Saturday 1 – Sunday 2 June 2024
This two-day course runs from 9.00am to 5.30pm in Stanmer Park, Brighton.
The course provides an introduction to the theory and practice of building with hemp lime, also known as hempcrete, including how to use it in the repair and upgrading of old buildings.
Who is the Building with hemp lime course for?
This course is open to anyone aged 16 or over. It is suitable for anyone interested in learning about hempcrete construction, whether they are planning their own project as a self-builder, architect or contractor, or just wanting to gain practical experience of the different ways of using this material. No prior knowledge is assumed, so the course is suitable for complete beginners as well as those with some building experience.

Learning methods and outcomes
The course is spread over two days with a mixture of practical and theory sessions, reflecting the fact that, to use hempcrete successfully, builders need to have a proper understanding of the materials as well as good practical skills. There will be time for questions at the end of the day, but they are always welcome as we go along. All equipment is provided for practical sessions.
By the end of the course, participants will:
- have learnt a little about the hempcrete building industry in the UK today
- have a basic understanding of the key theoretical and practical issues to consider when building with hempcrete, in both new-build and restoration.
- know the issues involved when choosing a hempcrete binder
- have a good understanding of the basic method of hempcrete building, including the important dos and don’ts
- have gained practical experience of:
- building a section of new build hempcrete wall
- applying finishes to hempcrete
- insulating with hempcrete in a historic/traditional building context
The course will be led by Alex Sparrow, co-director of UK Hempcrete, a UK company specialising in the use of hempcrete alongside other natural building materials. Alex has been building with hempcrete since 2008 and provides consultancy and training to other builders, home owners and architects, as well as regularly speaking about the material at public events and writing on the subject. Alex is a co-author of the definitive guide to using this innovative, better-than-zero-carbon building material, The Hempcrete Book: Designing and building with hemp-lime (October 2014).
