The Duporth Ward is based around a beautiful bay comprising two privately owned sections of beach. The larger area from the eastern end of the beach almost up to the large concrete steps is owned by a limited company whose shareholders are the residents of the Duporth Bay estate. The remainder of the beach is owned by the residents of the new estates, An Arvor and Two Coves, which are still under construction.Prior to 2005, Duporth consisted only of the Duporth Bay private estate and a neighbouring holiday park composed of more than 250 caravans and holiday chalets. This was sold in 2006 and planning permission granted for over 300 homes. Building is well advanced and the new estate provides a very attractive mix of properties, from single bed flats to 5 bedroom, three-storey landmark houses. The extensive woodland area to the east of the new development forms a natural boundary between Duporth and Porthpean, another Ward of the St Austell Bay Parish. Because of the anomaly in the drawing up of ward boundaries a small area of Porthpean, Ridgewood Close, is actually included in the Duporth Ward, although residents naturally gravitate to their geographical neighbours.
Duporth Road, often called Brick Hill, is a very attractive, narrow, tree-lined road linking the three Wards of Charlestown, Duporth and Porthpean, which, together with Trenarren make up the St Austell Bay Parish.
