Green Dragons Den - Results

Date : 2012-10-02


The final of the Build Norfolk and BEST East Green Dragon’s Den competition to find people with new and bright innovative ideas, services, products, concepts or materials for sustainable construction took place at the Pennoyer Centre, Pulham St Mary on the 28th September

and what a great day it was!


The finalists had been narrowed down to just 7 superb entries:

A company that retrofits and maintains high buildings using professional abseilers to save the cost, danger and carbon impact of scaffolding.

A system of producing roof thatch and wall insulating thatch panels off-site using locally-grown straw and reed

A company that builds new structures up to 3 stories using locally-grown hemp aggregate and unique Hempcrete spray equipment to create multiple design options

A complete low-cost building system to Passiv Haus standards than can be undertaken using semi-skilled workers

A design for a machine for safely recycling and reusing asbestos reclaimed from old buildings

An aerofoil-inspired roof system to support sedum and other plant roofs on small buildings (right down to dog kennels!) providing new design options

Offsite produced roof and floor cassette systems that considerably speed up the building process


In true Dragon’s Den style, each finalist was rigorously “grilled” by our Dragons

Every entry was commended by the Dragon’s but at the end of the day there could only be one winner

the Ashby St Mary-based

Limecrete Company


...... for their innovative techniques and equipment for spray-applying Hempcrete – one of the most sustainable construction materials available – and a material that incorporates hemp commercially grown throughout the East Anglian region.

Media coverage of the event has included BBC Radio Norfolk (twice) and the Eastern Daily Press so we’re confident that interest in local sustainable construction innovation remains high. If you’d like to find out more about our final entries, you can download their presentations here:
