In June, the National Infrastructure Commission (NIC) launched the competition seeking "visionary ideas for development typologies across the Cambridge - Milton Keynes - Oxford corridor".
In August, the NIC announced that four teams led by consultancy Barton Willmore, Fletcher Priest Architects, Mae Architects and consultancy Tibbalds Planning and Urban Design had been shortlisted.
Now, the NIC has revealed the teams’ final design concepts.
The proposals for enhancing the corridor include a new National Park; an "a constellation of linked, distinctive and compact places set within a continuous landscape"; an "ecologically rich urban settlement for the Just About Managing"; and a reimagining of the "21st-century village".
The full design concepts can be viewed here.
Competition organiser Malcolm Reading, said: "These are four very diverse proposals that propel us deep into the 21st century. They show that it is possible to be imaginative in responding to a raft of competing challenges and are an urgent reminder that we do need a plan and a strategy or we will be overtaken by the times – losing out economically, in terms of quality of life, or both.
"We’re delighted that this ideas competition has generated a new set of possibilities that contribute to the wider debate of how we, as a nation, want to ‘design’ our future."
The NIC said that it will announce the overall winning entry for the competition in November and publish its final report and recommendations for further supporting the growth corridor.
