Concept and Massing

We translate your priorities into spatial diagrams and massing studies that explore orientation, privacy, and views, testing footprints and roof forms against setbacks and topography, ensuring the concept fits your site, budget, and long-term maintenance expectations before committing to detailed coordination and finishes.

Schematic to Construction Documents

Iterative schematic design evolves into coordinated construction documents, including plans, sections, elevations, details, and specifications, suitable for accurate pricing, expedited permitting, and efficient field execution, reducing RFIs through clarity, disciplined coordination, and robust integration between architecture, structure, mechanicals, and site utilities.

Energy Modeling and Codes

Early energy modeling and code analysis quantify enclosure performance, glazing ratios, and mechanical loads, enabling informed envelope decisions, HVAC sizing, and compliance pathways, supporting lower utility bills, comfort, durability, and eligibility for incentives without sacrificing architectural character, spatial quality, or daylighting strategies.

Interior Design and Finishes

Our interior team curates durable, beautiful finishes and fixtures aligned with your budget, lifestyle, and maintenance expectations, coordinating with cabinetry, lighting, and mechanical layouts so selections align with field realities, purchasing timelines, and performance standards for a cohesive, enduring interior environment.

Permitting and Approvals

We manage complex permitting workflows end-to-end, coordinating surveys, soils, engineering, and submittals, communicating proactively with jurisdictions, utilities, and HOAs to keep the process efficient and predictable while safeguarding compliance, neighborhood goodwill, and the project’s critical path for timely approvals.

Zoning and Variances

We review zoning constraints, overlays, and easements, proposing strategies for setbacks, height, floor area, and coverage, and when necessary prepare variance packages with narratives, diagrams, and neighbor outreach to demonstrate hardship, context sensitivity, and community benefits that merit responsible exceptions.

Sustainability and High-Performance

We design and build for comfort, durability, and efficiency, leveraging airtight envelopes, right-sized systems, healthy materials, and renewables to reduce operating costs and environmental impact without compromising aesthetics or budget, creating resilient, healthy homes that perform reliably year-round.

Budget transparency drives every decision, with open-book cost models, realistic allowances, and contingency management, plus introductions to lenders for construction loans, so you understand trade-offs clearly and confidence grows with each milestone as we track progress against your goals.

Transparent Cost Modeling

Our estimating team builds a detailed cost model early, itemizing scopes, allowances, escalation assumptions, and lead-time risks, updating live as design evolves, so you see the impact of each decision and can steer value without surprises or compromises to essential performance.

Allowances and Value Engineering

We establish realistic allowances for finishes and fixtures and propose targeted value engineering options that preserve design intent, evaluating lifecycle costs, warranties, and lead times to prevent false savings, procurement delays, and regrets that undermine quality or lived experience.

Construction Loan Support

We coordinate lender draw schedules, inspections, and documentation, aligning budget codes and invoicing with bank requirements to keep funds flowing smoothly, while our forecasting helps you avoid cash crunches during critical procurement windows and long-lead material commitments.

Document Sharing and Approvals

Centralized document management stores drawings, specifications, contracts, submittals, and change orders with version control and e-signatures, ensuring the field builds from current information and approvals are traceable, auditable, and fast for streamlined, transparent collaboration.

Progress Photos and Messaging

Field teams upload progress photos, videos, and daily logs, while threaded messaging captures decisions and clarifications, creating a transparent record that accelerates issue resolution, reduces unnecessary site visits, and preserves context for future maintenance and warranty.

Warranty and Post-Occupancy

We stand behind our work with clear warranties, structured service, and performance check-ins, ensuring your home functions as designed and small adjustments are addressed proactively as systems settle through the first seasons and changing weather conditions.

Comprehensive Warranty

Our warranty covers structural, systems, and workmanship scopes per contract, with defined response times and a dedicated service portal, so requests are tracked, scheduled, and resolved efficiently without repeating explanations or losing history between visits.

Maintenance Orientation

At handover, we provide manuals, filter schedules, finish care guides, and walk-through training, empowering you to maintain performance and appearance, while our reminders prompt timely tasks that extend equipment life and protect your investment.

Performance Tune-Ups

Seasonal tune-ups assess HVAC balance, door and window adjustments, humidity control, and water temperature settings, addressing comfort concerns and minor wear before they escalate, reinforcing reliability, safety, and long-term satisfaction with your new home.
