Architect Make is developing plans to expand Stansted airport to up to four runways to solve the UK’s airport capacity problem

Make's design for four runways at Stansted airport

The move follows rival architect Foster + Partners’ plan for a hub airport in the Thames Estuary; Gatwick airport’s announcement that it will look to plan a second runway, and Heathrow’s continued lobbying for a third runway at its site.

Make believes Stansted could carry up to 150 million passengers a year under its plans. Plus, it said Heathrow would not have to close, which may be necessary under the Thames Estuary airport option.
