About us

Our Objectives

The Tywi Centre objectives are to ensure everyone who is responsible for looking after, or working on an old building has the right information, skills and materials for carrying out sensitive and appropriate repairs.  This will ensure that the our old buildings, both listed and non- listed, are around for a further 100 years and more. 

The site

The Tywi Centre is based at Dinefwr Farm, Llandeilo.  It is a Grade II listed group of barns, originally the Home Farm of the Newton House Estate, which is now run by the National Trust.  We have classroom facilities and can accommodate up to 20 people on a course or at a meeting, and an area for displays about old buildings.  We also have a series of specialist skills training facilities: a Plastering workshop where students can learn about plastering onto laths and creating running moulds; an outdoor shelter to practice external rendering techniques; a Carpentry workshop, large enough to accommodate both sash window work and timber frame repairs; and space to deliver stonemasonry training.

The services

We work with owners of old listed and non-listed buildings, with heritage and non-heritage contractors, with colleges and local charities – in fact anyone who wants to look after old buildings.  We can deliver one-to-one ‘surgeries’; training in maintenance and repair; specific craft skills training; guidance leaflets; and endless encouragement and support.


The Team

Nell Hellier

I am the Senior Built Heritage Officer at Carmarthenshire County Council and have been working in traditional building conservation at the Tywi Centre since 2008.  I live in an old building and so am familiar with all the challenges that come with it!  I am responsible for managing the Built Heritage Services of the county and delivering all the Tywi Centre projects, so if you need any training or general information about old buildings please contact me.  If I can’t help you I will always be happy to point you towards someone who can.  I am also involved in working across Wales to promote the heritage building agenda with the Welsh Traditional Buildings Forum and Cadw, amongst others.
