The church has bough the freehold of the 24,000 sq ft building after securing change of use consent from industrial and warehouse to worship.
Churchgoers are already attending services at the building even though refurbishment will not be complete until September.
Graham Young, of agents Douglas Duff which handled the sale, said: “Although the property is in a modern business park Northwest of Central Milton Keynes surrounded by industrial and office occupiers, it is also close to the Greenleys and Bradwell residential areas.
“This prompted us to consider alternative uses outside the normal commercial spectrum and the ample private car parking and adjoining land were features that appealed to New Life Church which has been expanding rapidly in the local area.””
Senior Pastor Richard Wightman (pictured) said:””Over the last five years, weâ€™ve been growing at 30 per cent a year in New Bradwell and we now have a membership of more than 300. When we started looking for larger premises, we found the only buildings big enough were commercial warehouses.
“”Some business people have the impression that churches have no capital and no substance, and may not take churches seriously, so I am pleased that Douglas Duff addressed our requirements professionally and we are grateful to Milton Keynes Council for thinking beyond the designated guidelines to allow an industrial building to become a place of worship.””
