Its been four years since plans were passed for Bovis Homes to build 385 houses on the former mill site in Factory Lane, and almost two years since the Sumpter Horse pub in Leyland Road was shut to make way for an access road.
The Sumpter Horse pub is still standing, and there has been no explanation of why a new developer has taken over the site.
Bovis Homes has declined to comment on the situation and there is no information on whether Bovis promise of investment in the nearby Vernon Carus Sports Club will be upheld.
Lane End Developments Ltd have carried out a substantial amount of work with social landlords, but there is no information on whether the Penwortham development will be in conjunction with a social landlord.
Penwortham Mill was built in the lates 1700s by John Watson as a textile factory which included weaving and fabric production.
