Below The River, which "follows the curve of the river" from Stockwell to Deptford, will tread a similar path to the Kentishtowner but with established broadsheet journalist and Londoner Kate Burt at the helm.
"There will be a regular a 'why it matters' comment piece each Monday, a Q&A each Tuesday and a meaty Wednesday picture story which explores an intriguing bit of local, community history each week," Burt explained to Journalism.co.uk.
Burt and her team will be publishing six days a week, similar to the original model for the Kentishtowner, but will be recognisably different from the north London hyperlocal as Burt lays her own editorial stamp on the content.
"I am also very much about community," continued Burt. "People and their stories are what has always fascinated me as a features journalist and I aim to make this a prominent and regular angle."
This is the second title from London Belongs To Me Ltd, the parent company for Below The River and the Kentishtowner, which was set up after the company's founders securing funding from NESTA to specialise in the creation and management of sustainable digital publications.
Stephen Emms, who set up the Kentishtowner and London Belongs To Me, and Burt both told Journalism.co.uk that they hope to set up more sites and that there were plans for further additions to the stable.
The Kentishtowner was recently nominated for Best Digital News Service at the Newspaper Awards 2013 alongside The Guardian and Sunday Times.
