ASLA 2003 Design Excellence Award
Westlake Corporate Campus, Circle T Ranch, Westlake,
The design of Westlake Corporate Campus captures the essence of a country ranch—integrating a 650,000-square-foot office building and a parking structure for 2,700 cars with forest, meadow, and ponds. Located on 309 acres near Solana, between Dallas and Fort Worth, the site is an active ranchland. Part open pasture and part post oak savannah, it has two existing ponds, wildflower meadows, and rolling terrain. It was the first land development along the rapidly-developing Highway 114 Corridor in the Town of Westlake, west of Dallas, where many ranches are under pressure by suburbanization. The project met and exceeded all development standards mandated by the town and has become their model for future development.
Through close collaboration with client representatives, the SWA Group determined that the campus should emulate the experience of a ‘country home,’ with buildings, roadways, and garage integrated into the indigenous landscape. Cars are accommodated within a five-story parking structure in order to preserve trees and allow flexibility to create a meadow. To screen the parking garage from the office building, the designers placed them at a distance from each other and provided a covered walkway for shade. The walkway serves as a journey through the landscape’s flowering perennials, grasses, and trees. The building lobby is situated so that it focuses on a mature grove of post oaks rather than the parking garage. The building backs up into wildflower meadows, created with fill from the rest of the site, graded, and planted to appear natural and screen future development beyond its edges. An entry drive preserves the existing forest and integrates new planting for seasonal color.
As requested by the client, meadow grasses and indigenous plant material
evoke the north Texas grasslands. Exterior public spaces are articulated
with flagstone, spring-like water features, and drifts of dry-land plant
materials, such as prickly pear cactus and muhly grass. The use of Texas
sandstone, steel, and glass on both the building and site work established
a palette that harmonizes with the subtle coloration and texture of the
site. Site geometry is purposely non-directional to weave the new site
work into the natural landscape. Roadways are narrow and curbless to express
the idea of a country road and allow water to return to the landscape.
Roadway lighting is placed in trees rather than on poles, and all site
hardware is minimized. Every design element helps to preserve as many
existing trees, plant communities, and habitat areas as possible, and
provides for dam reconstruction, pond reshaping, dredging, and restoration
of edge habitat. In addition, approximately 1,000 new trees were established
for the next generation of forest.

|The watercourses handle site drainage while providing amenity. The “bones” of the watercourses consist of cobbles on grates along the bottom, through which water bubbles up, spreading out in smooth ripples over the surface like a native, aquifer-fed spring. (Photo by: Tom Fox)|

|At some distance from the main building, a pavilion calls employees to wander through the landscape. The pond edge mirrors three different treatments corresponding to natural habitats: a sedimentary stone layer edge, a layer planted with native aquatic plants, and an edge which maintains the natural pond edge of American Lotus.
