Whitten Architects

What Whitten Architects does

Whitten Architects is a Portland, Maine-based residential architecture firm founded in 1986 by Rob Whitten. The firm designs custom homes, coastal residences, renovations, and multi-generational living spaces across New England, with a stated design philosophy rooted in biophilic principles, site-specific response to the natural landscape, and New England vernacular traditions. Service offerings span full custom residential architecture, coastal home design, and a documented design methodology covering sustainability, regional design, site-specific design, and multiple project typologies; the firm's portfolio includes award-recognized projects such as Falls Pasture (Maine), Salt Marsh (New Hampshire), Meadow Cove, Cole Farm Residence, and several coastal retreats.

The firm operates as a bespoke professional services practice with 1–10 employees, delivering work through direct client engagement rather than transactional channels. Revenue is generated on a project-by-project basis typical of professional services, with pricing not publicly disclosed and engagements scoped to client requirements. The firm maintains a multi-channel digital presence (website, Instagram, Facebook, LinkedIn, Pinterest, Houzz, email newsletter) and supplements reputation-led lead generation with PR distribution and industry recognition, including multiple AIA Maine Design Awards in 2024 and 2025. No funding events, parent company, acquisitions, or AI/ML capabilities are disclosed; the business is founder-led and privately held.
