Preparation for the demolition of one of Camborne's most historic industrial buildings begins on Monday.
The old Holman's factory is on the site in Camborne
Hoardings that will surround the Comp-Air Holman site when the bulldozers move in are being put up and painted by local youth groups.
The bulk of the Comp-Air big shed has been derelict for two years after the firm closed its business in Cornwall.
It is going to be demolished to make way for a £90m development of homes and light industrial units.
New avenues will link the Dolcoath site with the centre of Camborne.
The site is now owned by national regeneration agency English Partnerships.
