Peaches Geldof was planning to open a vintage clothes shop with her husband Thomas Cohen before her death.
The couple, who married in 2012, were considering starting up a business in London after their financial income allegedly began to plummet following the break-up of Thomas' band S.C.U.M in January 2013.
A source told the Daily Mail newspaper: "Thomas was really determined because he knew financially things were a bit of a struggle at home and he wanted to show Peaches he could contribute to their family budget. Peaches really encouraged him and wanted to be part of the business."
However, Thomas, 23, is determined to continue building the business following the death of Peaches last month because he needs something to take his mind off his grief.
The source explained: "Now that she's [Peaches is] gone Thomas' family and friends have been encouraging him to keep the dream alive and continue going for it.
"Thomas' older sister Holly is involved with the plans and she and Thomas are looking at opening a shop in London. They still need to find the right location for it."
As well as juggling a potential new shop, Thomas has also become the sole carer of the couple's sons Astala, two and Phaedra, one, following their mother's passing.
The former musician was left heartbroken after he discovered his wife's lifeless body "slumped" across the bed at their home in Wrotham, Kent, on April 7.
An inquest heard last week that heroin was "likely" to have played a role in the blonde beauty's death.
However, police have since released a statement insisting Thomas is not under suspicion of involvement in her death.

Kate Hudson has reportedly "wrecked" her friendship with Jessica Alba.
The actresses, who developed a close bond after starring together in 'The Killer Inside Me' in 2010, have allegedly gone their separate ways since the blonde beauty began dating Muse frontman Matthew Bellamy four years ago.
A source told RadarOnline.com: "Kate has wrecked the friendship and Jessica pins the start of their troubles to the beginning of Kate's relationship with Matt a few years ago."
Kate, who shares two-year-old son Bingham with Matt, has reportedly adopted the mindset that she's "rock and roll royalty" since becoming engaged to the musician in 2011.
The source explained: "Unfortunately, Kate has become not a nice person since she's been with Matt.
"It's sad but Kate and Jessica's friendship is completely done. They used to be so close, too."
Rumours that Kate and Jessica's friendship had deteriorated began to swirl last month when the 'Something Borrowed' star celebrated her birthday.
Kate, 35, was joined by Demi Moore, Reese Witherspoon and Nicole Richie, at the No Name Bar in Hollywood, but Jessica, 33, was no where to be seen.
However, the brunette beauty - who has daughters Honor, five, and Haven, two, with her husband Cash Warren - has been busy with her business The Honest Company, which creates toxin-free household goods, nappies, and body care products.

Elle Fanning dreams of being a professional ballet dancer.
The 16-year-old actress takes part in a dance class at least five times a week and she admits she would love to pursue it as a career but she doesn't think she's good enough.
Speaking to Scarlett Johansson in the May issue of Interview magazine, she said: "I go to ballet, like, five days a week and I love it so much, but that's the hardest thing I'll ever do in my life, no doubt. You're good or bad, and that's it. That would be hard to pursue as a career, but in my dream that would be the thing."
Meanwhile, Elle - whose sister is Dakota Fanning - surprised herself with her favourite class at school because she thought she'd be into something more performance-led, such as music or drama, rather than science.
She explained: "My favourite subject is science, which is so weird because I would think that my favourite subject would be, I don't know, something more artistic. I only have two more years left now because I'm a sophomore. But I'm also excited to get out of school."
However, despite her eagerness to finish up as a student, she insists she's learnt a lot about herself as a person since attending the school in fourth grade.
She said: "I was homeschooled up until third grade, and I liked it because my grandma taught me, and I loved being with my grandma. But then I didn't really have any friends, none my own age. So my mum put me in school in fourth grade. It's cool because I've realised things about myself that I wouldn't have if I weren't in school."

Pete Wentz wants the sex of his unborn child to be a "surprise" until the birth.
The Fall Out Boy bass player and his girlfriend Meagan Camper are set to welcome their first child into the world later this year, but they've decided not to find out whether they're expecting a boy or girl until the tot arrives.
Speaking to E! News, he said: "I don't know yet [whether the baby is a boy or a girl], [but] I think we'll probably do a surprise on this one."
Pete - who already has five-year-old son Bronx Mowgli with his ex-wife Ashlee Simpson - is looking forward to meeting his new bundle of joy in coming months.
He explained: "What's more exciting than having the little pitter patter of having another little gremlin running around and now it will be two-on-two."
The 34-year-old star and his model beau announced their baby news in February by posting a picture on Instagram of them kissing and Pete touching Meagan's stomach.
He accompanied the snap with the caption: "We're super excited to announce we're expecting a baby!"
The couple, who began dating in September 2011, have been hoping to start a family for a while.
A source said previously: "They've been planning on this for a while. And they're really excited for Bronx to have a new little buddy.
"Meagan is a big sister and has a great relationship with Bronx. She's naturally maternal so this is perfect."

