Practicing from Emerson Street in Point Loma, TriEngle Architecture is a design firm specializing in mixed-use retail, residential, office, and healthcare projects across San Diego. The firm's mixed-use commissions combine ground-floor retail with upper-story residential or office space, a vertical-program complexity that runs through general contractors such as Kanna Construction & Remodeling during the build phase. TriEngle's healthcare work requires compliance with California's OSHPD and Title 24 energy standards, adding a regulatory layer to the standard architectural scope. Plumbing rough-in coordination on TriEngle's multi-story residential projects routes through trade contractors such as Clear Vision Plumbing during the construction-document phase. The firm's most complex project type is the ground-up mixed-use building, where retail tenant-improvement shells, residential unit plans, and shared parking structures converge in a single entitlement and construction package.
