An audit of architects in Ireland has shown around 300 people are not officially registered
More from: Irish exodus continues
The Royal Institute of the Architects of Ireland said the illegal traders will now be urged to legitimise their practice under the Building Control Act 2007.
Professional directories, local newspaper advertisements and other public notices were looked at by the institute and were cross-referenced against names on the official register of all 2,600 architects.
Around 200 were found to be trading illegally because they had no recognised architecture qualification. Another 100 people were qualified but had not registered, institute registrar John Graby told the Sunday Business Post newspaper.
Architects need to fork out as much as 1,200 euro to register and may be refusing to do so in light of the recession and the crisis in the building industry.
Graby said those who practise illegally under the title of architect will be sanctioned by the institute.
