Osborne has been named preferred bidder for a £14m new college campus in Colindale, North London.
It will build the five-story New Colindale Campus for Barnet and Southgate College, including a construction technology school, a training hair salon and a public library.
The development forms part of a £550m masterplan to regenerate the wider Grahame Park area.
Osborne will work project manager Aecom to ensure vocational training, work experience and employment skills support is available for the college’s students.
Osborne’s business unit director for education John Craig said: “We’re delighted to be preferred bidder, especially in the face of some strong competition.
“New Colindale presents a great opportunity, not only to deliver a striking built asset for the College, but to enable local regeneration and establish a legacy of which everyone can be truly proud.”
