Designed for Your Property

A successful ADU or home addition should improve your property without feeling disconnected from the existing structure. At Mr Build Co., we begin by understanding how you plan to use the new space, what your site can accommodate, and which architectural details will create a natural, cohesive appearance.

Your project may include a detached ADU, attached living suite, garage conversion, expanded kitchen, new bedroom, additional bathroom, second-story addition, or flexible space for work and guests. We carefully consider access, privacy, circulation, windows, storage, utilities, and connections to outdoor areas.

Backed by more than 40 years of construction experience, our team coordinates each phase with care. We help turn underused areas into comfortable, practical spaces that support changing family needs, increase functionality, and add meaningful long-term value to your home today.

Building an ADU or expanding a home is a major investment, which is why our team focuses on organization, craftsmanship, and coordination from the first consultation through completion.

We manage each stage of construction, including preparation, foundation work, framing, roofing, plumbing, electrical systems, insulation, drywall, flooring, cabinetry, painting, and finishing details. Our structured process helps maintain progress, reduce uncertainty, and keep homeowners informed as the new space takes shape.

We also pay close attention to cleanliness, safety, scheduling, and respect for your property. With Mr Build Co., you gain a thoughtfully planned addition built to provide comfort, flexibility, lasting performance, and greater value over time.
