Following an 'extensive review' by RIBA North, the institute will now merge its regional offices in Newcastle and Leeds in a bid to improve its member services.
As a result, the Tyneside branch will shut its doors at the end of the year.
According to an RIBA spokesman, the move will help both regions prosper and strengthen. He said: 'The economies of scale that result from this office reorganisation will positively enhance RIBA North's regional member services.'
The AJ understands the decision will lead to the creation of a new post of head of strategic partnerships, which will be based in RIBA North's region, and will 'interface with and influence local and regional decision-makers'.
RIBA North's members will continue to be represented by a directly elected regional council.
Peter Buchan, the executive director of Newcastle-based practice RyderHKS, admitted the local branch had been struggling for some time. He said: 'The Newcastle office has been working against the odds, being under-funded and lacking senior leadership.'
He added: 'I would rather see the operations consolidated if it means that these issues will be addressed and RIBA actually becomes a force to be recognised in the regions.'
