A slow-burn hit set in suburban Glasgow, Two Doors Down started as a one-off special in 2013 before the first series was commissioned in 2016.
It revolves around married couple Beth and Eric – played by Arabella Weir and Alex Norton – and their intrusive family members and neighbours.
The storytelling often focuses on small, trivial incidents – in one episode the only significant event is that Alan, played by Graham “Grado” Stevely, has some spare doughnuts.
Season eight will see Beth and Eric cling to their hopes of a quiet life despite the relentless chaos from neighbours Colin, Cathy and Christine – played by Jonathan Watson, Doon Mackichan and Elaine C Smith.
BBC Scotland’s head of commissioning Louise Thornton said it was “fantastic” to see the return of the characters which were “loved by audiences up and down the country”.
Jon Petrie, BBC director of comedy, added: “We’re really proud to bring it back for another series.”
There will also be a run of Two Doors Down live shows at Glasgow’s Hydro in September.
