Thoughtfully Designed Home Additions in Greater Boston, MA
Designed for the Way You Live
Expertly Planned Home Additions
A home should grow with you.
When your space no longer supports the way you live, whether that means room to gather, space to focus, or simply the ability to breathe a little easier, it is often not about leaving your home behind. It is about reimagining what it can become.
A thoughtfully designed home addition creates that opportunity.
Not just more square footage, but a more natural way of living.
At Lee Kimball, every addition begins with understanding how you want your home to feel. From expanded kitchens and family spaces to private primary suites, second-story additions, and dedicated workspaces, each project is designed to feel intentional and complete, as though it has always belonged.
DESIGNED TO FEEL SEAMLESS
Throughout Greater Boston, homes carry character, history, and complexity. Expanding them requires more than adding space. It requires careful consideration of how everything connects.
A successful home addition is one that feels whole.
That means aligning rooflines, respecting architectural details, and ensuring the transition between old and new feels effortless. It means thinking through structure, light, and flow so that each space works together naturally.
The result is not an addition that stands apart, but one that belongs.
BUILT WITH CARE. DESIGNED TO LAST.
For more than 85 years, Lee Kimball has worked with homeowners throughout Greater Boston to transform how they live in their homes.
That legacy is reflected in every addition we create through craftsmanship, thoughtful design, and a commitment to doing things the right way.
No shortcuts.
No compromises.
Just spaces designed to stand the test of time.
