In St Austell supermarket store wars are rife. In March 2013 Terrace Hill's application for an as yet unknown store on the site of the current Cornwall Council One Stop Shop, on Penwinnick Road, has the backing of council officers. It would see the existing council offices demolished and a supermarket built on the land, with new office accommodation built alongside.
A Cornwall Council planning officer's report states that Penwinnick Road is the preferred site for a supermarket as it is closer to the town centre, giving more opportunity for linked trips.
Broadley Park Properties has applied to build a Morrisons supermarket on land at Pentewan Road – but their application has been recommended for refusal by the council.
