Ministers and staff from businesses were among people who took part in a charity sleep-out in a car park in Jersey.
Organisers said more than 120 people took part in the challenge, which has run for six years, on the 11th and 12th floor of the multi-storey building.
The Sanctuary Trust, a homeless charity which provides emergency accommodation for men, said about £23,800 had been raised so far as a result of the event at Pier Road car park on Friday night.
The trust said Housing Minister Sam Mezec participated in the challenge, adding the oldest sleeper was 75 years old and the youngest was aged six.
'Critical need'
Tim Ringsdore, chairman of the Sanctuary Trust , said the event, which gained about £35,000 in donations in 2023, aimed to raise awareness about homelessness.
"Given how cold it was, everyone appreciated the hardship this can cause," he said.
"All money raised will go towards our running costs to ensure our team can continue providing the diverse range of support our residents require.
"Our vision is to tackle homelessness in our community and this event certainly helps this aim and we really appreciate the generosity from everyone who supports us."
Organisers said director of locals services Paul McGinnety took part in the event, as well as people from Jersey Youth Service, Specsavers, JT Global and Andium Homes.
The trust's general manager, Sarah Tumelty, said the atmosphere was "special".
"Despite the cold and windy weather, so many people came together in solidarity, which was inspiring to see," she said.
"This effort will raise awareness and highlight the critical need for support and compassion for those experiencing homelessness in our community."