Dame Helen Mirren is "mesmerised" by Twerking.
The 68-year-old actress admits she loves the butt-shaking dance move and she tends to get her inspiration from watching Beyoncé, 32, wiggle her hips on stage.
She told HELLO! magazine: "I'm a huge fan of Beyoncé and I do love to Twerk. I am mesmerised by it. It's unbelievable how they do it. I always like it when a new dance arrives on the scene."
The blonde beauty even had a go at shaking her derrière on stage at Harvard University in Cambridge, Massachusetts, after accepting the Hasty Pudding Theatricals' Women of the Year award in January.
However, Dame Helen admits the energetic dance move didn't come easily to her and she may have had to practice a few times in front of a mirror beforehand.
When asked if she secretly practised in front of a mirror first, she replied with: "I actually might have done that".
The Woman of the Year honour is given to performers who have made lasting contributions to entertainment.
She said of her award at the time: "How very saucy of the Hasty Pudding organisation to offer me their award. As someone who adores Pudding in all its manifestations ... Suet, Christmas, Treacle, Bread and Butter, Yorkshire, Plum, Figgy, etc., etc., I am so looking forward to the famous Hasty Pudding."

Zac Efron feels a "weight" has been lifted after he spoke out about his battle with drugs and alcohol last month.
The 26-year-old hunk, who sought treatment for addiction twice last year, is glad he opened up about his personal struggles because it was a relief to lift the lid on his secret.
Speaking on the 'Today' show this morning (05.05.14), he said: "It was a weight off my chest. It was great. It was a fantastic time. It was a rough year."
The actor is currently starring alongside Seth Rogen in the comedy 'Bad Neighbours' and he's happy he's finally getting his career back on track following a difficult year.
He explained: "It's kind of funny -- 'Bad Neighbours' is such a great icing on the cake for all of this.
"I was able to kind of channel all of that and put it back into this movie. I feel great. I feel really blessed to be here working with this group of guys. I couldn't be better right now. I'm really excited."
Meanwhile, Zac - who shot to fame after taking on the lead role in 'High School Musical' in 2006 - admitted last month he felt humiliated when his "mistakes" were made public.
He said at the time: "I was drinking a lot, way too much. It's never one specific thing. I mean, you're in your twenties, single, going through life in Hollywood, you know?
"Everything is thrown at you. I wouldn't take anything back; I needed to learn everything I did. But it was an interesting journey, to say the least."

Orlando Bloom has sold his Hollywood Hills home for $3.9 million. The 37-year-old actor has managed to offload the mansion, which he bought in 2007 for $2.7 million, in California after slashing the original asking price by $600,000. The 3,248 squa...

Hayden Panettiere has put her wedding on "hold".
The 24-year-old actress and her fiancé Wladimir Klitschko have put off setting a date for their big day due to the current fighting in Ukraine, as the boxer's brother, Vitali, is involved in the reform efforts over there.
Speaking to Parade magazine, she explained: "Everything that's happening in Ukraine definitely put a hold on things. But we have time."
However, the blonde beauty, who announced her engagement in October, has already decided she'll be a "sexy and youthful" bride when she walks down the aisle.
She said previously: "I would like some really long, loose boho beach waves and just a nice golden tan.
"I want to be classy and elegant and sophisticated, but I also don't want to forget my age. I want to be comfortable. I want it to be just sexy enough, but youthful at the same time. I don't want to look so done up."
Meanwhile, the 'Nashville' star hasn't started planning for her nuptials, but she offered a small tease about the event.
She said: "I love colour, so that will play a big part."

