Who we are

Designers, specifiers, consultants, trainers, construction products suppliers...

UK Hempcrete is a market leading company, specialising in the use of Hempcrete (or ‘hemp-lime’) and other biobased materials in construction. Collectively our highly specialist team has decades of experience of using these low- or zero-carbon construction products in both new build and retrofit; especially in the upgrading and repair of traditional and historic buildings.

Our CEO, Alex Sparrow, is recognised globally as a leading consultant in the use of Hempcrete: regularly speaking at conferences and events, writing articles and hosting training days. Alex co-wrote The Hempcrete Book: Designing and building with hemp-lime, (2014 UIT/Green Books, Cambridge) which has been widely acknowledged as the definitive guide to the use of cast-on-site Hempcrete in construction. Alex sits on the board of the Alliance for Sustainable Building Products (ASBP) and YorSpace Community Land Trust in York, and speaks internationally, as well as providing training and consultancy services with a global reach to assist others in the use of hempcrete and bio-based construction materials.
