Watershed contains six floors of office space, one level of retail, terraces on four levels, 14 vehicle stalls, lockers, showers, and 120 bike racks. Watershed’s glass form sits lightly on a solid base, shifted and recessed, with views oriented towards Lake Union. Enveloped in self-tinting electrochromic glass, it reduces solar heat gain and glare while maintaining daylighting and views. It is topped by a dramatic cantilevered roof, clad in warm cedar, that provides space for an urban apiary and rainwater collection via a cascading sculptural steel art piece conveying captured rainwater to a 20,000-gallon cistern for use in irrigation and toilet flushing. Adjacent, verdant bioswales and terraces stepping down a hillside offer biophilic connections to visitors and tenants while filtering toxic stormwater runoff from the Aurora Bridge overhead.

Retail space lines the main street frontage with outdoor seating areas adjacent. The site rises steeply up to an alley at the high point which provides access to service areas and parking at Level 3. The covered parking is hidden from view, wrapped in curtain-walled office space facing the view.
