Vanguard Real Estate has submitted plans for the first phase of the £400m Belfast Waterside development.
Detailed plans for a 250,000 sq ft grade A office building have been submitted for the site of the former Sirocco Works.
Vanguard, the development arm behind Swinford (Sirocco) will make an initial £50m investment in the scheme.
Designed by Danish architect and master-planner Henning Larsen, Belfast Waterside will encompass a mix of corporate office occupiers and city residents alongside a range of media, performance and digital activities.
Jim Osborne, director, Vanguard Real Estate, said: “We are seeking to set a new benchmark for office space suitable for premium corporate occupiers.
“Recent reporting has indicated that Northern Ireland continues to attract foreign direct investment occupiers but an ongoing lack of quality supply is holding back office rental growth.
“Recent analysis from CBRE outlines that grade A office space remains in high demand from foreign direct investment and local companies.”
The office proposals have been submitted as phase one of wider plans to redevelop the largest brownfield city centre site in Belfast into a riverfront destination.
The mixed-use regeneration scheme will total 1.7m sq ft of development including offices, a hotel, serviced apartments, residential units for sale and rent, affordable, social housing and significant retail and leisure space.
The residential and co-working elements of the scheme will be brought forward in the coming months, together with proposals for a new pedestrian and cycle bridge.
Vanguard is formed of Gulf Resources Development & Investment (GRDI), Graftongate Developments, and The Corbally Group.
