As families grow and needs change, many homeowners find that their current home no longer provides enough space. A thoughtfully designed addition allows you to expand your home without leaving the neighborhood you love. At J. McSharry & Sons, we specialize in home additions in South Shore MA that increase square footage while preserving the character and architectural integrity of the existing home. With decades of construction and remodeling experience, we carefully integrate each new space so it feels like a natural part of the original structure.
Whether you are adding a family room, expanding a kitchen, building an in-law suite, or creating additional bedrooms, we approach every project with careful planning and skilled craftsmanship. The result is a well-designed addition that gives you more room for everyday life while supporting the long-term value of your home.

Home additions can serve a wide range of purposes depending on your needs and property layout. Some of the most common additions we design and build include:
Create a larger, more comfortable gathering space for everyday living, entertaining, and spending time together.
Add the space needed for improved storage, functionality, seating, and movement throughout the kitchen.
Create a private bedroom and bathroom suite designed around your comfort, storage needs, and daily routine.
Build comfortable, independent living accommodations for extended family members or long-term guests.
Increase your home’s square footage while preserving more of the existing yard and property footprint.
Add practical living space to accommodate a growing family, frequent guests, or changing household needs.
Create a bright, inviting space that brings in more natural light and provides a comfortable connection to the outdoors.
Create a self-contained living space with its own kitchen, bathroom, and entrance for extended family, guests, or flexible long-term use.
Our simple, five-step process keeps your home addition organized, coordinated, and easy to navigate from the initial consultation through project completion.
We begin by discussing your goals, evaluating the existing home, and reviewing the proposed scope, budget considerations, and timeline expectations.
We work with each customer to plan the layout and finalize architectural details, materials, finishes, and structural requirements so the addition complements your home and supports the way you plan to use the space.
Before construction begins, we coordinate permits, establish the project schedule, and organize the trades and materials needed to keep the work progressing efficiently.
Our experienced team completes the foundation, framing, exterior work, mechanical systems, and interior finishes with careful attention to quality, detail, and your property.
Once construction is complete, we walk through the finished addition with you, review the work, and confirm that every detail meets expectations before project closeout.
From new home construction and thoughtfully designed additions to transformative renovations, we bring the craftsmanship and care local families have trusted for decades.
From the first conversation to the final walkthrough, we’re committed to exceeding expectations every step of the way.
