The comedy, written by and starring Miranda Hart, aired on BBC Two for its first two series, where ratings peaked at over 4 million.
"I am very grateful to BBC Two for supporting and nurturing me, and trusting my vision for the show," said Hart. "Two will always feel like home. Now I feel like I am renting a swish apartment that I hope I don't look out of place in or break all the furniture!"
BBC One controller Danny Cohen added: "Miranda has become one of the great comedy stars of her generation. I'm a big fan and know that she will be much loved by BBC One audiences."
The comedienne recently revealed that the new series could be delayed until 2012. In a press release today, the BBC said that the timing of the run "is yet to be confirmed".
