The project was launched by Joanne Vines, founder of the Rucksack Project, earlier this year after Stagecoach donated a vehicle.
Highbury College carpentry students rolled up their sleeves to help transform the double-decker bus into a homeless shelter where people can cook, wash and sleep.
The students have spent months building 12 beds for people who would otherwise be on the streets and their work will go towards their qualifications.
Cathy Ellis, Managing Director Technical Professional said: “We were keen to be part of this exciting and rewarding project because we are very passionate about our community and truly believe this will help shape the lives of dozens of needy people.
“By taking part in this project, the students have also gained the kind of real-world work experience that employers look for while giving back to the community.”
The bus, which will be stationed at St Agatha’s Church in Hope Street, Landport, also features showers, toilets, a kitchen and seats fitted by other organisations across the city.
Now, Joanne is preparing to welcome its first residents onboard and give them a chance to get their lives back on track.
The Bus Project will be officially opened at a special event for the public in Fratton Park from 12-2pm on Sunday 26th November.
After the unveiling, it will be towed to its permanent parking spot at the church.
