PROJECT

Teak plank wood and multi-piece porcelain flooring contribute to the
free-flowing conceptual design used in the top four floors of the building.
Placing utilities under the floor increased floor-to-ceiling height, resulting
in taller windows and more daylight.

Access Flooring Saves Energy, Improves IAQ
Additional daylighting and delivery of 100% filtered outside air are
two benefits of placing utilities under a raised-floor system.
