LMN Architects

Who LMN Architects Is

LMN Architects is an architecture and planning studio headquartered in Seattle, Washington. The practice operates as a single blended studio of approximately 100 design professionals led by eight partners, deliberately avoiding separate departments so that architects, planners, interior designers and computational specialists work side by side on the same projects. That structure is central to how the firm describes itself: one interdisciplinary studio built around research, curiosity and dialogue.

Core Services

The studio offers a full range of design services from early feasibility work through construction administration.

• Architecture - new buildings, additions and adaptive reuse across public and institutional sectors
• Urban design and planning - campus frameworks, district planning and civic placemaking
• Interior design - lobbies, learning environments, performance spaces and workplace interiors
• Design research and computational design - simulation, parametric modelling and material exploration through the studio's in-house research and fabrication work
• Sustainability consulting - energy, carbon and wellbeing analysis integrated into the design process rather than bolted on

Sectors and Building Types

Convention and Civic Buildings

LMN is widely recognised for large-scale public assembly architecture. Its portfolio includes the Seattle Convention Center Summit Building, the Austin Convention Center redevelopment and the Dayton Convention Center renovation - complex urban projects that must absorb enormous crowds while still contributing positively to the surrounding streetscape.

Performing Arts

Acoustically demanding cultural venues are a long-standing specialism, exemplified by the Diego Rivera Performing Arts Center at City College of San Francisco. These projects combine technical acoustic performance with the civic ambition of a public cultural building.

Higher Education and Research

A substantial share of the studio's work serves universities and colleges. Recent commissions include the Falling Leaves Foundation Medical Innovation Building at UC Irvine, the John and Marcia Price Computing and Engineering Building at the University of Utah, the Computing and Data Science Building at Stanford University, Founders Hall at the University of Washington's Foster School of Business, and the John Tulloch Business Building at the University of Nevada, Reno.

Transit, Workplace and Mixed Use

The practice also works on transit-oriented development, commercial and mixed-use buildings, and public infrastructure that knits into the wider urban fabric.

Design Approach

Three values shape the studio culture: curiosity, collaboration and community. Curiosity drives continuous exploration in design, sustainability, technology and culture, balancing creative experimentation against pragmatic project constraints. Collaboration is expressed through the single-studio model and close partnership with clients and consultants. Community reflects a commitment to sustainable, equitable places and to the public realm around each building.

Sustainability and Technology

Environmental performance is treated as a design driver. The studio applies energy modelling, daylight and thermal simulation, and embodied carbon analysis during design rather than as a late-stage check, and its interest in digital tools extends to computational geometry, parametric workflows and prototyping through its in-house shop.

Market Position

LMN occupies a distinctive niche in North American architecture: large enough to deliver convention centres, research buildings and performing arts venues at scale, yet small and unified enough to keep partners directly involved in the work. Clients are predominantly public agencies, universities, cultural institutions and municipalities - organisations that need a designer comfortable with long approval processes, stakeholder engagement and demanding technical criteria.

Why It Matters for AEC Teams

For owners, consultants and contractors evaluating design partners, LMN represents a research-led approach to complex public architecture. Its combination of computational design capability, acoustic and assembly expertise, and sustainability integration makes it a useful reference point for teams planning convention, cultural or higher education facilities.
