What Juniper Design+Build does
Juniper Design+Build is a privately held, majority women-owned design-build firm headquartered in Portland, Maine, specializing in custom residential construction and major renovations for affluent homeowners in coastal Maine communities including Cape Elizabeth and Peaks Island. The firm was formed through the merger of three founders' prior businesses — Thompson Johnson Woodworks (Heather Thompson, now General Manager), Rachel Conly Design (Rachel Conly, now Design Director), and the production expertise of Mark Pollard (Production Director) — uniting in-house architectural design with carpentry and project execution under a single integrated delivery model. Its core offering is end-to-end custom home design and construction, including deep energy retrofits of historic homes and accessory structures such as studios and bunkhouses.
The firm's technical differentiator is high-performance green construction built around Passivhaus air-sealing standards, advanced thermal envelope practices (thermally decoupled walls, triple-glaze windows, rain screen siding systems), and low-carbon material selection including locally sourced cedar, rift-sawn white oak, and concrete-reducing foundation designs. Documented technical outcomes include the Foursquare project achieving 1.0 ACH50 (exceeding Passivhaus thresholds) heated by two heat pumps, and the Evergreen House winning Fine Homebuilding's 2020 Best New Home of the Year. The integrated design process brings the client, in-house designer, builder, engineer, and trade subcontractors onto the project from inception, eliminating the architect-to-builder handoff friction typical of traditional residential delivery.
Juniper operates a direct-to-consumer, sales-led go-to-market model with no intermediaries: homeowners contact the firm via website, phone, or email for initial consultations, and each project is custom-quoted based on scope, materials, and design complexity with no publicly disclosed pricing. Distribution is entirely regional within coastal Maine, supported by an organic marketing mix consisting of a Squarespace project gallery, an active Instagram presence, Facebook/LinkedIn/Pinterest accounts, community Q&A events ("Bewildered? Ask a Builder!"), cultural sponsorships (Portland Bach Experience, Classical Uprise), and earned media in Fine Homebuilding, Dwell, Journal of Light Construction, and Maine Home + Design. Revenue is project-based, one-time per engagement, with no recurring contracts or subscription model.
