Mind that it isn't a "complete" airport. It's on the area of Berlin-Schönefeld airport. Thus less need to acquire new land. Which I expect to be a notable part for a new runway in London's vicinity (of course a new runway also requires new fire fighting station and new tower etc. to guarantee service, such a project is a bit more than just the runway)
