DLR GROUP

The world leader in education, ranked by fee income, last year it earned $63 million from the sector.

It is also second in the world in criminal justice, from which it took $16 million. No jokes at the back about transferable skills, please.

Most of its $120 million+ global income comes from the USA, where it has 10 offices. Curiously, it claims not to have a formal HQ location, instead listing all 20 and its studio in Shanghai equally.

Last year’s wins included a conference centre for Jefferson City in Missouri.

The multi-disciplinary firm also offers engineering, planning and interiors.
