Las Colinas, Texas
Talley Associates provided complete site planning, design and landscape architectural services for this 200,000 square foot corporate office headquarters.
In response to a steeply sloping site, parking is organized in a series of terraces, linked to the south plaza of the building by a pedestrian spine, expressed by bosques of trees, pedestrian scaled lighting, natural grass plantings and a series of precast concrete steps. This plaza features large plantings of timber bamboo, a cold hardy species which provides year-round foliage and texture and defines pleasant outdoor rooms. Black Mexican beach stone and green decomposed granite are used as ground plane accents.
The visitor parking area is treated as a ‘curbless’ plaza, featuring scored and sandblasted concrete paving, a grove of pond cypress trees and a vine covered architectural parking canopy. Drainage is designed to flow into a bioswales, limiting storm drainage and recharging and feeding the landscape. This was the first example of natural grass plantings responding to prairie conditions in Texas.
