Right The decorative walking surfaces are a material made of thermo-plastic rubber granules with a two-part urethane binder that was poured in place. Above Six thousand square feet of Thermory wood, which is ash (in this case) treated with heat and steam to remove all sugars and moisture thus making it more durable, was used to create the walkway and the cook center's deck. The planks are not attached by nails but rather by clips on the frame. To retain its original brown color, it has to be treated with a particular stain twice in two years at the cost of about $1 per square foot. But it was agreed to forego it here, eliminating maintenance, and allowing it to "bleach" to a gray color, making for a nice contrast with the synthetic turf and the flex surfacing according to project coordinator Santosh George. Instead of a minimum of 6" of clearance from the ground to the walkway - for enough air circulation that the material doesn't heat up and warp - only a 4" gap was needed due to the wood's hardiness. The framing for the walkway and deck, which are ADA compliant, was made of high-grade cedar that has a 20-year warranty.

The goal of the project was to improve and update the existing landscape and hardscape and to enhance the tenant experience and overall development of the garden while retaining the existing infrastructure. The client's vision was to create an outdoor living experience for all to enjoy as if in their own yard, and seamlessly tie the indoor and outdoor to - gether. This included curvilinear surfaces of different materials; amenities such as an outdoor kitchen, fire pit, koi pond, an ornate fountain; and many creative seat - ing elements. Moving Forward Santosh A George, ASLA, MLA, the senior landscape designer at Complete Landsculpture and the coordinator for this project, reports that the scope of their work included site analysis, recom - mendations for landscape improvements, concept and design development, budget - ing, and finally the actual installation as project managers. One of the most innovative aspects of the design and build was that the exist - ing hardscape was not torn out but simply covered by a wooden walkway and deck, synthetic turf and a rubberized surfacing material. "We pretty much put a thin layer on top of the existing surface without remov - ing anything," George relates. The walkway and deck were framed with cedar. Their surfaces, and the clad - ding on pergola's columns, are Thermory wood, which is natural wood that has
