A rare opportunity to purchase a section of foreshore in the UK has been brought to the market.

The foreshore covers two parcels of land and stretches for some three miles along the Severn Estuary on the Welsh coastline, between Peterstone Wentlooge and the Rhymney River Estuary, near Rumney, on the outskirts of Cardiff.

Jay Ridsdale, a director in the Bristol office of Colliers International, which is managing the sale for the Joint Law of Property Act Receivers, Harry Dunger and Jon Cookson said: “It is very unusual for foreshore to be available for purchase in the UK, as the majority of it belongs to the Crown Estate.

“However, this section of land is freehold and is likely to attract interest from a range of purchasers.”

The sites total around 770 acres and adjoin the Wentlooge Levels Special Landscape Area and the Peterstone Marshes SSSI. The area is designated a Marine Special Landscape Area, and The Wales Coastal Path runs along the shoreline in front of the foreshore.

Jay Ridsdale said: “The land comprises an area of mudflats and salt marshes home to a range of species including wading and migratory birds.

“The land is understood to be within the proposed Cardiff Tidal Power Lagoon. It therefore expected that it will be of interest to purchasers, including amenity users, those with an environmental interest and investors.

Colliers International has instructed Newport-based Paul Fosh Auctions to conduct the sale, which has a guide price of £20,000 - £25,000 for the freehold of the foreshore, which is defined as the area between high and low water marks. The auction will take place on Thursday 24 March, at the Park Inn Hotel in Cardiff.
