Law firm McGrigors is moving into a new office at No 1 The Avenue in Spinningfields, Manchester city centre.
McGrigors has agreed a lease of around 11,000 sq ft spread over two floors, including a 3,000 sq ft client suite, for an undisclosed sum.
The lease has been agreed with developer Allied London and building owner IM Properties.
McGrigors is expected to move into the new premises in March 2011 from the sixth floor of The Pinnacle located at 73 King Street in Manchester.
McGrigors Manchester has a team of over 35 people, having expanded since opening an office in the city in January 2008.
Richard Masters, managing partner of McGrigors, said: "Peter Blackmore, who heads up our Manchester team, has done an exceptional job in establishing an office which provides clients in Manchester and the North West access to a firm with a genuinely national network of offices across England, Scotland and Northern Ireland. We look forward to welcoming existing and new clients into No 1 The Avenue later this year."
Peter Blackmore, head of McGrigors' Manchester office, added: "Following the arrival of several senior hires over the past 24 months, its fair to say that things have been a little cramped in our existing office space."
Clients of McGrigors' Manchester office include Balfour Beatty, including its operations in Sale and elsewhere, Galliford Try, Manchester Airport, United Utilities, and Alstom.
The Avenue consists of 41,000 sq ft with an 8,000 sq ft ground floor retail store let to Armani on a 16-year lease.
Jeweller Phillip Stoner opened a new store within the development on Wednesday 1 December, joining retailers Oliver Sweeney, LK Bennett, Nicky Clarke, Brooks Brothers and All Saints as a tenant at The Avenue.
The upper floors consist of 26,500 sq ft of Grade A office accommodation.
OBI Property LLP acted as agent to McGrigors on the deal.
DTZ and Jones Lang LaSalle are the retained agents on The Avenue.
