Our End-to-End Process

From your free consultation to keys-in-hand delivery, our integrated design-build process aligns architecture, engineering, procurement, and construction under one roof, eliminating handoffs, reducing delays, and ensuring your net-zero targets are achieved with measurable performance outcomes.

Discovery & Free Consultation

We begin with a comprehensive, free consultation that clarifies your lifestyle needs, budget range, timeline, preferred aesthetics, and sustainability priorities, then outline a customized roadmap covering design milestones, permitting strategy, financing options, and expected energy outcomes for your specific climate zone.

Site Analysis & Feasibility

Our team evaluates solar access, wind patterns, seasonal shading, buildable envelope, utilities availability, topography, local codes, and ecological constraints, translating findings into actionable feasibility insights that inform massing, orientation, and envelope strategies to maximize comfort and minimize energy demand from day one.

Integrated Design Sprint

Architects, energy modelers, and structural and MEP engineers collaborate in fast design sprints, testing variations through parametric simulations to optimize daylight, envelope performance, mechanical sizing, and cost, delivering concept options with clear trade-offs, carbon impacts, and phased investment pathways.

Sustainable Design Principles

We apply rigorous passive design fundamentals first, then layer efficient systems and renewables, creating homes that remain comfortable during outages, drastically cut operational emissions, and prioritize healthy indoor air through low-toxicity materials and balanced, filtered, continuously supplied fresh air.

Architecture & Interior Experience

We craft spaces that feel generous, bright, and calming, using daylight, views, acoustics, and material warmth to shape daily rituals, while discreetly embedding performance layers so comfort, efficiency, and beauty coexist without compromise throughout every room and transition.

Flow, Zoning, and Storage

We design intuitive circulation that separates quiet and active zones, prioritizes sightlines, and integrates built-in storage to reduce clutter, enhancing calmness while maintaining flexibility for changing family needs, hobbies, remote work, and multigenerational living arrangements over decades.

Daylighting and Glare Control

Clerestory windows, light shelves, and carefully placed openings invite balanced daylight while controlling glare, with exterior shading and selective glazing coatings tuned to orientation and use, producing luminous, energy-efficient interiors that remain comfortable even on bright summer afternoons.

Biophilic Materials and Finishes

Natural wood, mineral plasters, and textured, low-emission finishes create tactile richness and visual calm, complementing plants and exterior views to reduce stress, improve well-being, and anchor the home’s identity in durable, timeless materials that age gracefully with everyday life.

Permitting, Codes, and Compliance

Our permitting specialists prepare complete, code-compliant packages, coordinate with authorities, and streamline submittals, addressing energy codes, structural, fire, and environmental requirements, so approvals proceed smoothly and construction begins on schedule with minimized surprises or costly redesigns.

Energy Code Documentation

We deliver detailed energy models, compliance reports, specifications, and product cut sheets demonstrating code alignment and performance targets, supporting accelerated reviews and clarifying how envelope, systems, and renewables interact to meet or exceed jurisdictional requirements for modern, efficient homes.

Environmental and Site Approvals

Stormwater plans, tree protection, erosion controls, and habitat considerations are integrated into documents and site practices, ensuring responsible construction that respects local ecosystems while satisfying municipal standards and protecting neighboring properties and public infrastructure during all project phases.

Coordination with Inspectors

We host pre-construction meetings, schedule phased inspections, and provide transparent field documentation, enabling inspectors to verify critical assemblies like air barriers and insulation continuity, minimizing rework and ensuring compliance is achieved efficiently without compromising quality or timelines.

Budgeting, Transparency, and Financing

We build trust with open-book cost models, value-engineer without sacrificing performance, and guide you through incentives and green financing, so your investment aligns with cash flow, long-term savings, and carbon goals from design through construction and operation.

Open-Book Cost Modeling

We share detailed line-item estimates with allowances, escalation assumptions, and contingency planning, updating scenarios as design evolves, so you can make informed trade-offs while maintaining performance, schedule, and budget accountability across the entire project lifecycle.

Schedule, Trades, and Procurement

We coordinate vetted trades, place long-lead orders early, and sequence work to protect critical assemblies, maintaining momentum while avoiding delays, with weekly updates that keep you informed and decisions moving at the right pace for quality and efficiency.

Airtightness, Insulation, and Detailing

Field teams implement robust air and moisture control details, verify insulation continuity, and protect penetrations, using checklists and photo documentation to ensure high-performance outcomes that translate directly into lower energy loads and quieter, more comfortable interiors.

Commissioning and Handover

We test systems, balance ventilation, confirm controls, and demonstrate operation to homeowners, providing manuals, warranties, and digital records, so you can confidently operate your home and maintain performance long after construction crews leave the site.

Resilience, Durability, and Risk Mitigation

We design for extreme weather, grid instability, and changing climate conditions, specifying assemblies, drainage strategies, and backup systems that preserve comfort, safety, and asset value during disruptions while minimizing maintenance and lifecycle costs over decades.

Materials, Embodied Carbon, and Supply Chain

We evaluate embodied carbon, durability, and sourcing ethics, prioritizing low-carbon assemblies and regional suppliers, then plan logistics to reduce waste, shorten lead times, and ensure responsible stewardship from procurement to installation and end-of-life considerations.

Low-Carbon Structure and Enclosure

We compare mass timber, advanced framing, and low-carbon concrete mixes, balancing structural performance, cost, and carbon impacts, while detailing assemblies for constructability, airtightness, and exceptional thermal performance without excessive material use or complexity.

Certified Wood and Prefabrication

FSC-certified timber and prefabricated components accelerate schedules, improve quality control, and reduce waste, with dimensional precision that supports tight envelopes and clean detailing, producing beautiful interiors with traceable, responsibly managed forestry sources.

Local Vendors and Circularity

We favor local manufacturers and recycled content where appropriate, establishing transparent chains of custody and reclaim pathways, minimizing transportation emissions and supporting community economies while delivering dependable quality and service responsiveness during construction.
