This derelict office block is called Esplanade House and is located on the seafront on Eastern Esplanade, Southend. It is the former offices to the old gas works (stock photo left of the complete offices) and has been empty for over five years. Part of the building has been demolished and the site cleared for the construction of a large luxury hotel but work has not yet commenced and the building and surrounding area remain an eye-sore.
