Alliant Systems has packed up its Pearl District digs and reopened its Portland headquarters in a freshly renovated two-story office in Goose Hollow, trading warehouse-chic for a spot a short walk from Providence Park and within easy reach of downtown clients and transit.
According to the Portland Business Journal, the mechanical-construction firm bought the Goose Hollow building in 2024, then made the move after its former Pearl space became too cramped. The outlet reports that the deal capped a decision to grow inside Portland’s urban core rather than decamping for the suburbs.
Commercial property records list the new headquarters address as 831 SW 17th Ave, describing a street-level office of roughly 8,378 square feet with front-door access to MAX light rail. Crexi notes the site sits about a block from Providence Park, a location that doubles as a recruiting perk for staff and a convenient landmark for visiting clients.
Alliant Puts Fresh Shine On Former Fortis Office
Alliant Systems says it marked the move with a grand-opening event earlier this month, following a full two-story renovation of the former Fortis Construction office near Providence Park. In its announcement, the company thanked general contractor Fortis Construction and Woofter Bolch Architecture, and highlighted a new layout that boosts meeting and collaboration space while adding showers and other employee amenities.

Why The Move Matters For Local Building Work
The new headquarters is also framed as a strategic play. Alliant says the relocation supports its growth in building-performance, controls and energy services, which the firm emphasizes as key offerings for local projects and for helping clients comply with Oregon’s Building Performance Standard. In its announcement the company wrote, “We remain bullish on Portland, and are proud to continue our commitment to the city in which we live and work.” Alliant Systems
The move keeps a regional mechanical contractor firmly rooted in downtown Portland and adds another visible commercial tenant to Goose Hollow’s blend of offices and stadium-adjacent businesses. The Portland Business Journal has tracked the purchase and relocation as part of its broader coverage of the city’s real estate and development scene.
