Larry Oltmanns (born 1951, in Rockford, Illinois, United States)[citation needed] is an American architect.
He has achieved recognition for his work as an architect and master planner of large-scale mixed-use developments worldwide.
[3] His competition-winning design for the new extension to the Melbourne Convention & Exhibition Centre was awarded a 6 Star Green Star environmental rating by the Green Building Council of Australia, the first in the world for a convention centre.
In 2004, following a round of redundancies and management problems with their NATO Headquarters project, Oltmanns chose to leave SOM.
One of his firm’s first projects was the master plan for the $2 billion redevelopment of Euston Station in London.
