Designed by the council's London-based in-house architecture team, the information and teaching centre in Tunis also includes office space for staff members.
Project architect Sophie Bollier said: 'My background being in interior architecture, I started the building from the inside. I then worked with our local architects to develop its shape.
'We then started the long process of specifying the project to make sure that before it got going we knew exactly what to expect.'
According to the architect, the 1,200m 2building - which houses 13 classrooms - was financed by a local landlord who lets the facility back to the British Council.
'Security was of prime importance, especially considering that work began on the scheme soon after 9/11,' Bollier added.
