we can offer a glazing service for our timber frames.

The small gazebo shown on the right is built by the traditional scribe framing method of marking and cutting timber. This method allows for the accurate jointing of hand hewn or crooked timbers. Our timber frames can therefore be made using either straight cut timbers or rustic looking bent or 'wainy' edged timbers.

Traditional Green Oak Heavy Structural Timber Framing

Our lead timber framer is Nigel Harrison."I have been involved in many unusual carpentry projects over the years, and I became interested in building green oak timber framed structures when my imagination was caught by the strength, beauty, and extraordinary durability of English Oak timber framed buildings. I am passionate about preserving traditional carpentry techniques and using them to construct new, durable, energy efficient buildings, using local sustainably produced, renewable materials".

Traditional Timber Framing: Materials and Methods.

When making our timber frames, we remain as true as possible to traditional jointed and pegged timber framing methods. The oak pegs can be cut flush but many of our customers prefer some to be left raised as a feature as shown in the view from inside a section of a glazed garden room, shown below.

Locally grown English Oak on our sawmill in Devon

We are committed to supporting our forestry industry which in turn will encourage local managed production of timber as a source of both renewable fuel and sustainable carbon neutral building material. We have our own sawmill and we buy good quality local timber in the round which we grade and saw ourselves. This allows us to control timber quality and ensure a supply of naturally curved timber for use in curved braces and tie beams.

Frame Drawing, Design and Planning

We will construct timber frames from your own architects design or we can provide a full design and CAD drawing service for your timber framed building project. We work with an architectural designer who will prepare drawings for planning approval and building regulations purposes.

In addition, we have specialist timber framing software which allows us to create our own 3D CAD detailed workshop frame drawings (as shown above and below) for our carpenters to work from and which we use when it is necessary to instruct a structural engineer. These drawings can also be used to show our customers a 3D image of their building project.

Green Oak Trusses

Green Oak trusses can add character to buildings and can be made in many different styles. Shown below is a house extension with King Post trusses made from English Green Oak with curved struts. (The hand made kitchen was made by Pete White at www.TamarValleyWoodworks.co.uk)

The photo below shows a section of some English green oak trusses to be used in the restoration of a barn at Brimpts Farm on Dartmoor.

Glazing Green Oak Timber Frames

Glazing green oak requires specialist techniques to overcome problems which could be caused by movement of the timber. The demands of building controls as well as a basic need for good energy efficiency means that efficient glazing is an essential part of modern timber framing. We offer a glazing service for our own oak timber frames. In the photo on the right, Nigel is shown finishing the external glazing panels on one of our green oak frames
