We pride ourselves on our knowledge of lime and the materials we sell and are always available to offer advice and support.

We offer a consultancy service, we can carry out a site visit to assess your building and offer practical and genuine advice.

We run courses through the warmer months to equip you with the expertise to work with lime, learn traditional building crafts or just enjoy picking up a new skill and visiting us here at Plas Tirion, our own ongoing 16th Century restoration project.

“I want to thank you for a fantastic course. Ned and Hefin were wonderful. What an amazing day!”   Pete 2015

“We really enjoyed and valued the site visit; we couldn’t have wished for more. It was a genuine and personable consultation, the comprehensive knowledge and expertise around old buildings, products and restoration products was evident. Action was planned with a sensitivity to our aesthetic preferences and available budget. We thoroughly recommend consulting the Natural Building Centre”  Gareth, Caernarvon 2015
