Brennan Cox

Founding Partner


Brennan is a landscape architect and urban designer with 19 years of experience working at all scales of the built environment and for all types of clients.  He is a founding partner of GROUNDWORKS Office and amongst a new generation of designers using technology as tool for designing, prototyping and constructing innovative landscapes.  His work seeks to expand the field of landscape architecture and build projects that imbue the complexities of our environmental conditions and promote a strong civic stewardship.  He prefers to solve every problem with a Pentel Sign Pen Model #S520 and a roll of trace paper, and he usually isn’t very far from a tape measure.
