Gatwick airport has released this animation showing how it would phase up to £8.8bn of construction works.
An expansion of the Sussex airport is one of three options being considered by the Airports Commission to solve air capacity issues in the South East.
Gatwick insists a new runway and terminal could be operational by 2025, building on safeguarded land with private cash.
Subject to achieving necessary planning approvals by 2020, Gatwick would look to carry out expansion over the following 20 years.
The runway would cost £7.8bn including land purchase and associated works. A seperate £1bn programme of works is ongoing, mainly relating to the north terminal.
By the end of phase 1, in 2025, a new terminal would be operational at the same time as a new runway.
Phase 2, from 2025 to 2030, would consist of extending the second runway terminal to the north, and extending the contact pier and the first section of the remote pier.
Over the next five years, phase 3 would see a further extension to the new terminal and further extension of the remote pier.
Phase 4, to 2040, would consist of completing the new terminal and the remote pier. This would complete the scheme.
Gatwick Airport has appointed a new director of development as it steps up its bid to build an extra runway.
