Brunswick Street Baptist Church members have voted overwhelmingly in favour of supporting a deal that would save York House.
The motion for an agreement-in-principle with the City of Fredericton carried by 94 per cent during a meeting Tuesday night.
That deal would see the congregation swap the York House property for three other properties located to the west of the church.
Brunswick St. Baptist Church wants to build a 30,000-square-foot expansion.
The church will get the Knights of Columbus Hall on George Street and two dwellings on Brunswick Street in exchange for the 114-year-old architectural landmark.
