South Manchester law firm Gorvins has taken a total of 15,000 sq ft at Dale House on Tiviot Dale in Stockport.
The company is relocating from its current office at 2-14 Millgate, nearby in Stockport, in September.
Gorvins agreed to occupy the fourth, fifth and sixth floors of the building with landlord F&C Reit. Details of the rental agreement were not disclosed.
Lorraine Lockie, managing partner at Gorvins, said: "Gorvins remains committed to Stockport. We were attracted to Dale House by the opportunity to remain at the heart of the business community whilst providing an enhanced working environment for our staff and improved facilities for our clients."
Paul Smith, from King Sturge, joint letting agent acting on behalf of F&C Reit, added: "F&C Reit is absolutely delighted to announce that Gorvins have signed at Dale House, which is fantastic news for the building and the Stockport area in general. Both King Sturge and the joint agent WHR have taken a great deal of satisfaction in concluding this transaction particularly as a large number of other landlords and agents have worked very hard to try and secure Gorvins within their buildings over a long period of time. A fantastic tenant to have within Dale House."
