The sale of the 203‑acre former Shell oil depot in Rhosgoch on Wales’ largest island, marks a major moment for Anglesey, both in terms of scale and fiscal impact. This won it a CoStar Impact Award, as chosen by an independent panel of judges.
Originally a tank farm before the Amlwch terminal closed in 1990, the brownfield site now has changed hands for between £18 million and £18.5 million, a substantial increase from the £3 million Conygar Investment Company paid in 2015. The deal delivers an estimated £15.8 million profit for Conygar, which plans to use the proceeds to reduce debt and fund future development projects. The new owner is Stena Line via subsidiary Rhosgoch Property.
The size of the transaction highlights the growing strategic value of land on the island, particularly for sites with redevelopment potential. It also signals renewed investor confidence in Anglesey’s long‑term growth prospects.
About the project: For Stena Line, acquiring the site strengthens its expanding presence on the island and the alignment of its strategic interests with Anglesey Freeport. The company already has invested in land at Parc Cybi, just outside Holyhead and is behind a proposed marina development in the port town. This latest move is likely to support infrastructure and logistics and energy‑related opportunities, especially as wider discussions continue around projects such as the potential revival of nuclear development at Wylfa. The acquisition positions Stena Line as a key driver of future economic activity on Anglesey and adds further momentum to the island’s regeneration pipeline.
What the judges said: Kathryn Williams, managing director, KEW Planning, said, “this transaction unlocks numerous opportunities for North Wales in bringing forward new employment and energy projects". John James, director, Fletcher Morgan, said the “acquisition will transform a redundant site and have a significant impact on the local economy”, while Gary Carver, director, office agency, Savills, added it represented “confidence in Anglesey – and a very profitable transaction”.
Huw Thomas, director, Huw Thomas Commercial Property Consultancy, said this major investment across 200 acres bodes well for the freeport marina and the mooted development of nuclear facilities, both of which will result in a significant employment boost to the island of Anglesey and the wider region.
They made it happen: Freddie Jones, property director, Conygar.
