University of Hertfordshire researchers and UK Hempcrete are developing a building coating that uses bacteria to protect and self-repair against erosion. An innovation for a pioneering new limewash for building surfaces, which uses bacteria to form a barrier against erosion damage, will be trialed by Whyte & Mackay at their Isle of Jura Distillery. The […]
A checklist of 10 essential building construction tips and how the ISOHemp™ block system available from UK Hempcrete and Natural Building Store ticks each of the boxes.
Tritton Road is a London based modestly sized rear single-storey extension, which has been carried to completion by the self-builder client to an impressive specification. Tritton Road is small but perfectly formed.
Illingworths Barn is an extensive renovation of a 18th century Yorkshire stone barn. Natural materials have been prioritised throughout the design of this project. The pine king-post roof trusses have been left exposed in the existing building, and a new Douglas fir in-the-round column and glulam beam structure is used in the new glazed extension.
What’s new in Hempcrete Blocks? It was really interesting to see IsoHemp’s new Hempro loadbearing system for hempcrete block walls under construction on site last month. The new system consists of normal hempcrete blocks that have been adapted to allow the casting of a reinforced concrete frame inside the hempcrete wall as the building goes […]
Show Season Ecobuild 2017 With a busier-than-ever year ahead of us, UK Hempcrete is currently in the thick of the show season. If you missed us at ASBP ‘Healthy Buildings’ conference, and Build It Live North West, catch us at Ecobuild (7-9 March). We’ll be casting hempcrete into a timber frame and showing our pre-cast […]
Free food, and accommodation in the beautiful French Alps in exchange for your work casting hempcrete in a new build Alpine chalet. Summer’s (nearly) here… and the hempcrete season has begun! We’re posting this for some clients of ours who are self-building a timber frame and hempcrete chalet near Chamonix in the French Alps. They […]
Part 2 of our blog post comparing natural and synthetic insulation materials… “We shape our buildings; thereafter they shape us…” Winston Churchill (1874-1965) In Part 1 of this blog article I looked at the problems inherent in trying to reduce carbon emissions in the built environment by using huge amounts of synthetic materials to insulate […]

We’ve put together a Hempcrete Information video playlist on our You Tube Channel to help share quality information about hempcrete, and we’re adding to it all the time. We’ll be flagging up key videos on the blog over the coming months Here’s a taster – HLC’s most recent video:
“We shape our buildings; thereafter they shape us…” said Winston Churchill (1874-1965), who died 50 years ago this this week. This oft-quoted comment on architecture resonates today as much it ever did. With the emphasis today on building (and upgrading our existing buildings) to meet standards of energy performance – in both construction and use […]
NATURAL BUILDING LIVE, NEC 9-12 October 2014 Hempcrete, along with other natural building materials, proved a major attraction at the Grand Designs Live Show at the NEC, Birmingham in October 2014. Hemp-LimeConstruct has been involved with the show for the last 4 years, helping to promote hempcrete by demonstrating it, along with other natural building […]
What can I expect from hempcrete in terms of its thermal performance? The thermal properties of hempcrete are extraordinary. It provides insulation because of pockets of air trapped within the material; both in the spaces between particles of hemp shiv, and in microscopic pores in the hemp shiv itself. Compared to synthetic insulation materials, hempcrete […]
Hempcrete is completely natural and free from synthetic, fossil fuel based materials. Because hempcrete is naturally fire-retardant and pest-resistant (nothing eats lime!) there is no need to add chemicals to ensure its performance in these areas (as is usually the case with lightweight synthetic insulation materials). Chemicals added to conventional insulation materials often contain Volatile […]
Hempcrete is carbon negative Hempcrete is a “carbon-negative” or ”better-than-zero-carbon” material; more carbon is taken out of the atmosphere by the growth of the hemp plant than is emitted as a result of its production and application on site. Various estimates for the amount of carbon sequestered have been put forward, and of course this […]
So what exactly can you can use hempcrete for? In new-build, hempcrete is most commonly used to make walls, but can also be used to form floor slabs, ceilings, and roof insulation. Hempcrete walls In contrast to conventional insulation materials (which tend to be installed in a cavity within the wall, or added to wall […]
I own this gorgeous grade II listed timber framed building that dates from the 13th Century. Last year, one of the corner posts disintegrated and during the repairs, we discovered that at some point in its recent past, the walls had been repaired using concrete, tar paper and various other non suitable materials. The result […]
This blog is taken from a talk given by our very own Will at the Grand Designs live in London 2012. Description Timber (elm) framed barn on a green sandstone rubble to the ground floor. About 50 years ago the wattle and daub had been replaced in the in-fill panels with cement render on a […]
