Mackenzie Crook will star in the six-part series Detectorists, in which he uses his own experiences as a metal detector enthusiast.
Crook will "tap into the world of the male hobby which is very funny and touching", BBC controller of comedy commissioning Shane Allen said.
The BBC is looking to announce a "big name" star to appear opposite Crook in the series, according to Radio Times.
The pair will "embark on a journey of greed, betrayal, rejection and redemption as they hurtle towards Danbury Metal Detecting Club's greatest ever find".
Meanwhile, Miles Jupp will write and star as cookery writer Damien Trench in In and Out of the Kitchen, a three-part series based on the Radio 4 comedy.
Each episode follows Damien and his partner Anthony (Justin Edwards), their builders Mr Mullaney and Steven, and Damien's "terrifying" agent Ian.
In February, the channel will air The Life of Rock with Brian Pern, described as a modern day This Is Spinal Tap from The Fast Show's Rhys Thomas and Simon Day.
The series will spoof BBC Four's own rock documentaries, focused on an ageing rock star and frontman of progressive rock band Thotch.
Paul Whitehouse and Nigel Havers will also star in the comedy, while the likes of Peter Gabriel, Jools Holland, Rick Wakeman, David Arnold and Roger Taylor will make cameos.
Matt Lucas, Michael Kitchen, David Baddiel and Vic & Bob round out the cast.
Graham Linehan's latest three-part series The Walshes will also be broadcast on the channel, co-written by Irish group Diet of Worms.
Scheduled to air in March, the comedy follows a family from the West Dublin suburb of Strollinstown. Tony (Niall Gaffney) and Carmel (Philippa Dunne) are parents to Ciara (Amy Stephenson) and Rory (Rory Connolly).
The children are forced to move back home due to the state of the Irish economy.
Shane Allen said of the new commissions: "This quartet of comedy treats is testament to BBC Four's unique legacy in bringing the audience big name comedy talents in surprising and inventive shows that follow in the footsteps of award-winning predecessors like Getting On, The Thick of It, Twenty Twelve and Screenwipe."
BBC Four previously hinted that it was going to curtail the amount on original comedies and dramas in favour of art-focused programmes.
