Law firm Slater & Gordon is close to agreeing a deal to take 100,000 sq ft of prime Manchester office space at 58 Mosley Street, the former head office for Cobbetts.
The 104,000 sq ft building is owned by Bank of Ireland Asset Management, held in its New Ireland Pension Property Fund.
Slater & Gordon is understood to be taking the space at £22.50/sq ft on a 15-year lease with a substantial rent-free period at the outset.
The building has been vacant since rival law firm Cobbetts went into administration in January 2013.
The Australian-listed Slater & Gordon acquired Manchester-based Pannone in February 2014. Pannone currently occupies three neighbouring buildings at 123 Deansgate.
CBRE and Cushman & Wakefield acted as joint letting agents. OBI advised Slater & Gordon.
All parties declined to comment.
