Nansledan has been developed by the estate of the Duchy of Cornwall since 2013, with residents first occupying their homes in 2015.

The development, officially described as 'an extension of Newquay', had the endorsement of King Charles III during his time as Duke of Cornwall.

The project was started in 2013 and initially attracted the nickname Surfbury, a mix of Poundbury, created by the Duchy of Cornwall in the 1990s, and the fact that Newquay is regarded as the British 'capital' of surfing.

In February 2024, Prince William, Duke of Cornwall, in partnership with Cornish charity St Petrocs, announced plans for building 24 homes on Duchy of Cornwall land in Nansledan to provide temporary accommodation for people experiencing homelessness in the area.
