Councillors on the local authority’s planning committee approved a proposal to create a four-storey office block on the former Adur Civic Centre car park in Ham Road, Shoreham.
Work on the development, which has been supported by £1.8 million of funding from the Coast to Capital Local Enterprise Partnership, will start in the coming months.
With planning approved, Adur leaders can now reveal the site will be used by Focus Group, a Southwick-based communications company, which has outgrown their current premises.
Brian Boggis, Adur District Council’s executive member for regeneration, said: “This is a prime example of a council doing everything it can to provide a platform to drive forward development.
“In these straitened times, many local authorities across the country are having to cut back on putting money into their communities. But as a council we realise that sometimes you have to invest before the wider community reaps the rewards.
“By maximising the potential of council land and using public money prudently, we are safeguarding local jobs while generating a return for the taxpayer.”
The development will bring back into use the car park site which has been largely vacant since the Civic Centre closed in 2013.
The 2,780m2 of commercial space will be designed for flexibility and spread over four floors.
The scheme will also incorporate 70 car parking spaces, some of which will be underneath a wing of the four-storey building.
Planners admitted it would form a significant new feature on Ham Road, and would ‘plug the gap’ in the streetscape between Glyndebourne Court and Dunelm Mill.
Ralph Gilbert, managing director of Focus Group, said: “I’m delighted to announce this link-up with Adur District Council. It is a great example of a council helping local businesses grow.
“Over the last ten years we have gone from two staff working from a home office to a respected company operating across the UK with hundreds of staff.
“We are really excited to be staying locally at a fantastic new office which will help us to keep on growing - that’s good news for us, the council and the community as a whole.”
The development is part of a wider revamp of the Civic Centre site.
Across the road to the south, the former red-bricked council headquarters has been demolished and the site has been fenced off.
Adur District Council has earmarked the land for a mixed-use site with the plot set to be marketed in the New Year.
Jonathan Sharrock, chief executive of Coast to Capital said: “Shoreham is a great place to live and work and protecting IT skills is vital to the success of the area.
“We are thrilled to be part of a project that will not only safeguard existing local jobs but help provide improved facilities which will benefit a large number of employees, the rewards of which will be felt across the wider community.”
