Nigel Gervis is co-founder and Technical Director of Ty-Mawr Lime Ltd, a manufacturer and supplier of traditional and sustainable building materials based in Wales. His interest in traditional building materials developed whilst working as a builder in London and then Wales in the early 80s for a specialist building conservation company, Capps and Capps. He purchased Ty-Mawr, a former farm, with his wife in 1993 and began producing traditional lime based building materials to repair the property. They established the business on-site in 1995 and since that time Ty-Mawr Lime Ltd has seen enormous growth in the demand for their products and have now supplied over 26,000 conservation and ecological building projects right across the UK. Reintroducing skills has been of primary concern for the business, Nigel started organising and running courses in 1996 for homeowners, builders and professional specifiers. Tailor made courses and information days have been developed and run for a wide range of organisations including the Landmark Trust, British Waterways, the Canal’s Trust, Local Authorities and the Prince’s Foundation for Building Community. Nigel has given talks all over the UK on the specification, development and use of lime and regularly provides RIBA accredited CPDs to the country’s top architectural practices. Nigel was awarded the Marsh Award for training in Traditional Building Skills and has won several awards for his work in developing innovative products and systems such as sublime (insulated Limecrete floor) and glaster (lime plaster made with recycled glass). The business is proud to have achieved the British Standards Institute quality and environmental management system standards and very much practices what they preach by e.g. using their products throughout the restoration of Ty-Mawr, heating the site with a biomass boiler, using solar thermal for hot water for the training centre and more recently have purchased their first 100% electric car.
