Whole Home Renovation in Oakland County, Michigan
Costello & Co Construction is a licensed, women-owned design-build firm specializing in whole home renovations throughout Oakland County, Michigan. We help homeowners transform the spaces they use most — kitchens, bathrooms, basements, first floors, and entire levels — into homes that feel more functional, more beautiful, and more aligned with how they actually live.
As a design-build firm based in Birmingham, we manage every phase of your home renovation under one roof: design, material selection, permitting, and construction. That means one team, one point of contact, and a process that stays coordinated from your first conversation to your final walkthrough. No handoffs between a designer and a contractor. No communication gaps. Just a smooth renovation and a result you're genuinely proud of.
A whole home renovation doesn't have to mean remodeling every square foot. For some Oakland County homeowners, it means reconfiguring a first floor for better flow. For others, it's refreshing an upstairs with updated bathrooms, finishing a basement into real living space, or building an addition that finally gives the family room to breathe. We tailor every project to your goals, your budget, and the way you want your home to feel.
Why Invest in a Whole Home Renovation
A well-planned home renovation can completely change how your home functions — without the disruption and cost of moving. Whether your layout feels outdated, your family has outgrown the space, or you simply want your home to feel more like you, strategic renovations make a lasting impact on daily life and long-term property value.
Oakland County homeowners who invest in whole home renovations consistently tell us the same thing: they wish they'd done it sooner. Improved flow between rooms, more usable living space, modernized finishes and fixtures, custom storage solutions, and finished square footage that was previously going to waste — these changes compound in ways that go far beyond aesthetics. They change how your mornings feel, how your family gathers, and how much you love coming home.
Our Whole Home Remodeling Services
First Floor Renovations
We reconfigure Oakland County kitchens, living rooms, dining rooms, mudrooms, laundry rooms, and powder baths for better flow and functionality. First floor renovations are some of our most transformative projects — opening walls, improving sight lines, and creating spaces that feel connected and intentional throughout.
Second Floor & Bedroom Refresh
We refresh bedrooms, update bathrooms, improve storage, and modernize finishes on upper levels throughout Oakland County homes. Whether it's a primary suite overhaul, a kids' bathroom renovation, or a full upstairs refresh, we coordinate every trade and every finish to deliver a cohesive result.
Basement Finishings & Lower Level Remodels
We transform unfinished or underutilized basements into purposeful living space — home gyms, offices, guest suites, entertainment rooms, playrooms, and additional bathrooms. Oakland County homes often have generous lower levels with real potential, and we help homeowners unlock that square footage in ways that add genuine long-term equity.
Home Additions & Expanded Living Space
When you need more room but love your neighborhood, a thoughtfully designed addition is the answer. We design and build kitchen expansions, primary suite additions, mudrooms, sunrooms, and second-story additions throughout Oakland County that integrate naturally with your existing home's architecture and scale.
Custom Built-Ins & Millwork
We design and install custom cabinetry, built-in shelving, window seats, mudroom storage systems, and architectural millwork throughout Oakland County homes. These custom storage solutions make every inch of a space work harder while adding character and value that off-the-shelf furniture simply can't match.
Full Renovation Planning & Constructions
For Oakland County homeowners ready for a comprehensive multi-room renovation, we manage the entire project from design through construction — coordinating every trade, every delivery, and every decision so your renovation runs on schedule and on budget. You'll always know what's happening and what's next.
Our Whole Home Renovation Process
Every Costello & Co renovation begins with a discovery conversation. We want to understand how your household uses your home before we start redesigning it — because the best renovation plans start with listening, not drawing.
From there, we move through five phases:
-
Consultation & Vision Planning — We meet in your home, assess the space, and develop a clear understanding of your goals, priorities, and budget range.
-
Design & Material Selections — Our design team develops plans and renderings and walks you through every material selection, from cabinetry and tile to fixtures and finishes. Nothing moves forward until you love it.
-
Project Scope & Scheduling — We finalize a detailed scope of work, timeline, and contract so you know exactly what's included, what it costs, and when it happens.
-
Construction & Project Management — Our team manages every phase of construction, coordinating trades and deliveries and keeping you updated throughout. We treat your home with the care and respect it deserves.
-
Final Walkthrough & Completion — We walk through every inch of the finished project together to make sure everything meets your expectations before we call it done.

Frequently Asked Questions
What is considered a whole home renovation?
A whole home renovation doesn’t always mean remodeling your entire house. It can include updating multiple connected spaces, such as a kitchen and first floor, upstairs bedrooms and bathrooms, a basement finish, or an addition — all tailored to your goals.
How much does a whole home renovation cost in Oakland County?
Costs vary based on the size of the project, scope of work, and materials selected. We provide detailed estimates based on your home, goals, and priorities.
How long does a whole home renovation take in Oakland County?
Timeline varies significantly based on scope. A focused first-floor renovation might take 8–12 weeks. A multi-level whole home renovation including a basement finish and addition could run 4–6 months. We develop a detailed project schedule during the planning phase so you know exactly what to expect before construction begins.
Do you handle permits for whole home renovations in Oakland County?
Yes — permit management is included in our design-build process. We handle all required permits through Oakland County and the relevant municipalities, coordinate inspections, and ensure your renovation is fully code-compliant from start to finish. This is one of the significant advantages of working with a design-build firm rather than managing a designer and contractor separately.
Can you renovate in phases?
Yes — many homeowners choose to renovate in phases. We can help prioritize spaces and create a plan that aligns with your budget and timeline.
Do you help with design and layout planning?
Yes — as a design-build firm, we manage both design and construction. This allows us to create thoughtful layouts and cohesive finishes from start to finish.
Can you finish basements and add living space?
Absolutely. We frequently finish basements, rework underused spaces, and build additions to help homeowners make the most of their homes.

We serve homeowners throughout Oakland County, including Birmingham, Bloomfield Hills, Royal Oak, Troy, and surrounding communities.
