Overview

• Estate agent Strutt & Parker is inviting offers for the island, which is listed at around £3 million and has not yet attracted a buyer.
• Former software CEO Mike Conner purchased the derelict 19th-century fort for £555,000 in 2017 and spent five years transforming it into a self-sufficient estate.
• The 2.5-acre property now boasts more than 8,000 square feet of living space, featuring five bedrooms, a helipad and a private nightclub.
• Conner envisions the site serving as a retreat or venue for large events and estimates it could accommodate up to 800 guests without disturbing neighbors.
• Renovation work required complex logistics, including helicoptering in materials and a £200,000 biodigester installation that involved cutting through 16 feet of rock.
