Baxter, who heads up Glasgow-based ‘architectural and interpretation consultancy’ Neil Baxter Associates, will take up the role under the title RIAS secretary treasurer.
In June 2007 Wrenn announced her resignation from the incorporation’s top ‘officer’ position after a two-year stint, to be nearer her husband Richard Parnaby – a professor at the University of the West of England in Bristol.
Since her departure in August the role has only been filled on a temporary basis.
Now Baxter, who has taught architectural history at the Mackintosh School of Architecture and previously worked for the RIAS as an assistant secretary, has been unveiled as her replacement.
Speaking about his appointment Baxter said: ‘The RIAS is the only wholly autonomous body within Scotland representing the interests of the architectural profession and promoting the quality of our national architecture.
‘It is a key voice in influencing attitudes and improving Scotland’s built environment.'
He added: ‘The RIAS is a venerable institution with a rich history. It is also a pro-active, member-led body. I greatly look forward to working with the superb RIAS staff and membership.’
