As your needs evolve, your home should too. Whether you’re adding a second-story master suite, building a detached garage, or creating a private ADU for family or rental income, Kellogg Construction designs and builds seamless additions that blend beautifully with your existing structure. We handle everything from zoning analysis and architectural planning to foundations, framing, and finishes—delivering turnkey expansion solutions with zero guesswork. Our approach ensures that every addition enhances both the look and function of your home while maximizing space and property value. Detached garages and ADUs are also a smart way to increase usable square footage without altering the main home footprint, and we’re experienced in navigating Massachusetts zoning and permitting for these types of builds. Whether your goal is storage, workspace, rental income, or multigenerational living, we deliver solutions tailored to your property and lifestyle.
