Centre for Alternative Technology Demo Zone*

In addition to the seminars, workshops and one-to-one consultations with eco-experts, at Build It Live Bicester you can see live demonstrations from the Centre for Alternative Technology (CAT).

The Centre for Alternative Technology (CAT) is an educational visitors’ centre based in Central Wales. During the two day event the CAT mastercarpenter and course tutor, Carwyn Lloyd-Jones, will construct a timber-frame similar to the one pictured here in the Centre for Alternative Technology Demo Zone.

Carwyn will be building a section of a timber frame using the Walter Segal method: simple overlapping of timber using bolts to hold it together. It’s a straightforward technique to learn, making it ideal for first-time self builders.

This will involve:

  • Laying out the timber to show the position and get the overall shape
  • Marking out the joints and the position of the holes
  • Cutting the joints
  • Assembling the frame


CAT runs courses in self-build timber frame techniques and a wide range of other topics related to sustainable living, offering everything from day courses to postgraduate degrees.
