Parker Water & Sanitation District HQ

Parker, CO

This building will house a total of 180 administrative and maintenance professionals across two curved (segmented) levels that share a center point marked by the highest point of the site – inspired by a drop of water’s concentric rings of outward momentum.

The program is roughly split 60:30:10 between maintenance bays, an open-plan workplace, and a high-performance water quality laboratory. The project has undertaken an immersive workplace strategy initiative – combing both administrative and maintenance staff into a shared departmental, flexible, and module office environment.
