Our Mission
Costello & Co was born from big dreams, real budgets & the wild idea that luxury design shouldn’t be out of reach. What started as a side hustle quickly turned into a full blown obsession: creating homes that are high-end but feel totally you. We mix soul with style & make sure your space tells your story.
Our Values
Costello & Craft | We’re passionate about transforming outdated homes into inspiring spaces, all while honoring the character that makes each one unique. We see every renovation as a chance to blend timeless design with the personal stories of the people who live there. And yes, we geek out over trim & grout colors. We’re obsessed with the little details. If it’s not thoughtful, it’s not happening.
Costello & Connection | Your home is more than just a project, it’s a reflection of you. We collaborate closely with each client to understand your vision, values, & lifestyle, creating spaces that feel deeply personal & built to last. We’re not here to bulldoze your vision (or your kitchen… unless you ask us to). We listen. We ask a lot of questions. We want to know how you live, what drives you crazy about your current space, & what makes you feel most at home.
Costello & Value | We love a splurge & a steal. Whether it’s a show-stopping range or a clever hack, we’re all about smart design that works hard & makes sense. To us, smart design also means smart investment. We’re cost-conscious, transparent with budgets, & focused on delivering quality without the unnecessary extras.
Costello & Community | Metro Detroit isn’t just where we work...it’s where we live, raise our families, & (painfully) cheer for the Lions. We’re proud to leave our mark here, one home, one neighborhood, one family at a time. Because beautiful spaces have the power to uplift communities & enrich everyday life.
Costello & Commitment | From the first “what if?” to the final “holy crap, we did it!” We’re here to guide, support, & deliver with honesty, transparency, and pride. We’re deeply invested in good work...for your space and your sanity.
