The Reality project, from July 24 to 28th took place in Mile Cross, Lakenham, Hellesdon, Mousehold, Heartsease as well as Norwich city centre.
Norwich Youth for Christ threw their resources behind the idea which came originally from student Katie MacInnes.
Director of NYFC, Mark Tuma, said: “Reality went really we. We all had a fantastic week and the young people all worked very hard in the heat of the day. The mornings were taken up with great training sessions.
“There were around 120 people involved and 700 turned up for community barbecues which we laid on in Heartease, Mile Cross, Lakenham and Mousehold.”
NYFC’s Ang Fox, who helped run the project in Mousehold, said: “The young people worked extremely hard litter picking, gardening and running a holiday club. It has been a great week for young people to demonstrate God's love to the community by serving them in extremely hot and trying conditions and seeing amazing results.
“It has really impacted the area and one of the visible results is a renovated garden. Some young people were even planning to return to help finish a major project such is their commitment.”
Andy Vail, who was involved in the Heartsease team, said: “The week was a great success for the young people, who benefited from the whole experience, and for the local community. By the end of the week they were recognising this army of young people in white Reality tee-shirts carrying out good work for free to show that due to their faith in Jesus Christ they have a heart for Heartsease.”
One of the projects involved painting fences and a play area at Heartsease First School. One of the youngsters taking part said: "We are really enjoying it. People seem really positive and are genuinely interested in what we are doing."
Heartsease Churches Youth Worker Danny Doran-Smith, who helped to organise the week, said: “It went really well. Young people are engaging with the community. People are aware of who we are and are recognising what we are doing. It is really positive.
"All these projects were done by the young people from our estate and from different areas of our city. We believe this will be a positive experience in many young people's lives.”
