North River Architecture & Planning, PC

What North River Architecture & Planning, PC does

North River Architecture & Planning, PC is a vertically integrated design-build firm headquartered in Stone Ridge, New York, specializing exclusively in all-electric, net zero energy, Passive House-standard residential architecture and construction across the Hudson Valley region. Founded in the 1970s, the firm is owned and operated by three co-owners: Chris Ruel (Director of Architecture), Samantha Roesemann (Director of Operations), and Miles Dandrew (Director of Construction), supported by a team of approximately 13-14 individuals including architectural project managers, procurement, construction project management, and senior carpentry staff. Its core products are the Flexhouse system, a proprietary line of four semi-custom home plan templates (Flexhouse I through IV, ranging from 1,000 to 3,200 sq ft), fully custom Passive House design, deep energy retrofits of historic structures, and outbuildings (pool houses, guest houses, ADUs). All projects achieve airtightness below 0.6 ACH, triple-glazed European windows, mechanical heat recovery ventilation (minimum 75%), and rooftop solar to produce more energy annually than the home consumes.

The firm's business model combines a fixed-fee Phase I Feasibility Study (1-2 months), a fee-based Phase II Architectural/Engineering Drawings engagement leveraging Flexhouse templates (4-6 months), and a cost-plus Phase III Construction contract (approximately one year from mobilization). Approximately 85-90% of clients engage North River for the full integrated design-build experience, which the firm states eliminates the ~7% cost premium typically associated with net zero construction through process efficiencies. Optional PHIUS+ certification is available for an additional $7,000-$12,000, though roughly 75% of clients opt to reinvest those funds into the home itself. Revenue derives primarily from professional services fees on a project-by-project basis, supplemented by occasional direct land sales to design-build clients.

North River targets sustainability-motivated homeowners and prospective homeowners in 11 Hudson Valley counties (plus Bergen County, NJ and Berkshire County, MA) seeking primary residences, vacation homes, guest houses, and ADUs built to the highest energy performance standards. Distribution is direct-to-consumer, driven by a website-led content strategy, community workshops, Passive House Alliance Hudson Valley events, job site tours, the Electric House showroom and coworking space, and Airbnb stays at completed Flexhouse properties. A small commercial segment exists (notably the LEED Gold Eileen Fisher Creative Center), but residential remains the dominant vertical. The firm holds multiple PHIUS+ certifications (Accord, Gallatin, Kerhonkson, Overlook Mountain) and won the 2021 PHIUS Design Competition Single-Family category for the Gallatin Passive House.

Revenue model

1. Design-Build Project Revenue: North River generates the majority of revenue through integrated design-build contracts covering all three phases: Feasibility Study (fixed fee), Architectural/Engineering Drawings (fee based on customization from Flexhouse templates), and Construction (cost-plus construction contract). On 85–90% of projects, one team handles the full project from feasibility through construction completion. Construction is on a cost-plus basis with a fixed fee or percentage markup.
2. Design-Only Services: North River also provides architectural design services without construction, for clients who have their own trusted builder. Design fees are reduced when clients choose and customize a Flexhouse model, leveraging existing design templates. This is a smaller portion of revenue (~10–15% of projects).
3. Passive House Certification (optional add-on): Optional administrative process for clients who wish to have their home formally certified by the Passive House Institute (PHIUS). Certification costs range from $7,000 to $12,000 depending on project size. Approximately 75% of clients forgo certification, reinvesting those funds into the house itself.
4. Land Sales: North River occasionally offers parcels of land for sale directly to clients who wish to build with the firm. This is a supplementary revenue stream tied to the design-build process.
