Expertly Planned Home Additions
A home addition is an opportunity to expand not just your square footage, but the way you live. Whether you’re envisioning a new primary suite, an expanded kitchen and family room, a second-story addition, or a dedicated home office, the goal is to create space that feels natural and intentional. The most successful additions are those that feel as though they were always meant to be part of the home.
At Lee Kimball Design & Build, our integrated architecture, interior design, and construction teams work together from the beginning to ensure the new space complements your home’s character while supporting your lifestyle. Every detail, from layout and structure to finishes and exterior materials, is carefully considered to create a seamless result.
Seamless Integration Inside and Out
In the Greater Boston area, many homes have architectural history and structural complexity that require thoughtful planning. A well-designed addition must account for foundation work, rooflines, mechanical systems, and the visual connection between old and new. Our approach prioritizes structural integrity, energy performance, and cohesive design so the addition enhances both function and long-term value.
We carefully evaluate how the new space connects to existing rooms, ensuring improved flow and natural transitions. Exterior materials, trim details, and window placement are selected to maintain curb appeal and architectural harmony, resulting in an addition that feels cohesive rather than appended.
A Clear Process, from Concept to Completion
Expanding your home is a significant investment, and clarity throughout the process is essential. Our design-build model allows us to guide you from initial discovery and feasibility through architectural design, budgeting, and construction with one unified team. This collaborative approach minimizes surprises and ensures alignment between vision and investment.
From early planning conversations to the final walkthrough, we emphasize communication, craftsmanship, and attention to detail. The result is not simply more space, but a thoughtfully designed environment that supports how you live today and for years to come.

Our Home Addition Process
At Lee Kimball, we guide every project through a structured and transparent design-build process so you feel informed, supported, and excited from start to finish. With thoughtful planning, clear communication, and coordinated execution, we ensure your renovation experience is as rewarding as the final result.
1. In-Home Consultation: Our process begins with a personal conversation in your home. We listen closely to your goals, priorities, and vision for the space. This meeting helps us understand your needs, potential timeline, and budget considerations so we can tailor a plan that reflects your goals.
2. Conceptual Design: During conceptual design, we turn your ideas into visual plans. We explore multiple configurations, styles, and material options so you can compare approaches and get a clear sense of what’s possible. This step helps refine direction before detailed planning begins.
3. Design Development: Once a direction is chosen, we work with you to finalize design decisions, select all materials and finishes, and establish firm pricing. This meticulous phase ensures the project stays on schedule and aligned with your vision while minimizing surprises later.
4. Construction Agreement: Before construction begins, we prepare a comprehensive agreement outlining scope, deliverables, expenses, and timelines so everything is clear and agreed upon. This contract becomes the framework for all work to follow and gives you peace of mind.
5. Pre-Construction Planning: With the design finalized, our team prepares for the build. You’ll meet your construction team, review schedules and logistics, and receive access to an online client portal where you’ll find updates, photos, and project details. We coordinate permits, materials, and sequencing to ensure a smooth start.
6. Construction: Construction begins with thoughtful execution and regular communication. We walk through milestones with you — from demolition to finishes — and hold consistent site meetings to keep you informed. Our team treats your home with care and respect throughout the build.
7. Completion & Celebration: When work is complete, we do a thorough walk-through to ensure everything meets our standards and your expectations. Then it’s time to enjoy your transformed home. We follow up after completion and remain available for any future needs or questions.
