Design-Build Services
We specialize in complex residential projects that demand a seamless integration of building design and advanced building science.
Design
Design and Engineering in association with South County Design Group Inc. We work directly with our clients through a collaborative design process, developing floor plans, elevations, and 3D views using Chief Architect and producing detailed construction documentation in AutoCAD.
- 3D modeling — AutoCAD
- 3D modeling — Chief Architect
Building Science
Building science is integral to every project. We design the thermal envelope, air barrier systems, and mechanical systems as an integrated whole — optimizing performance, comfort, and energy efficiency for coastal Rhode Island conditions.
- Energy Modeling — Right-SUITE Universal by MiTek
- Thermal Envelope — High-R Enclosure Performance, Continuous Exterior Insulation
- Air Barrier Systems — Continuous Interior & Exterior Sealing
- Vapor Drive Management — Smart Vapor Retarders
- Balanced Ventilation — Dedicated ERV Systems
- Thermal Comfort — Uniform Surface Temperatures, Convection & Draft Elimination
- Net Zero & Energy Resilience — DOE Efficient New Homes, Proprietary System Optimization, PV & Battery Storage Integration
Permitting
Coastal construction in Rhode Island involves a complex web of regulatory agencies. We manage the entire permitting process before the design begins — ensuring your project adheres to all requirements.
- CRMC (Coastal Resources Management Council) — Assents & Buffer Zone Management
- RIDEM (Dept. of Environmental Management) — OWTS (Septic) & Freshwater Wetlands
- Local & State Building Permits
- Building Code Compliance
- Zoning Board of Review — Variances & Special Use Permits
Construction
The professionals who design the project directly oversee its construction. We employ our own team of carpenters and manage execution on-site daily, from foundation through finish.
- New Construction — High-Performance & Net Zero Homes
- Custom Renovations — Whole-Home Structural & Energy Retrofits
- Building Enclosure — High-Performance Assembly Execution
- Project Delivery — Integrated Design-Build Services
Site Planning
Before design begins, we conduct the research and analysis to determine the allowable footprint and regulatory requirements for your site.
- CRMC (Coastal Resources Management Council) — Assents & Buffer Zone Management
- FEMA Flood Zone Compliance — V-Zone & Coastal A-Zone Requirements
- RIDEM (Dept. of Environmental Management) — OWTS (Septic) & Freshwater Wetlands
- Local & State Building Permits — Zoning Analysis
Coastal Construction
Coastal Rhode Island demands construction that withstands hurricanes, storm surge, and demanding environmental conditions. We build to meet or exceed current flood zone and high-wind requirements.
- FEMA Compliance — High Hazard V-Zone Requirements
- Flood Zone Design — Coastal A & AE-Zone
- Structural Resiliency — Elevated Pile & Pier Foundations
- High-Wind Systems — Hurricane-Resistant Building Enclosures
Property Management
Property management services are provided through Sand Hill Estate Partners.

Where We Build
Service Areas
NJ&J Builders works across coastal Rhode Island — each town has its own permitting, flood, and zoning environment, and our integrated design-build approach is built around that reality.
