Construction company Bouygues UK has been unveiled as the main contractor for a new high-tech office in The Kingsway.
Swansea Council said work on the five-storey building where the Oceana nightclub once stood would get underway this summer and finish next year.
The £33 million building will provide space for 600 jobs and is aimed at tech, digital and creative businesses. Known as 71/72 The Kingsway, it will link through to Oxford Street and feature top-class digital connectivity, a roof terrace, greenery and balconies overlooking the city centre.
Bouygues UK is also constructing an innovation campus at Cardiff University and Bristol's tallest residential building, among other projects.
Swansea Council leader Rob Stewart said he was delighted to announce the company as the main contractor. The city, he said, had significant un-met demand for quality office space resulting in some companies leaving the area.
"Despite a recent trend of more people working from home, interest in this development is still considerable," said Cllr Stewart.
"Positive discussions with a potential building operator and tenants are advanced, with a recent review showing the development’s design to be Covid-resilient."
The Swansea Labour leader said local businesses would benefit from work, training and supply chain opportunities.
Mike Baynham, Bouygues UK operations director for Wales, said the building would transform the surrounding area.
He said: "The Kingsway has already seen a huge amount of improvements in recent years and this contemporary, flexible office development with opportunities for retail and leisure will further add to the regeneration of Swansea and the Swansea Bay City Region as a whole."

The council will fund the office and claw back some costs via the city deal for the region. A European Union contribution, via the Welsh Government, has also been secured. Cabinet committed to developing 71/72 The Kingsway at a behind-closed-doors meeting in May. A cross-party scrutiny group has also discussed the project behind closed doors for commercial confidentiality reasons.
Opposition leader, Cllr Chris Holley, who took part in the scrutiny discussion, said it was difficult to comment without disclosing what went on in private, but that he would say more in due course.
"It could be a good thing for the city of Swansea," he said of 71/72 The Kingsway. "But I think there are issues in terms of the occupancy of it."
