Oakland County's Women-Owned Design-Build Firm
Costello & Co Construction is a licensed, women-owned design-build firm headquartered in Birmingham, Michigan — serving homeowners throughout Oakland County and Metro Detroit who are ready to transform their kitchens, bathrooms, and living spaces into something they love coming home to.
We're not a large regional contractor that treats your project like a number. We're a focused, detail-driven team that handles everything from initial concept through final construction — design, permitting, material selection, and build — all under one roof. That means one point of contact, one cohesive vision, and a process that's transparent from the first conversation to the final walkthrough.
Our Remodeling Services
We specialize in the spaces that matter most to Oakland County homeowners:
Bathroom Renovations
Primary suite overhauls, guest bath refreshes, powder room redesigns, and spa-inspired master bathrooms with custom tile, stone, and handcrafted finishes.
Whole-Home Transformations
Multi-room renovations coordinated under one plan, one team, and one seamless process — so your home feels intentional throughout.
Home Additions
Kitchen expansions, primary suite additions, mudrooms, and second-story additions designed to integrate naturally with your existing home.
Kitchen Remodeling
Custom cabinetry, layout redesign, island additions, luxury countertops, and full kitchen transformations built around how your family actually lives.
Accessible Design & Build
Sensory-friendly layouts, curbless showers, and accessible upgrades that make your home work for every member of your household without sacrificing design.
Basement Finishings
Convert unfinished space into home offices, gyms, guest suites, entertainment rooms, and additional bathrooms that add real square footage and equity.
Fireplace & Plaster
Custom microcement finishes, limewash walls, venetian plaster, and fireplace redesigns that bring depth, warmth, and artistry to any space.
