Garages, built properly
More than a place to park
A well-designed garage protects your cars, organizes everything else and adds curb appeal. A badly designed one looks bolted on. Keystone designs garages as architecture: rooflines, materials and proportions that match your house, with the structure, drainage and electrical capacity to handle workshops, EV chargers and storage.
We also go the other direction. If your family needs more room, converting an attached garage into a family room, office or bedroom suite can be one of the most efficient ways to add living space, when it's insulated, heated and finished to the same standard as the rest of the house.
What we build
Garage projects we build
New garages, bigger garages and garages turned into living space.
Detached garages
One-, two- and three-car garages designed to match the house, with proper foundations and drainage.
Attached garage additions
New or enlarged attached garages, connected through a mudroom where possible.
Carriage houses
Garages with finished space above for an office, studio or guest suite, including ADUs where zoning allows.
Garage conversions
Attached garages converted to family rooms, offices or bedrooms, with insulated floors, walls and ceilings and new heating and cooling.
Workshops
Dedicated circuits, lighting, ventilation and storage for woodworking or hobbies.
EV-ready garages
Electrical capacity and circuits planned for current and future electric-vehicle chargers.
Storage systems
Wall systems, overhead storage, cabinetry and epoxy or polished floors.
Signature looks
Three garages we love to build
The attached garage
Two or three bays tied into the house, with brick or siding and a roofline that matches, plus a mudroom entry.
The carriage house
A detached garage with a finished space upstairs for an office, studio or guest room, styled to match the main house.
The conversion
Turning an existing garage into living space, with an insulated floor, new windows and heating and cooling.

Louisville homes
Local rules that shape a garage
Where a garage can go and how it's built depends heavily on which city or HOA your home is in.
City rules
Hurstbourne requires garage additions to be attached to the house. Anchorage reviews accessory structures under its own zoning and, in the historic district, its Historic Preservation Commission. Prospect requires plans for garages and charges permit fees by square footage.
HOA requirements
Lake Forest requires at least a two-car garage on every lot, prohibits carports and expects brick or stone exteriors. Hunting Creek sections have their own architectural review. We prepare the submittals.
Older neighborhoods
In Crescent Hill and older St. Matthews, detached garages often sit at the rear of narrow lots or off alleys. Louisville Metro's Land Development Code governs their size and placement.
Design decisions
Getting a garage right
- Match the architecture. Roof pitch, overhangs, siding or brick, windows and trim matching the house.
- Size for real life. Room to open doors, walk around cars and store bikes, bins and tools, with deeper bays for today's SUVs.
- Foundations and drainage. Footings to Jefferson County frost depth, slabs sloped to drain, and grading that sends water away.
- Electrical capacity. Planned for EV charging, workshop tools, lighting and openers, often with a subpanel.
- Conversions done properly. Raised and insulated floors, insulated walls and ceilings, egress for bedrooms, new HVAC and a front elevation that no longer reads as a garage.
- Plan for ADUs. If you might want an apartment above later, we can frame and plumb for it now.
Planning your budget
What shapes the investment
- Attached or detached. Attached garages tie into the roof and walls of the house. Detached ones need their own foundation and utilities.
- Space above. A second floor for an office or apartment adds stairs, insulation, HVAC and plumbing, and may need zoning review.
- Exterior materials. Matching brick, stone or siding and adding dormers costs more than plain siding and is what makes it look original.
- Site work. Driveway changes, grading and tree removal are part of most garage projects.
- Approvals. Setbacks, lot coverage and accessory-structure rules vary by city, so we confirm them early.
We don't publish prices because every house is different. You get a fixed price at the end of design, before construction starts. Read the cost guide

Permits & approvals
Permits for garages and conversions
New garages and garage additions need building permits and must meet accessory-structure and setback rules (detached sheds under 200 square feet are exempt under the Kentucky Residential Code; garages generally aren't). Garage conversions need building, electrical and mechanical permits because they change use to living space. Small cities including Anchorage, Hurstbourne, Jeffersontown and Prospect add their own reviews, and Lake Forest's architectural committee must approve exterior changes.
The Keystone process
Six phases, no surprises
Each phase closes with your approval before the next begins, so the schedule, budget and selections are settled before construction starts.
Consultation
A walk through your home to understand how you live, what isn't working and what you want to change.
Design
Measured drawings and renderings, refined with you until the plan, the budget and the details agree.
Selections
Cabinetry, stone, tile, plumbing fixtures and lighting chosen with our designer, before anything is ordered.
Pre-construction
Permits, approvals, ordering and a firm schedule, all settled before the first wall comes down.
Construction
A dedicated project manager, protected floors and a clean, orderly site at the end of every day.
Walkthrough
A final review together, every punch-list item closed, and a home that's ready to live in.

Questions
Garage questions
Do I need a permit to build a garage?
Yes. Garages need a building permit and must meet setback and accessory-structure rules. Several small cities and HOAs in our area also review plans. We handle all of it.
Can I convert my garage into a bedroom or family room?
Usually. Conversions need building, electrical and mechanical permits, insulation, heating and cooling, and egress for a bedroom. In some HOAs, like Lake Forest, you must keep a minimum number of garage spaces, so a conversion may pair with a new garage.
Can I build an apartment over a garage?
In many Louisville Metro single-family zones, accessory dwelling units are now allowed with administrative review. Small cities with their own zoning have their own rules. We'll check your address.
Can a new garage match my brick house?
Yes. We source brick and match rooflines, trim and windows so the garage looks original.
Should I plan for an EV charger?
Yes. Even if you don't own an electric vehicle yet, adding capacity and a circuit during construction costs far less than retrofitting.
How much does a garage cost?
It depends on size, foundation, finishes, and whether there's living space above. See our cost guide.
