O’Shea Wilson Siteworks is an award-winning landscape architecture studio based in Charlottesville, Virginia. We are dedicated to making meaningful places that engage local ecologies, function as habitat and create opportunities for vibrant human community.

We provide design constultation services for projects including university and college planning and design, corporate campus and offices, museum and culturall institutions, public parks and urban design and private gradens.

Through collaborations with architects, engineers, scientists and artists we develop high performance and site specific designs that go beyond sustainability towards regenerative, restorative and equitable solutions for our clients and their communities. We consistently create places that are biophilic, beautifully crafted and democratic.

We believe that designed places must be beautiful, universally accessible and inextricably linked to the natural and cultural history of the site. In all of our work we strive for the creation of memorable and sustaining human habitat. We develop work through an analytical and empathetic reading of the sites, systems and people with whom we work. We see our work as the outgrowth of a process that employs investigation, dialogue and creative expression to fuse the needs and desires of our clients with the inherent qualities and conditions of the places they inhabit.
