Make plans to submit its work to the Airports Commission in July, setting out the feasibility of expanding Stansted to become an international hub airport.
Make says that its proposals would cost £18bn to deliver and would provide up to £100bn in investment for the east of the country.
Ken Shuttleworth, founder of Make, said: "Everyone now recognises the need for new airport capacity in order to maintain the UK’s position in the global economy. The question remains as to where. The location should be such that it can serve the whole country efficiently for the next century. We have proved that Stansted is a viable option, deliverable, affordable and linking to central London in less than 30 minutes, crucially ensuring the distribution of growth and economic development to benefit the national population."
Stuart Blower, partner at Make said: "The main benefits of upgrading Stansted is that there is no requirement for planes to fly over London which minimises the number of people affected whilst still ensuring the growth in capacity. By building on existing facilities and infrastructure, construction and development can be phased if necessary, up-front costs can be reduced and the benefits of existing assets can be maximised through improved surface public transport connections."
Make’s strategy will act as a catalyst for the Lea Valley and the Eastern Regions, building on the growing technology and R&D corridor that is developing between the east of London and Cambridge and facilitating a new centre of gravity that allows the eastern towns and cities to prosper in the same manner that Heathrow has done for the Thames Valley.
Improvements are proposed for the West Anglia Main Line and a new Stansted Express would link the airport with London’s Liverpool Street station in 25 minutes. Other options studied include extending Crossrail 1 and Crossrail 2 to link Stansted with a number of central London locations in 30 minutes; refurbishing and extending the Varsity Line to Cambridge, Oxford and beyond; and a potential third High Speed rail line (HS3) connecting to St Pancras in central London.
