The charity has recruited Graeme Russell, the high-profile former head of Manchester's CUBE Architecture Centre, to work as head of programming, working with its director Charles Knevitt.
It was considered only a matter of time before an arts organisation decided to turn to Russell.
The former theatre expert left his post as the CUBE gallery's director earlier this year after it emerged that it was suffering serious financial problems.
However, in his time running the gallery and architecture centre it became respected as probably the UK's most successful.
Speaking of his appointment, Russell said: 'For me it's about contributing, under Charles Knevitt's direction, to the expansion of the RIBA Trust as one of the most innovative and exciting architectural centres in the world.
'For our programme to have real merit, real impact and the ability to engage audiences beyond the professions, it must reflect a multitude of different cultural facets, including all urban design disciplines. It also needs to communicate the complex interrelationships between art, architecture and design.
'Retaining an edge is key. We have to present alternatives through many different means - in particular through exhibitions, education work, advisory and consultancy roles, and related cultural practice.
'Moreover, we have to stimulate new thinking on past, present and future issues to do with architecture, design and the built environment - all of which I believe are essential in delivering built environment excellence here in the UK,' he added.
