About Us

Who We Are

Thomas Macrae Ltd was established in 2010 and we, Dylan Thomas and Evan MacRae ( the directors), have over 50 years combined experience in the construction and carpentry trade. We have lived in the Teifi Valley area all of our lives and have a strong sense of community and knowledge of our local area and the people who live here.
We believe in building better, and giving an end product that will work for the client and the environment it’s in, and that will stand the test of time whilst improving the quality of life for the occupier.

We are vastly experienced in all types of construction and can advise on the one that will suit you best, be it Timber Frame, Traditional brick or the Insulated Concrete Formwork method. We are of the very few firms that are specialised in the I.C.F method and have built many projects using this innovative and superior system, including our own homes, so we know how well this works.

We are Timber Framing and Roofing Experts and Specialists in ICF (Insulated Concrete Formwork).
