Jobs will be created thanks to an extension at Newhaven Enterprise Centre for small to medium sized enterprises to move into.
The development will be paid for with a £1.9m grant from the Big Lottery Fund and construction could start in autumn this year.
It will provide an opportunity for green and marine technology companies to set up at the centre on Denton Island, linking in with the University Technical College and the Rampion Offshore Wind Farm.
Leader of Lewes District Council Rob Blackman said: “The total investment of £2.25m (£1.9m plus £150,000 from East Sussex County Council and £175,000 from Lewes District Council) will benefit and make a real difference to so many people in and around Newhaven.
“The Newhaven Growth Quarter scheme will create new employment opportunities and support that will help local people back into work, as well as creating a culture of enterprise for young people starting work.
“This is fantastic news for Newhaven and creates a real catalyst for change, offering a unique opportunity for exciting economic growth within the “Clean, Green and Marine” technologies sector, building upon the imminent arrival of the new University Technical College.”
There are five key building projects that will form part of the Newhaven Growth Quarter. These include:
An extension to the existing Newhaven Enterprise Centre to create new space for new and emerging businesses who specialise in the “Clean Tech” sector.
An extension to the Sussex Community Development Association’s (SCDA) nursery and crèche to create more child care places to support parents who want to work.
Construction of new training rooms at SCDA for employability and skills training, to provide local people with new opportunities to develop their careers and business ideas.
A focal point for Newhaven Growth Quarter to be located within the Sussex Downs College campus to act as a Quarter Café and meeting place for all users of Newhaven Growth Quarter.
The creation of an attractive “campus-style” environment for all Newhaven Growth Quarter users.
Lewes District Council led a team that was awarded £1.9m by the Big Lottery’s Coastal Communities Fund to implement the Newhaven Growth Quarter Scheme.
The project has been designed to create and sustain local jobs for local people and to act as a catalyst for growing clean technologies in Newhaven and surrounding area.
The scheme has been developed in partnership with Basepoint which manages Newhaven Enterprise Centre on behalf of Lewes District Council, Sussex Downs College and Sussex Community Development Association.
Principal of Sussex Downs College Melanie Hunt said: “Sussex Downs College is delighted to be a partner in this exciting project.
“We know that skilled people are at the heart of every successful company, and we look forward to working with new and existing businesses in Newhaven.
“Our Quarter Café will enable new businesses, established companies and those in training to keep in contact, and ensure we support learning and development for people in employment, as well as those preparing for work.”
Chief executive of Sussex Community Development Association Penny Shimmin said: “Sussex Community Development Association are delighted.
“The development of Denton Island will support local people to get and retain employment through employability support, self employment support, access and advice and child care; all of which make getting and keeping a job possible.”
