Project Description
Co-conceived by architect and contractor, Q21 is an innovative mixed-use commercial and multi-family building in a catalytic location within Portland’s Northwest Master Plan area. The design combines active ground floor retail, second floor office space, multi-story above and below-grade structured parking, a highly diverse mix of apartments and a third-floor resident outdoor courtyard. The 7-story, 200,000 square foot building contains several innovative design features: Sustainably retained and creatively re-invented the existing two-story concrete tilt-up shell on the site (a former auto parts warehouse), preserving some panels in-situ, tilting down and repositioning panels and cutting portals in panels to frame ground floor townhome units. The result is a unique architectural aesthetic expression and a more sustainable building. Pioneered a two-story Type I-A concrete podium below wood construction in Portland. The successful appeal for “over-2” construction helped pave the way for the introduction of seven story “5-over-2” buildings to the city. Integrated a highly diverse unit mix—33 unique unit types from 300 SF micro-studios to three-bed luxury apartments. This facilitated a rapid lease-up and leasing resilience for the developer due to the diversity of units available. Innovative “XXI” steel structural columns at the entrance on NW 21st Ave support a projecting four-story concrete element that accentuates the entry and provides an iconic element for the building. This and other structural feats such as the integration of the existing tile-up structure lead to the Structural Engineers Association of Oregon (SEAO) awarding Q21 it’s 2017 Excellence in Structural Engineering Award for a New Building Over $10M. Minimized below grade structured parking by integrating two intertwined parking ramps in the middle of the floor plate. This necessitated the design of unique two-story, single-aspect townhomes that feature a tall double-height living space at their heart and south-facing covered porches.
