The area now has a complete temple, dining room, two kitchens and bathrooms, with plans to build a playground and grow more fruit trees in the outdoor area.
The community of over 100 people including many children worship in the temple every Saturday although they always remain open for anyone in the community.
"Everybody is welcome here. Every caste, creed or race can come and spend time here and get any help they need," Kumar said.
The temple is used not just for worship but as a space for the Ravidass community to meet and discuss politics and community issues as well as hold social events.
"Our fundamental laws are to sit together, cook together, share together and discuss together," Kumar said.
"This is our second home," he said.
Kumar wanted to thank the builder Stuart Neilson who worked free of charge and the Hastings Sikh community for their ongoing support for the temple.
The Ravidassia religion is a more moderate branch of Sikhism Kumar said, although they often hold events and join with the Sikh temple in Hastings.
Kumar said the wider community of Hastings had been "very supportive" of their temple and construction.
