Workshop 315

What Workshop 315 does

Workshop 315 is a private architecture firm co-founded in 2019 by Matthew Hagen and Ryan Adanalian, headquartered in Seattle, Washington with a second operating base in Leadville, Colorado. The firm provides architectural design services for residential and small commercial projects, encompassing new construction, remodels, additions, ADUs/DADUs, second-story additions, basement remodels, and tenant improvements. A separate Feasibility Studies product line serves prospective home buyers in Seattle seeking to understand the development potential of neighborhood residential lots, with both Quick and Detailed (field-verified) tiers available. The firm's technical specialization centers on sustainable and natural building methods, including Net Zero Energy design, Passive House Principles, Living Building Challenge Principles, Straw Bale, Rammed Earth, Timber Frame, Hempcrete, and healthy materials selection; Ryan Adanalian holds Living Future Accreditation, Permaculture Design Certification, and Passive House Training credentials. The firm is an AIA member firm at both Seattle and National levels and maintains active involvement in sustainability organizations including the International Living Future Institute, Northwest Eco Building Guild, and Natural Building Alliance.

The firm generates revenue through project-based professional services fees, with pricing determined by project scope and complexity on a custom quote basis. Its go-to-market is sales-led and direct, relying on a portfolio-driven website, email contact forms, and referrals within the regional residential and small-commercial owner communities. Customer segments include residential homeowners seeking design for new homes, expansions, and remodels; small commercial businesses requiring tenant improvements such as restaurants, coffee shops, retail spaces, and veterinary clinics; and Seattle-area prospective home buyers commissioning pre-purchase feasibility analysis. Documented engagements span Seattle, Lake Stevens, Newport Beach (California), Oak Creek (Colorado), and other U.S. locations, with the firm's stated geographic reach described as "Pacific Northwest and beyond."

Business operations are carried out entirely by the two co-founders, with no evidence of additional staff, external investment, or venture funding. The ownership structure is an equal partnership between Matthew Hagen (AIA, based in Seattle) and Ryan Adanalian (LFA, PDC, based in Leadville), both of whom personally lead projects and represent the firm. The company's name combines "Workshop" — reflecting the co-founders' collaborative learning approach — with "315," the compass bearing for northwest (NW), honoring the firm's Pacific Northwest roots. Notable completed projects include the Dynasty Room (Best Bar in Seattle 2018), Ada's Technical Books & Café, Blue Ridge Coffee House, Frontier Village Veterinary Clinic tenant improvement, and multiple residential remodels including an Arbor Heights project that achieved Built Green Emerald Star Certification.
