The singer left her former group the Sugababes back in 2009 and has admitted to feeling "down" in the month following her departure.
However, the 26-year-old has maintained that she had no intention of rush-releasing new material after leaving the group and wanted to take her time over her debut solo record.
Buchanan told BBC Radio 1's Newsbeat: "I know a lot of the times when someone leaves a group they rush into it. That was the last thing on my mind."
She added: "So this year I've been making sure that I don't rush it, making sure that the image was right and just doing music that I love to do.
"I think that's where it starts, you need to really love the music that you do."
Buchanan also revealed that she has been working with Britney Spears and Kylie Minogue songwriter Cathy Dennis on her material, which she describes as having global appeal.
"It's an international sound but not necessarily pop music or R&B music," she explained.
Buchanan was unable to confirm a release date for the album, saying that she keeps getting offers to work with new people.
"Every time we lock down there's always someone else who wants to work with me," she said.
"I haven't exactly got a set date - the most important thing to me is to make sure that the album is fire."
Sugababes band member Amelle Berrabah recently confirmed that the group had met Buchanan at an event, adding that it was good to get "closure on everything that's happened".
