A new building project to transform Swansea that is estimated to be worth around £500 million has been given the go-ahead.

It is hoped that hundreds of new jobs in construction will be created by the work, which will be carried out in the city centre and along the seafront.

Swansea Council unveiled the outline plans late last week, appointing Rivington Land, Acme and Trebor Developments to handle the project.

Construction will take place at a former shopping centre, as well as on the sites of major car parks and a civic centre.

Proposals include the development of several exciting additions to the sites.

These include a 3,500-seat arena, a retail street and a new residential building that could become the tallest of its kind in Wales.

Further plans are being made for a new aquarium and a state-of-the-art research centre.

Both of these could be developed in partnership with Swansea University.

There will be improved links between the city centre and the seafront, while a new cinema and public spaces will also be built.

The council is now to take a closer look at each of the proposals and complete investigation works at each of the sites earmarked for redevelopment.

Estimates now suggest that work, which will lead to the biggest change to the layout of the city since the Second World War, could get under way as early as 2017.

It follows on from the collapse of similar plans made 10 years ago to rebuild Swansea city centre.

Rob Stewart, the leader of the city council, said the work will help to boost the whole of the Swansea economy.

Councillor Stewart said: “Swansea city centre is a key driver of the Swansea Bay City Region economy as a whole, so these proposals are vitally important as we look to boost prosperity, generate more employment opportunities and strengthen the city centre's status as the regional capital of shopping, leisure and recreation.”
