Demolition work has begun on Worthing's Teville Gate House as redevelopment of the site enters its next phase.
The vacant Railway Approach office block is the subject of a planning application, submitted in January, to be replaced by a five-storey building.
Renovating the 1970s property was not considered to be 'economically viable' and notice of the plans to demolish were approved in February.

Pictures from the scene show a large chunk of the block missing, with demolition equipment inside the shell of the walls.
The new five-storey office block will include secure parking for ten cars, including two accessible spaces, and secure storage for 70 bicycles.
A decision on the planning application is still pending.
