JUNO secured Listed Building Consent for upgrade works to three historically signficant lighthouses on Rathlin Island (Rathlin East, Rathlin West, and Rue Point). JUNO worked with heritage expert Dr Fred Hammond and conservation architects D-on Architects on the sensitive upgrade works, which would improve energy efficiency and the environmental footprint at these important heritage sites, as well as ensuring the lighthouses meet international standards as working Aids to Navigation used by every-day mariners.
