A £100m plan has been unveiled to develop land adjacent to the Odyssey entertainment complex in Belfast.
Planning permission is being sought for 800 residential units, two hotels and a promenade.
The Odyssey Trust said the idea was to better integrate the site with the rest of the city centre.
The Trust has been working on its plan for two years and hopes to secure outline planning permission within 12 months.
Chief Executive Robert Fitzpatrick said: "While it would be easy to fear the impact of the current recession, we believe there is a bright future for the Odyssey and that now is the time to begin the work to secure and sustain its future success."
The project would be financed entirely by private investment.
"After much creative and innovative work, we have submitted a master plan that begins to articulate our vision for the future," said Mr Fitzpatrick.
Most of the project site takes in the complex's existing car park, though about 2,700 parking spaces are planned for a two-storey block integrated into the development.
On top of residential and hotel developments, the plan envisages a leisure facility, shops and a new civic plaza in front of the Odyssey.
The 10-year-old Odyssey complex was Northern Ireland's landmark millennium project, costing £120m.
Brian Hughes, the complex's operations director, said: "Instead of being relatively isolated and with a somewhat limited offer, the Odyssey of the future will be better accessed, multi-use, 24-hour environment."
