Luke Everitt, 32, says the controversial development is an example of what happens when a council has little opposition.
“The Conservative-led Council has probably done well for the people of Tunbridge Wells in the past, but they have got lazy,” claimed Mr Everitt.
The trade unionist, who works for Unison, added that the wards outside of the town are being neglected.
He continued: “At the moment they [the Conservatives] have a massive majority, which means they have created an echo chamber.
“The Hub is a good example. It is badly developed and it was not what was promised.”
The £10million project to combine a theatre, library, council offices and a medical centre has been scaled back since it was first proposed in 2015 to cut costs, and Mr Everitt said residents are not happy with what is being offered.
He added that while Tunbridge Wells Borough Labour Councillors Dianne Hill and Alain Lewis do a ‘fantastic job’ the town needs a more ‘vocal opposition’.
He said areas like Southborough are crying out for more affordable housing. And developers are being ‘let off’ from their obligations to provide social accommodation.
“The council just sells off land to private developers and lets them off their obligations to provide social housing.
“None of the flats being built by the hub will be social housing. If I were elected I’d be putting pressure on the council chamber to make sure developers are honouring their obligations to provide affordable housing,” continued Mr Everitt.
