What SUM Design Studio + architecture does
SUM Design Studio + architecture is a Portland, Oregon-based, full-service architecture and interior design firm founded in 2006, operating as a private partnership led by principals Matt Loosemore and Eric Hoffman with a 14-person team. The firm delivers commercial, multifamily residential, financial institution, hospitality, healthcare, educational, and single-family residential design, with particular depth in adaptive reuse of historic structures, sustainable design using natural materials, and Pacific Northwest regional aesthetics. Notable technical capabilities include multi-location branch design prototyping for credit unions and banks, cross-laminated timber (CLT) and glulam construction for coastal climate resilience, and empathy-driven pediatric and wellness facility design.
The firm generates revenue through project-based professional service fees, with no public fee schedules and quotes provided on a per-project basis scoped to complexity, square footage, and timeline. Its go-to-market is direct, relationship-driven B2B sales targeting enterprise and mid-market clients across the Pacific Northwest, with one documented project in Austin, Texas. The firm is supported by long-standing co-development partnerships with Momentum (brand and strategy for financial institution rollouts) and Cobalt (master planning for multifamily developments), and engages local architect-of-record partners such as Noack Little for out-of-region delivery. Recurring enterprise clients include Rivermark Community Credit Union (decade-plus, five-plus branches), First Federal Savings & Loan (multiple Washington branches plus a 35,000 sq ft headquarters), Brave Care (multi-location pediatric clinics), and Verity Credit Union. Marketing is conducted primarily through a portfolio website, project case studies, and earned media features, including a Dwell magazine placement for the L1 Residence.
