The Newcastle chambers of Richard Bloomfield, 148 West Road, has become the first Newcastle set to open outside the city centre.
Its annexe, at 2 Lansdowne Place, Gosforth, aims to attract local business away from the other four sets based in the city centre.
A chambers spokesman said: "The other chambers are around Quayside. We have been successful in west Newcastle. Now we hope to do as well in the north.
"There are a number of solicitors in Gosforth who we think will appreciate being able to hold local conferences with counsel."
