About Us

Costello & Co Construction is a women-owned design-build firm headquartered in Birmingham, Michigan — specializing in kitchen remodeling, bathroom renovations, whole-home transformations, and custom plaster and microcement finishes throughout Oakland County and Metro Detroit. Founded by Michelle Costello, the firm brings a perspective most remodeling contractors simply don't have. With a background in real estate, investment property flipping, and rentals, Michelle approaches every project through both a design lens and a financial one — creating spaces that are beautiful to live in and smart to own. "I think about resale value and ROI on every project," she says. "Whether a client is renovating their forever home or preparing a property for market, protecting their investment is always part of the conversation." Costello & Co is also one of the only design-build firms in Oakland County offering accessible and intentional design informed by Applied Behavior Analysis — creating sensory-friendly, aging-in-place, and behavior-informed spaces for families navigating autism, developmental differences, and accessibility needs. Designed with intention. Built with integrity. Every time.
