Home Additions & ADUs in Massachusetts & Rhode Island

Additions and ADUs involve more variables than most remodeling projects. Stanek
Construction provides custom home additions and accessory dwelling units (ADUs) for
homeowners throughout Rhode Island and Massachusetts. Our design-build approach
means you can expect clear communication, detailed planning, and experienced
oversight to guide your project from concept through completion.

Design Your Home Addition

A successful home addition should feel like it was always meant to be there. Our design process focuses on how new spaces connect to your home, both structurally and visually. Whether you’re adding living space, accommodating extended family, or creating a separate ADU, we design additions that respect your home’s architecture, flow naturally with existing layouts, and meet all local zoning and building requirements.

Our Design-Build Process for Additions & ADUs

Home expansions require coordination across design, engineering, permitting, and construction. Our design-build process keeps every phase aligned, reducing delays and ensuring clear accountability

01 Design, Planning & Feasibility

We begin by evaluating your property, goals, and local regulations. Our team develops design concepts that consider structure, layout, access, and future use to ensure your addition or ADU is both practical and compliant before construction begins.

02 Permitting & Pre-Construction Coordination

Before breaking ground, we handle zoning approvals, permitting, budgeting, and scheduling. This preparation phase is critical for additions and ADUs, where regulatory and structural details can significantly impact timelines

03 Construction & Integration

This is the phase where careful planning pays off. Construction begins as we coordinate framing, utilities, and finishes to naturally blend the new space with the rest of your home. Throughout the build, we oversee quality and progress to keep everything aligned with the original plan.
