GPJ Consulting Engineers were employed to design the Mechanical and Electrical services for this new community hall on the remote island of St Agnes located 29 miles off the Cornish mainland.

The new hall building was to be a timber framed extension off the existing hall building.  The building was designed to be a multipurpose facility for the local community.  It comprised a main meeting room, 6 workspace units, storage areas, kitchen and plant room.

The building was heated by ground source heat pumps providing underfloor heating throughout.  Wastewater was treated on site with a packaged digester with the clean outfall discharged to sea.  Rainwater is collected and utilised for toilet flushing.  Photovoltaic panels generate approximately 10KW of electricity to reduce the grid loading.

The building was awarded a BREEAM excellent rating and was recipient of a Sustainable Cornwall Award in the Sustainable Built Environment category in 2014 and was nominated for ‘Eco Project of the Year’ in the Michelmores South West Property Awards.
