The last two events, held under lockdown in October 2020 and March this year, proved so popular with both adults and children that the charity is busy getting ready for next month’s repeat event, this time marking World Homeless Day.
Following on from the success of the March event, which raised £55,000, the evening schedule will include stories, a quiz, a presentation for younger participants, and den building activities.
Alabaré spokeswoman Gemma Lee said: "It’s time to get creative and get your sleeping bag and blankets and find somewhere unusual to sleep for the night!
"The event invites people who wish to take a stand against homelessness and as it is a virtual event it enables people from all across the country to join together whatever their age, to help raise vital funds to help those who have faced the crisis of losing their home.
"The whole evening will be raising funds to help Alabaré provide support to those facing incredible difficulties during the pandemic and beyond.
"During the evening Big Sleepers will also hear from those who have benefited from the support that Alabaré and their supporters make possible."
Alabaré supports homeless adults, young people, veterans and those with learning disabilities but its fundraising activities over the past 18 months have been dramatically hit by the Covid-19 pandemic.
Across Salisbury, the charity runs several supported housing buildings catering for low to high level needs including two Homes for Veterans, Parent & Baby, development centres for vocational training and activities for vulnerable adults with a variety of needs, as well as the Salisbury Street Project Drop in Centre.
There is still time to sign up to take part in the Big Sleep at Home and raise cash to help the homeless.
Why not involve your friends and family by doing something creative and heartfelt this autumn, and together help rebuild lives this World Homeless Day.
