Catalyst Capital has secured planning consent for the refurbishment of Grade II listed Arkwright House in Manchester city centre.
Built in 1937, the building comprises 86,970 sq ft over eight storeys, but Catalyst will increase this to 105,000 sq ft.
Sheppard Robson designed the scheme.
GVA director Chris Cheap said: “The key to unlocking this building’s potential is to provide a large, efficient, flexible floorplate for today’s office occupier and to improve the interior quality of space in order to create state-of-the-art accommodation set against the backdrop of the building’s original features.”
Construction is expected to begin the second quarter of this year, with completion in 2016.
Deloitte Real Estate North West acted as planning consultant for Catalyst.
GVA and CBRE are joint leasing agents.
