This renovation and expansion of The Nature Conservancy’s Oregon headquarters transforms a dated office building into a collaborative hub that reflects the mission of this environmental nonprofit. Built in the 1970s, the original building’s prosaic exterior and landscaping did little to promote the visibility and identity of this global nonprofit. Inside, the dark, siloed office layouts and lack of sizable meeting or event space posed challenges for this collaborative organization.
To create an outward expression of The Nature Conservancy’s work in Oregon and to connect staff and visitors to nature, the design integrates materials and plantings specific to their priority projects around the state. New landscaping evokes three of the organization’s protected habitats: the Rowena Plateau, the Cascade-Siskiyou region, and western hemlock and cedar forests. The building exterior is completely reimagined with steel cladding that weathers over time, as well as Juniper siding and Cedar decking which were both sustainably harvested from The Nature Conservancy’s conservation sites.
Original Building
The original office building did not convey The Nature Conservancy’s mission, promote the organization to the wider community, or support its collaborative culture and functional needs.
Materials with Meaning
The renovation makes visible The Nature Conservancy’s vital work. The design evokes landscapes across the state through the inclusion of plantings and materials that have been sustainably sourced from the organization’s conservation sites or from regional manufacturers.
The landscape design evokes three distinct natural habitats across the state.
Material for the Juniper cladding and Cedar decks was sustainably-sourced from Nature Conservancy preserves in Oregon.
Central to the upgrade, is a new building addition which contains a community room and roof garden terrace. The addition provides a highly visible gathering space for public events and collaborations with partner organizations. In line with The Nature Conservancy’s commitment to innovative solutions, the addition is one of the first in the US built with domestically-fabricated Cross-Laminated Timber (CLT) panels that are certified by the Forest Stewardship Council (FSC). Other elements of the gut renovation empower the organization’s collaborative culture and work such as new open plan layouts, meetings rooms of varying sizes, staff café/lounge, and dedicated storage space for equipment used in the field.
The new conference and event space helps The Nature Conservancy engage partners and the community in new ways.

The design's new light-filled, open layout supports The Nature Conservancy's collaborative and non-hierarchical culture. Original wood ceilings were refinished and left exposed.
Sustainability is integral to the design and drove the decision to maintain and renovate the original building. To achieve the targeted LEED Gold certification, a blend of high-tech and common sense solutions was deployed. The building’s new rooftop photovoltaics produce 25 percent of its electrical supply, and efficient building systems and fixtures reduce electric consumption by 54 percent and water consumption by 44 percent. The new landscaping and subsurface infiltration system manage all stormwater on site. Practical strategies such as abundant daylighting, operable windows, and the use of local materials enhance comfort and connect occupants to the neighborhood and the greater region.
