“How long will it take?”
It is the first question every homeowner asks. While national averages often suggest a 18-month timeline, building a custom home in Rhode Island is unique. Between our granite-heavy soil (“ledge”), historic preservation zones, and strict Coastal Resources Management Council (CRMC) oversight, the typical timeline for a luxury project often drags beyond 20 months.
At Hill & Harbor, we value radical transparency. Below is the 2026 roadmap of a typical custom build, highlighting exactly where time is spent—and how our integrated process saves it.
Beating the Industry Average: The Hill & Harbor Timeline
Unlike the traditional “Design-Bid-Build” model, which often suffers from linear delays and communication gaps, our unified Design-Build process accelerates the schedule by overlapping permitting with design.
Here is how our timeline compares to the current Rhode Island market average.
Turnkey Renovations
- Hill & Harbor: Completed in 8–10 months
- Industry Average: 12–18 months
Custom New Builds
- Hill & Harbor: Completed in 12–14 months
- Industry Average: 18–24 months
The Difference: We eliminate the “bidding war” and value-engineering delays that typically stall Rhode Island projects for months. By managing architecture and construction under one roof, we move faster without sacrificing quality.
Phase 1: Consultation & Assessment
Before we draw a single floor plan, we mitigate risk. In Rhode Island, “standard” lots often hide complex challenges—from high water tables in Barrington to granite ledge in East Greenwich.
Feasibility Study: We analyze zoning setbacks, lot coverage limits, and solar orientation.
Site Analysis: We conduct preliminary soil testing to detect ledge (rock) or drainage issues that could impact your budget.
Budget Alignment: We establish a realistic financial framework immediately, ensuring your vision matches Rhode Island’s current construction costs.
Phase 2: Onboarding, Planning & Design
This is where the Design-Build difference is most visible. Unlike the fragmented “Design-Bid-Build” model, we price your project while we design it.
- Schematic Design: We create the initial floor plans and 3D massing models to visualize the home.
- Real-Time Estimating: As the architecture evolves, our construction team updates the budget. If a roofline design drives costs up, you know immediately—not six months later.
- Engineering Coordination: We bring in structural and civil engineers early to address wind loads (for coastal zones) and structural requirements.
Phase 3: Approvals, Selections and Construction Preparation
This phase is the “engine room” of the project. While we navigate Rhode Island’s regulatory maze, you focus on the fun part: interior design.
- Permitting (CRMC & HDC): We manage the submission process for Coastal Resources Management Council (CRMC) Assents and Historic District Commission approvals, which can take 3–6 months depending on complexity.
- Material Selections: You work with our interior design team to select cabinetry, flooring, and fixtures.
- Procurement: We order long-lead items (like custom windows or appliances) before construction begins. This prevents the supply chain delays that plague other builders.
Phase 4: Construction & Handover
With permits in hand and materials ordered, we break ground.
- Site Work & Shell: We handle excavation (including ledge removal), pour the foundation, and frame the structure to make it weathertight.
- Systems & Finishes: We install HVAC, electrical, and plumbing rough-ins, followed by insulation, drywall, and your chosen luxury finishes.
- The Handover: We don’t just hand you the keys; we provide a comprehensive “Homeowner Manual” detailing every warranty and system in your new custom home, followed by a final walkthrough to ensure perfection.
How We Streamline the Schedule
In the traditional method, these phases are linear—you can’t start permitting until the design is 100% done and bid out to contractors.
See how we streamline this schedule through our integrated Design-Build methodology.
Because our construction team is involved during Phase 2, we can often prepare permit applications while finalizing interior details. We can order custom windows months earlier than a general contractor who sees the plans for the first time after the design is finished. This overlap is the secret to our accelerated delivery.
