The Big Issue in the North has sold its base in Manchester's Northern Quarter district for £1m to Addiction Dependency Solutions.
The charity bought 135-141 Oldham Street in 1997 for an undisclosed sum following a fundraising campaign and with grants from the National Lottery and English Partnerships.
ADS already occupied the building as tenants prior to purchasing the building. The Big Issue in the North will now find new premises in the city.
Brian Ghatan, commercial property solicitor at Cobbetts, advising the Big Issue in the North, said: "It is fantastic news that these charities have been able to assist each other in working towards their future objectives. The deal is also a positive sign for the North West market, especially given both parties' status as charitable organisations."
Caroline Price, director for the Big Issue in the North, said: "We are delighted that the sale of the Oldham Street building is complete, and our former home is still being used to provide important services to people in need. The sale of the building means that we can purchase new premises for The Big Issue in the North, which is better suited to the needs of the magazine and the vendors selling it."
Pannone advised Addiction Dependency Solutions.
