LDA Design has submitted a planning application for its new urban park on Blackpool's promenade, dubbed the 'People's Playground'.
The Exeter-based practice bagged the chance to landscape 10.5ha of Blackpool's seafront after winning an international design competition worth £21 million.
The proposals were submitted to the council by Blackpool's regeneration body ReBlackpool on Monday and, if given the green light, will create a 'spectacular night-time landscape', illuminated by the Northern Lights.
It is hoped the development will turn this part of Blackpool's coastline into a '21st-century leisure resort', providing people with public arts and performance space, a visitor education centre and a café and restaurant.
Should the plans be rubber-stamped by Blackpool City Council, the scheme will still be subject to funding approval by the North West Development Agency and the Big Lottery Fund.
LDA associate director Robert Aspland said: 'The People's Playground called for something that would excite and amaze residents and visitors alike, while creating a place for escape and fantasy.
'We look forward to achieving planning consent for the scheme and making this come true for residents and visitors alike.'by Richard Vaughan
