H.C.L Lime Workshops

Heritage Cob and Lime run practical and informative workshops designed to give beginners, keen DIY enthusiasts and experienced builders a hands on practical guide to working with lime mortar.

About the workshops

Our workshops have proved a very popular event since their inception back at the start of 2013. We currently put on a workshop event, usually on a Saturday (being self employed, we know how hard it is to take time out on a week day) roughly once every 2-3 months and places go fast, so if you're interested in joining us on a future course, call us right now to avoid disappointment.
