The Church of the Good Shepherd in Poole wants to raise £1.5 million to replace its current home.
Although the church was established in 1931, the church still meets in the first building in the area, which was a 'temporary' wooden structure.
The original church building was expanded in 1949 with a hall and rooms added, which are used by a large number of church and community groups.
According to its Just Giving page, the plans are to create "an all-new building which combines excellent church and community facilities, serving the local area for the rest of the 21st century and beyond."
The plans include a worship area which is also suitable for other gatherings, a hall of a similar size to the old one, a fully-equipped kitchen, a foyer/coffee bar, a meeting room, office, toilets, storage and a 20 space car park.
Rev Peter Homden from the church told Premier News Hour: "We've always had an amazing history in the parish of our outreach to children and young people and that's developed over the years and evolved.
"We're involved in various other projects in the area, specifically with our physically and mentally disabled folk.
"The church has to see itself as helping more socially in the community but we specifically have a history of it since it's been built."
The planning application was approved by the Borough of Poole last year and the project is supported by the Diocese of Salisbury and the Bishop of Sherborne, Rt Rev Karen Gorham.
