Custom Spaces Designed for the Way You Live
Thoughtfully designed ADUs, garages, guest houses, workshops, and outbuildings that add useful space while complementing your home and property.
The best detached buildings begin with more than a floor plan. The size of your property, intended use of the space, access, utilities, privacy, storage needs, and relationship to your existing home all play a role in creating a building that works well for years to come.
At English Home Improvements, we take a design-build approach to custom detached structures throughout Gallatin and Middle Tennessee. Whether you are planning a simple detached garage, a fully finished accessory dwelling unit, a garage apartment, guest house, workshop, horse barn, or multi-purpose outbuilding, we can help coordinate the many elements involved in bringing the project together.
From foundations and structural construction to roofing, siding, windows, doors, electrical, plumbing, insulation, interior finishes, cabinetry, and outdoor spaces, our team can manage the project as one coordinated build. Exterior materials and architectural details can also be selected to complement your existing home and help the new structure feel like it has always belonged on the property.
ADU Zoning, Permits & Property Requirements
A successful ADU or detached building project starts with understanding what can be built on your property.
Accessory dwelling units, garage apartments, guest houses, detached garages, and other outbuildings may be subject to local zoning and building requirements. What is permitted can vary depending on the property’s location, zoning classification, lot size, existing structures, and the type and intended use of the new building.
Before construction begins, important factors may need to be evaluated, including property setbacks, building size and height, lot coverage, access, parking, utility connections, easements, drainage, and septic or sewer capacity. Projects that include finished living space may also have additional requirements for electrical, plumbing, heating and cooling, insulation, emergency egress, and other life-safety provisions.
At English Home Improvements, we understand that these considerations are an important part of planning a successful project. As a licensed Residential and Commercial General Contractor, we can help homeowners navigate the construction process and coordinate the different components involved in taking a project from concept through completion.
Because requirements can differ between Gallatin, Sumner County, surrounding Middle Tennessee communities, and individual properties, each project should be evaluated based on the regulations and conditions that apply to that specific location.

Benefits of an ADU, Garage Apartment or Custom Outbuilding
More Usable Space
Gain valuable square footage without changing the footprint of your primary home. A detached structure can provide living, working, recreational, or storage space while keeping those activities separate from the main house.
Flexible Living Options
Create comfortable, private accommodations for family, guests, adult children, or aging parents. ADUs and garage apartments can incorporate bedrooms, bathrooms, kitchens, living areas, and independent entrances when appropriate for the project.
Dedicated Work & Hobby Space
Create a home office, studio, workshop, hobby room, or specialized workspace without sacrificing valuable rooms inside your home.
Vehicle & Equipment Storage
Protect vehicles, recreational equipment, tools, lawn equipment, and other belongings with garage and storage space designed around what you actually need to store.
Long-Term Flexibility
Your needs may change over time. Thoughtful planning can create spaces capable of adapting as your family, work, hobbies, or storage requirements evolve.
Designed to Complement Your Property
Rooflines, siding, stone, windows, doors, porches, and other architectural details can be coordinated with your existing home so the new structure feels like a natural part of the property.
A well-planned detached building can solve today’s space needs while giving your property greater flexibility for the future.
Frequently Asked Questions About ADU Building in Gallatin, Middle Tennessee and Western Kentucky
What is an accessory dwelling unit (ADU)?
An accessory dwelling unit, commonly called an ADU, is a secondary living space located on the same property as a primary residence. An ADU may be a detached structure, part of a garage, or living space above a garage. Depending on local requirements and the project design, it can include a kitchen, bathroom, bedroom, living area, and private entrance.
Can you build a detached garage with an apartment above it?
Yes. English Home Improvements can design and build detached garages with finished second-story living space. Garage apartments can be planned with bedrooms, bathrooms, kitchens, living areas, offices, storage, and private entrances based on your needs and applicable local building requirements.
Can an ADU include a full kitchen and bathroom?
Yes, when permitted for the property and project. A custom ADU can be designed with a full kitchen, bathroom, bedroom, living area, laundry space, and other features that create a comfortable, independent living environment. Local zoning, utilities, septic or sewer capacity, and permitting requirements may affect what can be built.
Do you build detached garages without living space?
Absolutely. We build custom detached garages for vehicle storage, equipment, recreational vehicles, workshops, hobbies, and general storage. Garages can be designed with one or multiple bays and customized with storage areas, electrical service, lighting, windows, exterior doors, and other features.
Can you match a new garage or ADU to my existing home?
Yes. Rooflines, roofing materials, siding, stone or masonry, trim, windows, doors, colors, porches, and other architectural details can be selected to complement your existing home. Our goal is to create a new structure that works well on your property and feels like a natural part of it.
Can you build a home office, studio, or workshop instead of an ADU?
Yes. Not every detached building needs to be a residence. English Home Improvements can build custom home offices, studios, workshops, hobby spaces, garage and workshop combinations, and other multi-purpose buildings designed around how you intend to use the space.
Do ADUs and garage apartments require permits?
Most ADUs, garage apartments, detached garages, and substantial outbuildings require some level of permitting. Requirements can vary by city, county, zoning classification, property, and intended use. Setbacks, building size and height, utilities, parking, easements, septic or sewer capacity, and other property conditions may also affect the project.
How much does it cost to build an ADU or garage apartment?
The cost varies considerably depending on the size and design of the building, site conditions, foundation, utility connections, number of garage bays, interior layout, kitchens and bathrooms, exterior materials, and level of finish. English Home Improvements provides free estimates so we can evaluate your project and discuss the features you would like to include.
How long does it take to build an ADU or detached garage?
Construction timelines vary based on the size and complexity of the project, site preparation, permitting, utility work, weather, material availability, and interior finishes. A simple detached garage will generally involve fewer construction phases than a fully finished ADU or garage apartment. We can provide a more realistic project timeline once the scope and property requirements are understood.