Peaches Geldof's sister Fifi has become engaged.
The late star's older sibling, 31, who has largely lived her life out of the spotlight, is set to walk down the aisle after her boyfriend Andrew Robertson, 33, popped the question.
Fifi announced her engagement on her Instagram account over the weekend by posting a picture of a gorgeous diamond sparkler on her ring finger.
She accompanied the snap with the caption: "Boydonegood (sic)".
It is not yet known when the happy couple will tie the knot, but it is believed their wedding will take place next year, as the family are still grieving following the sudden death of Peaches, 25, last month.
A source told the Daily Mail newspaper: "They're going to hold the wedding in July next year. I think we all need a happy family event now."
However, Fifi isn't the only one planning to get hitched as her father Sir Bob Geldof recently proposed to his long-term girlfriend Jeanne Marine after 18 years together.
Bob, 62, began dating 49-year-old Jeanne after meeting at a dinner party in Paris, where he had fled to after his divorce from Paula Yates - the mother of his children Fifi, Peaches, and Pixie, 23 - in 1996.
Paula died of a heroin overdose four years later, and the 'I Don't Like Mondays' hitmaker took on the care of her and the late Michael Hutchence's daughter Tiger, now 17.
Meanwhile, toxicology tests revealed last week Peaches, who was found dead on April 7, was "likely" to have died from heroin after the drug was found in her body.

Kendra Wilkinson wants her son to act as a "bodyguard" for her unborn baby daughter.
The former Playboy model, who is expecting her second child with husband Hank Baskett, is trying to encourage her four-year-old son Hank Jr. to look after his younger sibling when she's born into the world in coming weeks.
Speaking to Us Magazine, she explained: "We're trying to empower him and make him feel like he has a role, like he's a little bodyguard. He's taking it on. Every day it's like, 'I can't wait to teach my sister this!'"
The 28-year-old beauty believes she's developed a closer bond with Hank Jr. since falling pregnant with her second child last year because she wants him to understand that he's got a little baby sister on the way, who is equal to him.
She said: "Little Hank and I are becoming so much closer. Our hearts are meeting more, we're talking more.
"We want little Hank to understand there's a little girl coming into our lives."
Kendra recently admitted her second pregnancy has been "brutal" but her husband Hank, whom she married in 2009, has been trying to make it easier for her.
She said: "[He] makes sure my every day is perfect. Like yesterday, he pulled me over, sat me on his leg, and looked me in the eyes and said, 'Kendra you're so beautiful, I know you don't feel it.' I started crying."

Cody Simpson has split from his girlfriend.
The 17-year-old singer has called time on his relationship with model Gigi Hadid following a year of dating after their busy schedules put a strain on their romance.
A representative for the Australian hunk told E! News: "Their busy schedules and living on opposite coasts have made it nearly impossible for the two of them to give the relationship the attention that it needs."
The former couple appear to have ended on good terms and are determined to remain friends in the hope that, one day, they might rekindle their romance.
The representative explained: "They decided that rather than let things sour that they split up in hopes that their lives might someday bring them back together.
"They remain close friends and will continue to show their support for one and other."
Cody and Gigi, 19, haven't be seen together since April 8 when they were photographed at the Radio Disney Music Awards in Los Angeles.
Meanwhile, the 'La Da Dee' hitmaker doesn't appear to be letting the split get to him as he has decided to throw himself into his music and work on his album.
He wrote on Twitter last night (04.05.14): "this next album feels like my first. feelin so new. this is MY album too. older with the confidence to get the artistic freedom I've needed. (sic)."

Carmen Electra is "happily single".
The 42-year-old actress recently split from clothing mogul Tal Cooperman after their brief romance began to fizzle out, but the blonde beauty doesn't appear to be on the hunt for a new lover as she's enjoying being on her own.
She said: "I'm happily single."
However, Carmen, who had a brief relationship with Simon Cowell last year, hasn't ruled out another relationship in the near future, but insists she will take her time with it.
She explained to E! News: "I'm a relationship girl. I've always been in long-term relationships, so you know, this is the first year that I'm actually taking my time and not jumping into anything and taking it slow and having fun."
Although, the model - whose real name is Tara Patrick - admits it takes a certain type of guy to catch her attention.
She added: "Obviously, he has to be somewhat of a bad boy because I'm always attracted to that."
Carmen recently sparked rumours she had rekindled her romance with ex-husband Dave Navarro, whom she married in 2003 before divorcing him in 2006, after he posted a picture on Twitter of them touching tongues.
Carmen was also married to Dennis Rodman in 1998 before their romance ended in 1999.
She also got engaged to rocker Rob Patterson in 2009 before the pair split up in October 2012.
