A timber frame specialist is a craftsperson with expertise in the repair, restoration and construction of traditional timber-framed buildings using oak and other hardwoods. Unlike modern softwood stud framing, traditional timber frames use mortice and tenon joints secured with hardwood pegs - a system that has been used in the UK for over 800 years. These specialists are essential for the repair of listed buildings and historic structures where appropriate materials and methods must be used to comply with Listed Building Consent conditions and the guidance of Historic England and SPAB.
What they do
- Inspect and assess structural condition of traditional timber frames
- Repair and splice deteriorated timbers using traditional scarfing joints
- Replace principal rafters, wall plates and structural members
- Repair jettied upper floors and overhanging structural elements
- Reinstate wattle and daub or other traditional infill panels
- Construct new oak frame buildings using traditional joinery
- Carry out structural timber surveys and produce reports
- Produce heritage documentation for listed building applications
- Advise on appropriate treatments for preserving historic oak
When you need one
A timber frame specialist is needed whenever traditional hardwood frame buildings require assessment, repair or restoration - and for new oak frame construction.

What is the difference between softwood and oak frame construction?
Oak and other hardwood frames are the traditional British approach - the frame carries all structural loads and the infill panels are non-structural. Softwood stud frames are more common in modern construction but lack the longevity and character of hardwood frames. Traditional oak frames are built using mortice and tenon joints secured with hardwood pegs, without nails or metal connectors.
Can a modern house be built with traditional timber framing?
Yes - traditional oak frame buildings are increasingly popular for self-builders. The frame can be paired with modern insulated panels (SIPs) for energy efficiency while maintaining traditional joinery techniques. Building Regulations approval is required and a structural engineer with experience of timber frame construction should be involved.
Does a timber frame survey require a specialist?
Yes - identifying and assessing structural defects in traditional timber frames requires expertise in historic construction. Deterioration in oak frame buildings is often concealed by later plaster, render or cladding. A timber frame specialist or structural engineer with experience of historic buildings should carry out the survey to identify rot, insect attack, joint failure and movement.
