What Lango Hansen Landscape Architects does

Lango Hansen Landscape Architects is a boutique landscape architecture practice headquartered at 1100 NW Glisan St #3A in Portland, Oregon, founded approximately in 1999–2000 by Jane Hansen and Kurt Lango. The firm employs roughly eight people, including Principal Kurt Lango, Associate Principals Brian Martin and Kyle Trulen, and supporting designers, and operates primarily across the Pacific Northwest with select projects in Northern California and Nevada. Its portfolio spans four primary use-case segments: parks and public space, multifamily and mixed-use residential development, educational campuses (K-12 through university), and hospitality (hotels, wineries), plus a smaller private residential practice.

The firm's core offerings are professional landscape architecture design services delivered from concept through construction administration. Domain specializations include sustainable stormwater management (rain gardens, green roofs, stormwater planters), urban plaza and courtyard design, inclusive all-abilities playground design, large-scale living wall technology (e.g., the 64-foot Hotel Modera living wall), interpretive placemaking, and adaptive reuse of historic structures (e.g., Flaneur Wines within the Madsen Grain Elevator, De La Salle North Catholic High School renovation). The work is supported by an extensive award record spanning Oregon ASLA, AIA, DeMuro, Gold Nugget, National ASLA, and ULI Global Awards, and was featured as the cover story of Landscape Architecture Magazine in January 2025 for its decade-long Slabtown District engagement.

The business model is fee-for-service professional services, with revenue generated through project-based engagements negotiated per scope and complexity. The firm secures work through three primary channels: (1) co-vendor relationships with leading Pacific Northwest architecture firms (SERA, Bora, Opsis, GBD, Holst, Lever, Hacker, Hennebery Eddy), (2) direct engagement with municipal and institutional clients via RFP and reputation-based selection (City of Portland, City of Salem, Sandy Parks & Recreation, North Clackamas Parks & Recreation District, Portland Parks & Recreation, Tigard School District, Oregon State University, University of Oregon), and (3) ongoing developer relationships for multifamily and mixed-use projects (Cairn Pacific, Capstone Partners, Holland Partner Group, Mill Creek Residential, Prometheus Real Estate, Mack Urban). The firm is privately held by its principals, with no external investment or parent company, and pursues growth through reputation and partnership depth rather than geographic expansion or acquisitions.
