Precision architectural design and general contracting under one unified vision in Oregon and Washington.
Established in 2005, Method Design Construction is an Oregon and Washington-based design-build firm specializing in architectural design, general contracting, and comprehensive construction management.
Larry R. Cowlishaw is the founder, architectural designer, and general contractor of Method Design Construction. His journey began with a custom design he created in high school, sparking a lifelong passion for architecture and structural engineering that has driven the firm for over two decades.
Whether creating custom in-house architectural concepts or collaborating with specialized licensed architects on complex structural developments, our core mission is simple: turning client ideas into code-compliant, high-performance physical realities.
From initial concept consultation to structural handover, Method manages the full spectrum of residential and commercial property development across the Pacific Northwest:
In-house architectural drawing, accessory dwelling unit (ADU) engineering, and complete ground-up custom home builds.
High-end interior transformations, structural wall modifications, luxury kitchen and bath gut-renovations.
Fire damage reconstruction, commercial tenant turnover, seismic retrofitting, and municipal code compliance.
You bring us your ideas, and we craft tailored architectural blueprints designed for maximum space efficiency, aesthetic luxury, and natural lighting.
We leverage rigorous project management principles to develop a granular scope of work and a detailed cost breakdown, delivering fixed commitments with no surprise markups.
We specialize in acquiring and developing challenging, hard-to-build urban lots in the Portland Metro area — handling steep slope engineering, geotechnical analysis, and environmental overlays.
We actively help property owners capture PDC programs, tax abatements, System Development Charge (SDC) exemptions, and mortgage credit certificates to maximize asset ROI.
Partnered with Energy Trust of Oregon and Earth Advantage, we integrate high-efficiency heat pumps, eco-friendly insulation, and sustainable building systems wherever economically viable.
We maintain a steadfast commitment to supplier diversity by employing licensed, highly skilled trade specialists from local minority-owned subcontractors for roofing, drywall, masonry, and mechanicals.
