About the event

Join us to visit this exciting project in the Chew Valley, near Bristol / Bath, where the existing listed stone barn is mid-conversion into a four-bed house.

Speakers Richard Hatfield - Construction Manager, and Henry Duncan - Project Designer, from sustainable design and build specialists Greenheart, will guide you around the site.  

Richard and Henry will outline different aspects of the build, including:  

• how it is designed to meet EnerPHit using component energy efficiency standards 
• listed building requirements to keep as many internal features as possible, such as exposed floor joists 
• The reasons various insulation types are being used; eg. floors using foam glass
• walls internally insulated with spray hemp and lime, and warmcell cellulose for the roof 
• ASHP, MVHR, and airtightness of better than 1.0 ach
• new triple glazed windows 
• new roofs throughout
• new kitchen extension 

See here for a walk around of the barn before any work was started. 

Light refreshments will be provided. 

About the Speakers

Richard Hatfield, MSc MRes - Construction Manager, Greenheart Construction 

Twenty years of Managing Greenheart Construction has given Richard a wealth of experience in the green building sector. Prior to that Richard’s background was in Carpentry, building his own timber framed house, civil engineering and environmental consultancy. He has a masters in Built environment research from Leeds University and has always been passionate advocate of being part of the solution to climate change.

Henry Duncan - Project Designer, Greenheart Construction 

Henry is a Carpenter turned designer, Passivhaus consultant and co-director of Greenheart. With a degree in 3D design from the University of Brighton, and a background in traditional oak framing, Henry approaches design challenges from a construction perspective. Aesthetics, form, texture, light and space are pillars of good architectural design, but worthless if the building can’t be built in a practical and cost-effective way and stand the test of time. 

Greenheart specialises in new build passivhaus using low carbon materials. They emphasise the importance of team work to ensure all parties from clients to labourers are fully on board with what they are trying to achieve, and the process is positive, inclusive and enjoyable for all.
