London Southend Airport has announced that work is about to begin to extend the terminal building.
The first phase is a new arrivals facility which is due to be ready at the end of May 2013. The final phase will be completed just before Christmas 2013.
The extension will cost around £10 million to complete and will result in the existing terminal becoming 90 metres longer.
The number of check in desks and baggage drop off points will also increase, as will the amount of space for passengers in security.
The Departure Lounge will grow in size and there will be a larger arrivals area. Retail and catering facilities are also being expanded.
Airport managers say they hope the new expansion will lead to 300 new jobs being created.
London Southend Airport is owned by the Stobart Group which acquired it in 2008.
