Rooted in Place. Skilled by Hand. Built for the Future.
The Tywi Centre exists to protect and pass on the skills that keep historic buildings alive.
Traditional buildings shape the character of our cities, towns and villages. They embody local materials, skilled hands and generations of knowledge. When the skills to repair them properly are lost, the buildings — and the communities around them — suffer.
We are here to safeguard those skills and raise standards across the sector.
Heritage Skills, Properly Taught
We deliver high‑quality training in traditional and heritage construction, with accredited pathways up to NVQ Level 3.
Our focus includes:
- Heritage carpentry and joinery
- Masonry and stone repair
- Lime work and traditional materials
- Conservation principles and repair philosophy
Training is practical, rigorous and grounded in real buildings.
All accredited programmes follow CITB standards and are regularly monitored to ensure quality and consistency. Learners leave not only qualified, but capable — with the judgement and professionalism required to work responsibly on historic fabric.
Learning Built Around People
We teach with clarity and purpose, valuing:
- Accuracy over speed
- Understanding over box‑ticking
- Skilled judgement over shortcuts
- Confidence built through real competence
We create an inclusive learning environment that supports a wide range of learning styles, experiences and strengths.
Assessment is designed to be fair, transparent and meaningful — a way of recognising genuine skill, progress and professional readiness.
Repair, Reuse and Retrofit — Done Properly
Historic buildings need informed care, not inappropriate modern interventions.
Traditional materials such as timber, stone and lime allow buildings to manage moisture and movement naturally. Incompatible products can cause lasting damage.
We promote approaches that are:
- Fabric‑first and evidence‑led
- Based on compatible, breathable materials
- Reversible wherever possible
- Proportionate to the building’s age and significance
Low‑carbon outcomes begin with repair, reuse and skilled decision‑making
Our Site
The Tywi Centre is based at Dinefwr Farm, Llandeilo, within a Grade II listed group of barns that once formed the Home Farm of the Newton House Estate, now managed by the National Trust.
Our facilities include a well‑equipped classroom for up to 20 participants, flexible training space and displays celebrating traditional building craft. The historic setting reinforces our purpose: the buildings themselves are part of the learning.
Our Work and Impact
We are the UK’s only provider of NVQ Level 3 qualifications in Heritage Carpentry, Heritage Masonry and Heritage Plastering.
Alongside our NVQs, we deliver accredited professional courses in energy efficiency for older buildings, best practice repair and maintenance, and traditional building performance.
We also:
- Provide bespoke heritage training for organisations
- Develop curriculum with qualification bodies
- Deliver grant‑funded projects benefiting communities
- Organise sector conferences and knowledge‑sharing events
- Offer one‑to‑one advice sessions and specialist guidance
Our work strengthens skills, raises standards and supports the long‑term future of historic buildings across Wales and the UK.
Why It Matters
The construction industry faces skills shortages while climate pressures demand sustainable solutions.
Repairing and adapting existing buildings is one of the most responsible choices we can make. That requires skill, knowledge and proper training.
The Tywi Centre invests in people so that traditional buildings — and the expertise to care for them — have a future.
