LMN Architects, one of Seattle’s largest design firms, is packing up its Seattle studio and heading to the newly renovated Washington Park building in Pioneer Square. The waterfront-adjacent landmark recently reopened after a major overhaul, and LMN is slated to move in next year.
According to the Puget Sound Business Journal, the firm has signed a lease for roughly 50,154 square feet, making it one of the Seattle area's biggest office deals in the second quarter of 2026. The outlet reports that LMN plans to begin occupying the space next year.
Washington Park's comeback
The Washington Park building at 118 Alaskan Way S wrapped up a renovation in 2023 and now offers about 52,809 rentable square feet across three floors plus a penthouse, complete with a rooftop deck, showers and bike storage, according to Washington Park. The restoration also picked up recognition from Historic Seattle as a standout preservation project.
Built to last, finally occupied
The property dates back to 1890 and spent years largely overshadowed by the old Alaskan Way viaduct. The Daily Journal of Commerce reports that LMN will be the building's first major long-term tenant since the restoration. City historic records still list the building under its original Lowman & Hanford printing identity at 68 S Washington St, a reminder of its deep Pioneer Square roots.
LMN's local footprint
As noted by LMN Architects, the firm already has a creative foothold in the neighborhood through The Shop, a 7,000-square-foot fabrication and event space at 723 1st Avenue that supports prototyping and public programs. The company also maintains a wide-ranging portfolio of civic, cultural and transportation work across the region.
Why this matters
Securing a high-profile local architecture firm for a restored waterfront building reads as a concrete vote of confidence in downtown Seattle's office market and in Pioneer Square's long-term revival. The Puget Sound Business Journal flagged the LMN deal as one of the quarter's largest office leases, a distinction that could nudge more creative and design-focused tenants to give the district a serious look.
Leasing information for Washington Park lists the Broderick Group as the contact for any remaining space, signaling the building's pitch as a boutique, high-end office option near the waterfront. Once LMN settles in, the firm is expected to bring a steady stream of employees and visitors into Pioneer Square, adding more daily life to the neighborhood's retail and arts corridor.
