Expanding space, preserving soul.

Adding to your home is about more than extra square footage – it’s about extending the life and story of a place you already love – for your family, and for theirs.

At Mill Hill Builders, we design and build additions that feel like they’ve always belonged. Whether it’s a second story, a new wing, or an expanded kitchen or family room, our focus is on seamless integration – matching materials, proportions, and details so new and old come together naturally.

We collaborate closely with architects and homeowners to ensure every addition enhances both the form and function of the home. The result: spaces that feel generous, intentional, and perfectly aligned with how your family lives today.
