The House of Diversity, Mortensrud Volunteer Center, is a meeting place that promotes positive activities for residents in the area. The center offers a varied program that includes meeting places for women from different backgrounds, as well as activities such as football and social gatherings for fathers. There are also senior meetings on Thursdays, which give the elderly an opportunity to gather and participate in social activities.
In addition to social events, the center offers language training and free Norwegian courses, which can be helpful for those who want to improve their Norwegian skills. For girls and women, training and fitness are organized, as well as a hiking group that meets on Mondays. Gardening is part of the activities at Mangfoldshuset, and there is also an information group that shares resources with the local community. The center is involved in events such as the Children's Festival, where there is a need for volunteers.
