Uche Eneke, 42, spent 13 years in sub-standard temporary accommodation with her two young sons now aged nine and 16, which took a toll on their health, and has three of her photographs displayed.
“I said to my group, wow, he really listened. He looked like he heard me and asked genuine questions,” she said afterwards.
“He wanted to hear my experiences and, crucially, learn what the solutions were. He wanted to know where I found support.
“His backing means everything. Once you get backing from someone like himself, people really sit up. You get noticed.
“Coming from his position he could not want to make a difference, but he does. He has all sorts of brickbats thrown at him and he takes on the chin and gets on with this.”
Artist Robi Walters, who endured childhood trauma in care, also spoke with the Prince.
“He talked to me about his idea, his vision,” said Mr Walters. “How he wanted to educate people about this whole, complex issue. He’s got such a huge public profile and platform and he could choose to focus on anything, but he chooses this. The fact that he has chosen to do this and put his money where his mouth is, well that’s really remarkable.”
The photographer Rankin told the Prince: “I’ve loved being part of it.”
The Prince was also reunited with an old friend, Big Issue seller Dave Martin, whom he has previously teamed up with to sell the magazine on the street.
“Dave, lovely to see you again. How have you been?” the Prince asked
Mr Martin has contributed a piece of work featuring abstract geometric shapes which represent aspects of his life including pathways, a roof over his head and windows to see the light.
He said: “He recognised my work straight away.”
Afterwards, the Prince told him: “If I don’t see you soon, take care.”
Mick Clarke, chief executive of homelessness charity The Passage which helped the Homewards team find artists for the exhibition, said: “What I love about the Reframed exhibition is this gives an opportunity again to put a spotlight on how we’ve got to get homelessness away from something society thinks is inevitable and something that we manage, to something that can be prevented from happening.
“You have this exhibition where it’s taking people on the journey of homelessness and the trauma people have been through, but also the positivity coming out the other end.”
The attraction has three parts: a collection of mainly hand-drawn signs sometimes seen next to a person sleeping rough, artwork commissions, and doors turned into art by young people, from the six areas where Homewards is working, during workshops led by local artists who have been homeless.
